Abstract
A diisononyl terephthalate (DINT) plasticizer is synthesized by esterifying an isononanol mixture composed of multiple alcohols with pure terephthalic acid in the presence of an esterification catalyst, and the DINT plasticizer due to featuring a low plasticizer migration below 1.4% and a low glass transition temperature below −75° C. is so suitable for making those soft plastic products, such as hoses, wires, cables, exercise mats, table mats, playing balls or disposable gloves, required for having a high content of plasticizers more than 70 PHR.
