“…13,14 It shows excellent catalytic performance and catalytic activity in catalytic esterification and transesterification. 15,16 The alcoholysis of PET is a kind of transesterification reaction in principle, so this paper explores the application of TiO(acac) 2 in the catalytic alcoholysis of PET. 17,18 The work of this paper is as follows: firstly, titanium diisopropoxide bis(acetylacetonate) was synthesized by a one-pot method using acetylacetone and isopropyl titanate as raw materials; here, our synthesis method is different from the past and has been improved.…”
