Document Type and Number:

WIPO Patent Application WO/2022/065853

Kind Code:

A1

Abstract:

The present invention relates to a method for producing an ester-based composition, characterized in that a plurality of batch reactors are operated sequentially, and the pressure inside each reactor is controlled, wherein the ester-based composition is semi-continuously produced, and thus productivity is high, and the batch reactors are stable.
