PRODUCTION OF ESTER MIXTURE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an ester mixture used as a plasticizer for a plastic product at a low cost while controlling a composition.SOLUTION: There can be produced an ester mixture by a method of reacting an acid A (COOH)or a derivative thereof and an alcohol ROH having a lower boiling point in an amount of (m+s) and an alcohol ROH having a higher boiling point in an amount of mwith ROH. A represents an alkylene and a phenylene. mand mcorrespond to a molar equivalent of alcohol groups OR1 and OR2 introduced into A (COOH)or a derivative thereof and sis larger than 0 and in the range from 0.05 to 0.60 times (m+m).SELECTED DRAWING: Figure 1
