Kinetics of Alkaline Hydrolysis of Esters. II. Unsaturated Esters and Oxalic Esters [PDF]
Bulletin of the Chemical Society of Japan, 1970 Abstract The kinetics of alkaline hydrolysis of some typical esters, with unsaturation in the alkyl and the acyl portions, was studied. It was found that, in general, unsaturation results in enhancing the rate as compared to that of the corresponding saturated esters, provided that there is no conjugation between the double bond and the ...

Production of polyvinyl esters by ester interchange [PDF]
Journal of the American Oil Chemists' Society, 1955 SummaryMixed polyvinyl esters of acetic acid and higher fatty acids can be made by ester interchange between polyvinyl acetate and fatty esters. Their properties indicate that some of these products merit attention as materials for use in the drying oil industries.
