Abstract

Abstract: Plasticizer diisooctyle terephthalate(DOTP)were synthesized from industrial waste phthalic anhydride which rich in pure terephalic acid(PTA) and iso-octanol. The effects of different conditions were studied. The results showed that the optimum conditions were as follows: tetrabutyl titanate has good catalytic effect, the amount of catalyst 0.2%, reaction temperature 240℃ and reaction time 4h. Under these conditions the conversion rate was >99% and purity was 94%. Compare to the current process(reaction after pretreatment), it will be decrease of many steps,such as alkalization, purification and evaporation etc. Impurities can be removed in the product purification and the product has good quality.

Key words: plasticizers, esterification, diisooctyle terephthalate (DOTP)
