乙酸异戊酯合成路线

乙酸异戊酯上下游产品

乙酸异戊酯制备

1.(1)由乙酸和异戊醇经酯化反应而得。在乙酸和戊醇混合液中,加入硫酸进行酯化反应,然后用碳酸钠(或苛性钠)中和,用氯化钙脱水而制得粗酯,再经蒸馏精制而得成品。 (2)流化催化精馏制备 ①在再沸器中加入醇酸混合液,硫酸与异戊醇的配比为3:1(摩尔比),加入109自制的改性离子交换树脂细粉,在分相器中加入一定量的水。 ②加热再沸器中溶液至沸腾。当塔顶有冷凝液时,保持全回流操作。当塔顶温度稳定后,调节回流比装置,使反应生成的水和酯全部从塔顶取出,进入分相器中分相,酯层作为粗酯产品取出,水相一部分从塔顶回流至塔中,并使塔顶温度保持不变。当不能用回流比调节装置保持原塔顶温度,且塔釜醋酸含量大于97%时,又改为全回流。 ③通过调压器逐步增加塔釜的供热量,直至塔中产生液泛,然后调小电流,保持塔釜的供热量,并在整个生产过程中保持不变。 ④待过程稳定后,以塔顶酯相中醋酸异戊酯含量和塔釜醋酸含量为控制指标,其中釜底液循环。 (3)将冰醋酸加入烧瓶中,然后加入硫酸和异戊醇,搅拌下加热回流,当分馏柱顶端温度达到132℃时即反应完全。然后进行粗蒸馏,收集分馏柱顶136-143℃的馏分即为粗酯。粗酯用饱和食盐水洗两次,用氢氧化钠、碳酸钠混合碱液中和酸,再用氯化钙干燥后,加入精馏装置进行精馏,收集138-143℃的馏分即为成品。 精制方法:除含有水、乙酸、异戊醇等杂质外,由于原料来源不同尚可含有丙醇、丁醇、己醇、庚醇及其乙酸酯等。精制时用碳酸氢钠或碳酸钠饱和溶液洗涤,再用氯化钠饱和水溶液洗涤,无水硫酸钠或硫酸镁干燥后精馏。 (4) 将硫酸及异戊醇加到冰醋酸中,加热回流,当分馏柱顶端温度达132℃时,即为反应完全。反应式如下: 蒸馏,收集136~143℃馏分为粗品,用饱和食盐水洗涤二次,用氢氧化钠、碳酸钠混合液洗去酸性,再用氯化钙溶液洗涤,用无水氯化钙干燥,最后进行分馏,收集138~143℃馏分即为成品。

2.制法:

于装有分水器的圆底烧瓶中,加入异物醇(2)44g(0.5mol),冰醋酸30g(0.5mol),一粒沸石。慢慢加热回流。随着反应的进行,分水器中的水层也逐渐增多。当下层水接近分水器的支管时,放出水层至量筒中。待约收集9mL时,停止反应。将反应液冷却,加入50mL水。分出有机层,用5%的碳酸氢钠水溶液反复洗涤,直至弱碱性。最后用饱和盐水洗涤。无水硫酸钠干燥。蒸馏,收集134~142℃的馏分,得乙酸异戊酯(1)51g,收率78%。
