The effect of diglyme on the kinetics of chromium(III) ethanoate-catalyzed reactions of carboxylic acids with epichlorohydrin
The kinetics of reaction between acetic, acrylic, or methacrylic acid and epichlorohydrin in diglyme solution are studied with chromium(III) ethanoate as catalyst. The reaction has been found to be of first-order with respect to both epichlorohydrin and catalyst and zeroth order with respect to acid. Relative reactivities of the acids in reaction with epichlorohydrin and regioselectivity of the addition in diglyme are compared with those for the systems without solvent.
Reactivity of some carboxylic acids in reactions with some epoxides in the presence chromium (III) ethanoate
Reactivities have been compared of acetic, acrylic, and methacrylic acid in reactions with epichlorohydrin, phenylglycidyl ether, glycidyl acetate, and glycidyl methacrylate carried in the presence of chromium (III) ethanoate. The acid reactivities changed differently with respect to the oxirane series. The effect of solvents on the reactions of acids with epichlorohydrin has also been observed.

A Convenient Synthesis of Glycidyl Esters (2,3-Epoxypropyl Alkanoates)
A novel method for synthesizing glycidyl esters (2,3-epoxypropyl alkanoates) 1 has been achieved by the sequence of the organotin phosphate catalyzed reaction of epichlorohydrin 2 with carboxylic acids and dehydrochlorination of the resulting mixture of ester chlorohydrins 3 + 4 followed by separation.
