METHOD FOR PRODUCING MONOCARBOXYLIC ACID TERTIARY-ALKYL ESTER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a monocarboxylic acid tertiary- alkyl ester with a high purity and in high yield. SOLUTION: Monocarboxylic acid tertiary alkyl ester expressed by formula (1) (R1 represents a hydrocarbon group; and R2 represents a tertiary saturated hydrocarbon group) is obtained by sequentially adding an esterifying agent having a monovalent acid group to a mixed solution comprising a monocaboxylic acid and a tertiary alcohol. A halogenated aromatic sulfonyl is used for the esterifying agent and an amide is used for catalyst. The concrete example of formula 1 is a compound expressed by formula (4).
