Abstract

See full text

A plasticizer and a method for producing the same are provided. The method for producing the plasticizer includes: reacting a reaction mixture at each of a plurality of temperature holding stages in a heating process to form a semi-finished product; and purifying the semi-finished product at each of a plurality of low pressure stages of a decompression process to obtain a plasticizer. A temperature range of the heating process is from 140° C. to 220° C., a pressure range of the decompression process is from 750 Torr to 20 Torr, and the reaction mixture contains dibasic acid (e.g., adipic acid), diol (e.g. 1,4-butanediol), monohydric alcohol (e.g., 2-ethylhexanol), and catalyst (e.g., titanium catalyst).
