Title:
PRODUCTION OF ESTER
Document Type and Number:
Japanese Patent JP3273498
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a production process for ester with reduced content of aliphatic alcohol or alkyl-substituted phenol without adverse effect on its heat resistance and other physical properties.
SOLUTION: (A) An aliphatic or aromatic mono-, di- or tricarboxylic acid or an inorganic acid or their halides and (B) an aliphatic alcohol or an alkyl- substituted phenol are allowed to react with each other, in a chemically equivalent or less amount of (B) to (A). Then, the reaction mixture is allowed to react with (C) an excessive amount of an aliphatic alcohol, phenol or an alkyl- substituted phenol boiling at a lower temperature than the boiling point of (B) to prepare mixed esters. According to this process, the post-treatment process as purification process can be simplified and the shortened production time and the cost saving can be attained.
