A method for evaluating repellents by using rabbits is described. The repellent effect of 279 compounds was tested against Culex pipiens molestus. Eighty-seven of these compounds were also tested against Aedes aegypti. The most effective compound against both species was 2-ethoxy-N,N-diethylbenzamide (I). Two compounds, 1,1-dimethylpropyl m-chlorocarbanilate and l-ethylpropyl m-chlorocarbanilate, were highly effective against C. pipiens molestus but not A. aegypti; an addnl. 6 compounds were particularly effective against C. pipiens molestus: sec-Bu N,N-diisopropylsuccinamate, N-n-amyl-3,6-endo-methylene-4-cyclohexene-1,2-dicarboximide, Et β-benzoylacrylate, 2-(dicyclohexylamino)ethanol, N-hexyl-butyramide, and I. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Recommanded Product: 115-84-4).

2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) 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. 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.Recommanded Product: 115-84-4

New polyester intermediates for powder coatings was written by Johnson, Larry K.;Sade, William T.. And the article was included in Proceedings of the Waterborne, High-Solids, and Powder Coatings Symposium in 1991.Quality Control of 2-Butyl-2-ethylpropane-1,3-diol The following contents are mentioned in the article:

All-aliphatic powder coatings for improved UV resistance could be prepared using 1,4-cyclohexanedicarboxylic acid as the sole diacid component if the formulation contained a glass temperature (T_g)-enhancing glycol such as hydrogenated bisphenol A. The melt viscosities of polyesters for powder coatings could be reduced by the incorporation of 1,3-cyclohexanedicarboxylic acid. Hydroxypivalyl hydroxypivalate reduced both the T_g and melt viscosity of resins into which it was incorporated as a partial replacement for neopentyl glycol. The use of 2-butyl-2-ethyl-1,3-propanediol had an effect on the T_g that was less than predicted based on its structure. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Quality Control of 2-Butyl-2-ethylpropane-1,3-diol).

Test for the comparison of glass-resin adhesion in laminates, application to glass-polyene ester laminates was written by Zalmanski, Alain. And the article was included in Bulletin de la Societe Chimique de France in 1970.Formula: C9H20O2 The following contents are mentioned in the article:

The adhesion of glass fibers to the polyester matrix in the reinforced laminates was determined by measuring the difference between the bending resistance of the reinforced laminate and the pure resin. The glass fiber content, type of the resin, the modifying diacid, the unsaturation mode of the polyester, and the type of the glycols and monomers used were the main parameters affecting adhesion. An improvement in adhesion was observed when using a polyester containing ∼25% maleic anhydride; modifying with tetrahydro- or hexahydrophthalic anhydride; using neopentyl glycol or 1,3-butylene glycol; and the partial replacing of styrene with Me methacrylate, ethylene glycol dimethacrylate, or chlorostyrene. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Formula: C9H20O2).

Metal-free alcohol-directed regioselective heteroarylation of remote unactivated C(sp³)-H bonds was written by Wu, Xinxin;Zhang, Hong;Tang, Nana;Wu, Zhen;Wang, Dongping;Ji, Meishan;Xu, Yan;Wang, Min;Zhu, Chen. And the article was included in Nature Communications in 2018.Application In Synthesis of 3,7-Dimethyloctan-1-ol The following contents are mentioned in the article:

A practical and elusive metal-free alc.-directed heteroarylation of remote unactivated C(sp³)-H bonds was disclosed. Phenyliodine bis(trifluoroacetate) (PIFA) was used as the only reagent to enable the coupling of alcs. and heteroaryls. Alkoxy radicals were readily generated from free alcs. under the irradiation of visible light, which trigged the regioselective hydrogen-atom transfer (HAT). A wide range of functional groups were compatible with the mild reaction conditions. Two unactivated C-H bonds were cleaved and one new C-C bond was constructed during the reaction. This protocol provides an efficient strategy for the late-stage functionalization of alcs. and heteroaryls. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Application In Synthesis of 3,7-Dimethyloctan-1-ol).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) 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. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Application In Synthesis of 3,7-Dimethyloctan-1-ol

Herein, sulfamides served as amine surrogates to guide intermol. chlorine-transfer at γ-C(sp³) centers. This unusual position-selectivity arised because accessed sulfamidyl radical intermediates engaged preferentially in otherwise rare 1,6-hydrogen-atom transfer (HAT) processed through seven-membered transition states. The site-selectivity of C-H abstraction could be modulated by adjusting steric and electronic properties of sulfamide nitrogen substituents, an ability that had not been demonstrated with other substrate classes.
