Abstract

1,155,543. Glycidyl ethers and esters. DOW CHEMICAL CO. 29 March, 1967, No. 14281/67. Heading C2C. Glycidyl ethers and esters are obtained in a two stage process comprising mixing an organic hydroxy compound or a carboxylic acid in the presence of a basic catalyst with sufficient epichlorohydrin to dissolve the intermediate chloro ether or ester and contacting the resultant solution at 0-100‹ C. with an aqueous solution of an alkali metal carbonate containing an alkali metal hydroxide in an amount ranging from a slight excess of the stoichiometric quantity required to twice the stoichiometric quantity required for dehydrohalogenation and recovering the ester or ether by distillation. An anion exchange resin or a quaternary ammonium compound may be used as the basic catalyst in the first stage. Dehydrohalogenation is preferably effected at 20-75‹ C. using a NaOH/ Na 2 CO 3 solution saturated in respect of carbonate. Examples relate to the preparation of the diglycidyl ether of bisphenol A, phenyl glycidyl ether and glycidyl acrylate.
