分子筛催化合成柠檬酸酯类增塑剂的研究进展

The Research Progress of Citrate Esters Plasticizers Catalyzed by Zeolite

因具有相容性好、增塑性能强、毒性小、挥发性低、耐候性强等优点,柠檬酸酯类增塑剂目前已然成为首选替代DOP等传统增塑剂的绿色环保产品;目前应用于工业生产柠檬酸酯类增塑剂的催化剂种类繁多,分子筛作为一种具有特定均一有序空间结构的新型催化剂,具有催化活性高、稳定性好和抗毒能力强、易回收循环利用等优点,可满足不同的增塑剂合成的要求,符合绿色环保的要求。对分子筛在增塑剂柠檬酸酯合成反应中的重要作用及进展进行了综述,并探讨了其未来的发展趋势。

With good peculiarity of compatibility,plasticizing efficiency,non-toxic,nonvolatile,strong weatherability,etc,the citrate esters plasticizers,a green environmental protection product,now has attracted widely attention and become the first choice to replace phthalic acid esters. As one kind of catalysts used in citrate esters plasticizers synthesis reaction,Zeolite with specific spatial structure have advantages of high activity,stability,anti-poison ability,and recyclable recycling,which meet the different requirements of the citrate esters plasticizers synthesis reaction and environmental protection. In this paper,the important role and mechanism of molecular sieves in the preparation of citrate esters are reviewed,and the future trend of molecular sieve is also discussed.
