用途本品为无毒增塑剂,可用于无毒PVC造粒,制作食品包装材料,儿童软质玩具,医用制品,聚氯乙烯、氯乙烯共聚物、纤维素树脂的增塑剂。

用途主要用作乙烯基树脂和纤维素树脂的增塑剂

制备方法 · 1 条

生产方法1.柠檬酸和正丁醇(投料比1∶1)在硫酸(投料量为柠檬酸和正丁醇总质量的0.3%)的作用下,于150℃回流4~5h,当反应物的酸值降至1mgKOH/g以下时,即为酯化终点。产物经活性炭脱色、过滤、中和、水洗、减压蒸馏,釜液即为成品。 精制方法:含有游离的酸和醇等杂质。精制时用无水碳酸钾或硫酸钠干燥后减压精馏。 2.制法: 于1L圆底烧瓶中加入柠檬酸(2)315g(1.0mol),正丁醇500g(6.7mol),1.5mL浓硫酸。装上60cm的分馏柱和分水器,加热反应脱水,约4h脱水115~120mL,反应液温度达到130℃。继续加热至反应液温度155℃,并回收丁醇。而后冷至50℃,分批加入固体碳酸钠4g,中和硫酸,直至pH5~6。放置过夜,过滤,减压蒸馏,收集198~200℃/0.8~0.9kPa的馏分,得产品(1)460g,收率85%。 [1]
