Manufacturing method of bis(2-ethylhexyl) terephthalate

The invention relates to a manufacturing method of bis(2-ethylhexyl) terephthalate, which comprises: performing an esterification reaction of terephthalic acid and 2-ethyl hexanol in the presence of a chelating catalyst. The method of the invention can increase the reaction speed, improve the filtering efficiency of the esterified product, and prepare bis(2-ethylhexyl) terephthalate with low hue (APHA).
