The ice-forming activity was studied of 2,4-dioxybenzoic acid (I) [89-86-1], the mol. of which crystallizes with 3 H₂O mols. The specific yield of ice crystals ranges (1.7-8.8) × 10⁹/1 g, in relation to the amount of I added (0.45-1.25 mL) to the solution The anhydrous form of I has a better ice-forming activity than the crystal-hydrates. Comparative data are also obtained for cis-terpin and its crystal hydrate. In the experiment, the researchers used many compounds, for example, rel-(1s,4s)-4-(2-Hydroxypropan-2-yl)-1-methylcyclohexanol hydrate (cas: 2451-01-6Name: rel-(1s,4s)-4-(2-Hydroxypropan-2-yl)-1-methylcyclohexanol hydrate).

rel-(1s,4s)-4-(2-Hydroxypropan-2-yl)-1-methylcyclohexanol hydrate (cas: 2451-01-6) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Name: rel-(1s,4s)-4-(2-Hydroxypropan-2-yl)-1-methylcyclohexanol hydrate

Efficient Aluminum Catalysts for the Chemical Conversion of CO₂ into Cyclic Carbonates at Room Temperature and Atmospheric CO₂ Pressure was written by Kim, Yoseph;Hyun, Kyunglim;Ahn, Duseong;Kim, Ran;Park, Myung Hwan;Kim, Youngjo. And the article was included in ChemSusChem in 2019.Safety of 1-(Dimethylamino)-2-methylpropan-2-ol This article mentions the following:

A series of dimeric aluminum compounds [Al(OCMe₂CH₂N(R)CH₂X)]₂ [X = pyridin-2-yl, R = H (Pyr^H); X = pyridin-2-yl, R = Me (Pyr^Me); X = furan-2-yl, R = H (Fur^H); X = furan-2-yl, R = Me (Fur^Me); X = thiophen-2-yl, R = H (Thio^H); X = thiophen-2-yl, R = Me (Thio^Me)] containing heterocyclic pendant group attached to the nitrogen catalyze the coupling of CO₂ with epoxides under ambient conditions. In a comparison of their catalytic activities with those of aluminum complexes without pendant groups at N [X = H, R = H (H^H); X = H, R = Me (H^Me)] or with non-heterocyclic pendant groups [X = CH₂CH₂OMe, R = H(OMe^H); X = CH₂CH₂NMe₂, R =H(NMe₂^H); X = CH₂CH₂NMe₂, R = Me (NMe₂^Me)], complexes containing heterocycles, in conjunction with (nBu)₄NBr as a cocatalyst, showed higher catalytic activities for the synthesis of cyclic carbonates under the same ambient conditions. The best catalyst system for this reaction is Pyr^H/(nBu)₄NBr system, which gives a turnover number of 99 and a turnover frequency of 4.1 h^-1, making it 14- and 20-times more effective than H^H/(nBu)₄NBr and HMe/(nBu)₄NBr, resp. Although there were no direct interactions between the aluminum and the heteroatoms in the heterocyclic pendants, electronic effects combined with the increased local concentration of CO₂ around the active centers influences the catalytic activity in the coupling of CO₂ with epoxides. In addition, Pyr^H/(nBu)₄NBr showed broad epoxide substrate scope and seven terminal epoxides and two internal epoxides undergo the designed reaction. In the experiment, the researchers used many compounds, for example, 1-(Dimethylamino)-2-methylpropan-2-ol (cas: 14123-48-9Safety of 1-(Dimethylamino)-2-methylpropan-2-ol).

1-(Dimethylamino)-2-methylpropan-2-ol (cas: 14123-48-9) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Safety of 1-(Dimethylamino)-2-methylpropan-2-ol

And the article was included in Organic Letters in 2015.Name: (R)-1-(3-Chlorophenyl)ethanol This article mentions the following:

A facile development of chiral alkenylboranes (e.g., I) by the hydroboration of chiral diynes with Piers’ borane was successfully achieved for the first time. With the combination of the in situ generated chiral alkenylboranes and tri-tert-butylphosphine as frustrated Lewis pair catalysts, the metal-free asym. hydrogenation of silyl enol ethers was realized to furnish a wide range of optically active secondary alcs. in high yields and up to 99% ee. In the experiment, the researchers used many compounds, for example, (R)-1-(3-Chlorophenyl)ethanol (cas: 120121-01-9Name: (R)-1-(3-Chlorophenyl)ethanol).

(R)-1-(3-Chlorophenyl)ethanol (cas: 120121-01-9) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Name: (R)-1-(3-Chlorophenyl)ethanol

And the article was included in New Biotechnology in 2014.HPLC of Formula: 5743-47-5 This article mentions the following:

Extreme halophilic Archaea are extremophile species which can thrive in hypersaline environments of up to 3-5 M sodium chloride concentration Although their ecol. and physiol. are widely identified on the microbiol. level, little emphasis has been laid on quant. bioprocess development with extreme halophiles.The goal of this study was to establish, on the one hand, a methodol. basis for quant. bioprocess anal. of extreme halophilic Archaea with an extreme halophilic strain as an example. Firstly, as a novel usage, a corrosion resistant bioreactor setup for extreme halophiles has been implemented. Then, paying special attention to total bioprocess quantification approaches, an indirect method for biomass quantification using online process signals was introduced. Subsequently, robust quant. data evaluation methods for halophiles could be developed, providing defined and controlled cultivation conditions in the bioreactor and therefore obtaining suitable quality of online as well as off-line datasets.On the other hand, new physiol. results of extreme halophiles in bioreactor have also been obtained based on the quant. methodol. tools. For the first time, quant. data on stoichiometry and kinetics were collected and evaluated on different carbon sources. The results on various substrates were interpreted, with proposed metabolic mechanisms, by linking to the reported primary carbon metabolism of extreme halophilic Archaea. Moreover, results of chemostat cultures demonstrated that extreme halophilic organisms show Monod-kinetics on different sole carbon sources. A diauxic growth pattern was described on a mixture of substrates in batch cultivations.In addition, the methodologies presented here enable one to characterize the utilized strain Haloferax mediterranei (HFX) as a potential new host organism. Thus, this study offers a strong methodol. basis as well as a fundamental physiol. assessment for bioreactor quantification of extreme halophiles that can serve as primary knowledge for applications of extreme halophiles in biotechnol. In the experiment, the researchers used many compounds, for example, Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5HPLC of Formula: 5743-47-5).

Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.HPLC of Formula: 5743-47-5

And the article was included in Chemical Papers in 2022.COA of Formula: C7H7ClO This article mentions the following:

A facile and efficient oxidation of alc. by Fe²⁺ activating persulfate was performed and a homogeneous/biphasic reaction switch strategy was proposed to regulate the oxidation process. Na₂S₂O₈ and FeSO₄ were employed as the oxidant and the source of activator Fe(II), resp. Fe²⁺ efficiently excited persulfate, endowing persulfate with powerful oxidation activity. Benefited from this, the oxidation of benzylic primary alcs. and cyclic secondary alcs. could proceed to give the corresponding aldehydes or ketones with good yields (85.2-98.5%) under the optimal conditions of 60°C, 1.5 mol equivalent Na₂S₂O₈ and 0.3 mol equivalent Fe²⁺ to substrate in a water/dichloroethane biphase system. Moreover, the primary alcs. were one-step oxidized into carboxylic acids with high selectivity by raising reaction temperature, increasing the amount of oxidant and switching from biphasic reaction to the water/MeCN homogeneous phase. In the experiment, the researchers used many compounds, for example, (4-Chlorophenyl)methanol (cas: 873-76-7COA of Formula: C7H7ClO).

And the article was included in Nanomaterials in 2020.Quality Control of ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) This article mentions the following:

Fabrication of low-cost, durable and efficient metal oxide nanocomposites were successfully synthesized and reinforced with photo-resin via 3-dimensional printing. Here, we put forward a novel approach to enhance the mech. and thermal behaviors of stereolithog. (SLA) 3D printed architecture by adding TiO₂ nanoparticles (TNPs) in different crystalline phases (anatase and rutile), which were obtained at different annealing temperatures from 400°C to 1000°C. The heat-treated anatase TNPs were scrutinized by X-ray diffraction, XPS, Raman spectroscopy, diffusive reflectance spectroscopy, and transmission electron microscopy anal. Among all the samples, at 800°C, annealed anatase TNPs exposed a highly crystalline anatase phase, having a low energy band gap and a comparably high tensile strength (47.43 MPa) and high elastic modulus (2.261 GPa) for the 3D printed samples, showing improvement by 103% and 32%, resp., compared with the printed pristine stereolithog. resin (SLR) sample. Moreover, enhanced storage modulus and tan δ values were achieved via the better interfacial interactions between the incorporated nanofillers and the SLR matrix. In addition to this, enhanced thermal conductivity and thermal stability of the SLR matrix were also noted. The low energy bandgap and nanoscale size of the fillers helped to achieve good dispersion and allowed the UV light to penetrate at a maximum depth through the photo resin.

The preparation of buttermilk fortified with Ca and Mg salts and whey protein concentrate (WPC-68) was studied. Different amounts of Ca lactate or citrate, Mg gluconate or hydroaspartate, and WPC or their mixtures were added to milk samples. The impact on milk thermal stability during 15-s re-pasteurization at 74°C and resulting pH was determined Protein clots were formed after the milk thermal processing. When a mixture of Ca citrate, Mg hydroaspartate, and Mg gluconate was used, it was possible to fortify the milk at least to 72 mg% Ca and ∼30 mg% Mg. The addition of the 2 Mg salts did not coagulate the milk proteins during re-pasteurization and the active acidity was pH >6.52.
