杂多酸HPW_(12)催化合成柠檬酸三正丁酯的研究

Study on synthesis of tri-n-butyl citrate by using heteropoly acid HPW 12 as the catalyst

柠檬酸三正丁酯简称TBC ,分子式为C1 8H3 2 O7,该产品是一种良好的无毒增塑剂 ,广泛用于聚乙烯、聚氯乙烯、聚丙烯和多种纤维素树脂的增塑 ,以及食品包装材料和医疗用具的增塑剂。采用HPW1 2 杂多酸为催化剂合成TBC 。

TBC is the abbrevication of Tr-n-butyuitrat.Its molecular formula is C 18 H 32 O 7.It is a fine and nopoisonous plasticiser. It is applied exiensively to plastieizer of polypropylene and variety of cellulose resin as well as that of packing materecl for food and medicial apparatus.We have made great achievement in synthesis of TBC by means of heteropoly acid as a catalyst.
