摘要
简述了聚对苯二甲酸丙二酯 ( PTT)的特性、我国 PTT的发展状况 ,阐述了纤维级 1,3-丙二醇的研制、开发与生产对 PTT发展的重要性。着重介绍丙烯醛水合加氢法生产 1,3-丙二醇的工艺 ,并对丙烯醛水合反应、3-羟基丙醛加氢反应、4-氧代 -1,7-庚二醇水解反应、1。
The properties, application and development situation of polytrimethylene terephthalate(PTT) were introduced. The importance of research, development and production of fiber-grade 1,3-propanediol to the development of PTT was stated. The hydration of acrolein, hydrogenation of 3-hydroxypropanal, hydrolysis of 4-oxo-1,7-heptanediol, purification of 1,3-propanediol, reaction conditions and catalysts were emphasized for the production process of 1,3-PDO from acrolein by hydration and hydrogenation.
