Changes of volatile compounds in polyethylene terephthalate bottles during storage was written by Ikegami, Tohru;Nagashima, Kazufumi;Shimoda, Mitsuya;Osajima, Yutaka. And the article was included in Nippon Shokuhin Kogyo Gakkaishi in 1990.HPLC of Formula: 2451-01-6 This article mentions the following:
Hydrocarbons, esters, aldehydes, and alcs. were dissolved in citric acid solution (pH 2.7) containing gum arabic and aseptically filled into polyethylene terephthalate (PET) bottles. Sorption of volatile compounds on PET bottle was slight. Aliphatic aldehydes were oxidized by dissolved O, forming the corresponding carboxylic acids, but cyclic aldehydes were stable in PET bottles. The Et alkanoates were hydrolyzed to carboxylic acids in PET or glass bottles; however, in a pouch lined with middle-d. polyethylene film, since the Et alkanoates sorbed into the liner predominantly, the extent of hydrolysis was much smaller. The interconversions of terpene alcs. led to formation of 2,6,6-trimethyl-2-vinyltetrahydropyran, terpin hydrate, and α-terpineol in any type of container. Food flavor deterioration in PET bottles during storage was not due to sorption but to chem. changes of volatile compounds In the experiment, the researchers used many compounds, for example, rel-(1s,4s)-4-(2-Hydroxypropan-2-yl)-1-methylcyclohexanol hydrate (cas: 2451-01-6HPLC of Formula: 2451-01-6).
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. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.HPLC of Formula: 2451-01-6
