1,3-丙二醇(1,3-PD)主要应用于油墨、涂料、化妆品、制药、防冻剂等行业,它最重要的用途是作为聚酯、聚醚和聚亚氨酯的单体[1]。由它合成的聚酯,如聚对苯二甲酸丙二醇酯(PTT),有独特的性质和优异的性能,而且可以使聚酯塑料具有易于自然循环的可生物降解特性[2]。目前,1,3-丙二醇的生产主要是以石油裂解的乙烯和丙烯为原料,在高温和重金属催化剂的作用下化学合成的。这
1,3-Propanediol (1,3-PD) is mainly used in the printing ink, paint, cosmetics, pharmaceuticals, antifreeze and other industries, its most important use is as a polyester, polyether and polyurethane monomer [1 ]. Polyesters such as polytrimethylene terephthalate (PTT), which are synthesized from it, have unique properties and excellent properties, and allow polyester plastics to have biodegradable properties that are easy to circulate naturally [2]. At present, the production of 1,3-propanediol is mainly based on petroleum cracking ethylene and propylene as raw materials, chemical synthesis under the action of high temperature and heavy metal catalysts.
