Process for preparing alkyl 4,4'-(ethylenedioxy)bis-benzoates

Alkyl 4,4'-(ethylenedioxy)bis-benzoates having improved properties such as anti-oxidation and anti-coloration are prepared in high yield and selectivity by, at the first step, reacting an excess alkyl p-hydroxybenzoate with a recycling alkyl p-(2-chloro-ethoxy)benzoate with heating in the presence of an alkali carbonate and an inert organic solvent until almost said alkyl p-(2-chloroethoxy)benzoate is consumed to produce an alkyl 4,4'-(ethylenedioxy)bis-benzoate and at the second step adding ethylene dichloride to the reaction system and continuing the heating to produce an alkyl p-(2-chloroethoxy)benzoate which is recycled, and separating the alkyl 4,4'-(ethylenedioxy)bis-benzoate produced.
