Kinetics of alcoholysis of poly(ethylene terephthalate) in sub- and super-critical isooctyl alcohol to produce dioctyl terephthalate

Dioctyl terephthalate (DOTP) obtained from waste PET is an oily substance and is compatible with concrete raw materials, which can make it an attractive material to be used as building materials. For this reason, the performance of DOTP-reinforced concrete is important for determining the direction of waste PET disposal.

Bis(2-ethylhexyl) terephthalate

Bis(2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. It is a non- phthalate plasticizer , being the diester of terephthalic acid and the branched-chain 2-ethylhexanol , which is often generically referred to as octyl.

The reaction process of direct esterification is shown in Fig. 1. It is a two-step consecutive reaction. First, mono-2-ethylhexyl terephthalate (MEHTP) is obtained by esterification of PTA and 2-EH in the presence of catalyst. Then, the MEHTP further reacts with 2-EH to produce DOTP. Note that PTA is almost insoluble in liquid-phase system at
