Ethylhexyl terephthalate （DOTP） is anenvironmentallyfriendly poly（vinyl chloride）-type plasticizer which is recently developed. The esterification reaction is one of the most comonly used methods. This paper mainly introduced several catalysts which are commonly used in the esterification synthesis of DOTP starting from terephthalic acid, and their advantages and disadvantageswere compared. Recent study progress of the esterification synthesis of DOTP was maily revieved, heterogeneous reaction has a direct inhibition to the reactionrate and the ionic liquids has a positive action on the homogeneous reaction which may result in the reduction of the reaction time were pionted out.
