应用领域
概述柠檬酸三丁酯(TBC)是一种良好的环保增塑剂、润滑剂。常温下为无毒、有果香味、無色透明油狀液体。沸点170℃(133.3Pa),闪点(开杯)185℃。溶于多数有机溶剂。挥发性小,与树脂的相容性好,增塑效率高,在欧美等国家允许用于食品包装和医疗卫生制品,以及儿童软质玩具、制药、医用制品、香精香料、化妆品制造等行业。可赋于制品良好的耐寒性、耐水性和抗霉性。树脂经本品增塑后呈现良好的透明性和低温绕曲性能,并在不同介质中具有低挥发性和低抽出性,热稳定性好,遇热不变色。用本品制备的润滑油具有良好的润滑性能。
用途用作气相色谱固定液、塑料的韧化剂、泡沫去除剂及硝酸纤维的溶剂
用途用于聚氯乙烯,聚乙烯共聚物和纤维素树脂的增塑剂。
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
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]
