発明の名称 (英語) Method for producing ester condensed product
発明の概要(英語) A method for producing an ester condensed product, wherein an esterification reaction is effected by using a catalyst comprising a zirconium (IV) compound and/or a hafnium (IV) compound and an iron compound and/or a gallium compound; and a catalyst for use in the method.
It is preferred that the zirconium (IV) compound is a compound represented by Zr(OH)a(OR1)b[wherein R 1 represents an acyl group or alkyl group, and each of a and b is 0 or an integer of 1 to 4 and the relationship of a + b = 4 is satisfied] or a zirconium (IV) halide.
The method allows the production of an ester condensed product having a specific structure by the reaction of equimolar amounts of a carboxylic acid and an alcohol, with the inhibition of the formation of by-products, in good yield, on a large scale, and the catalyst exhibits good catalytic efficiency and is used in a small amount, is reusable and can be repeatedly used.
The method can thus provide an industrial process which is desirable from the view point of green chemistry.
