alternative route is developed to prepare PCTA monomer with plant-based acrylate and acetaldehyde as the feedstocks. The features include catalytic MBH reaction, one-step dehydration/Diels–Alder reaction over H2SO4/SiO2 catalyst, and Pd/C-catalyzed dehydrogenation. In addition, commonly used plasticizer di(2-ethylhexyl) benzenedicarboxylate and monomer UNOXOL™ diol can also be manufactured.
开发了一种替代路线,以植物基丙烯酸酯和乙醛为原料制备 PCTA 单体。其特征包括催化MBH反应、H 2 SO 4 /SiO 2催化剂上的一步脱水/Diels-Alder反应和Pd/C催化脱氢。此外,还可生产常用的增塑剂二(2-乙基己基)苯二甲酸酯和单体UNOXOL™二醇。
