马来酸制备
1、 苯氧化法纯苯经预热后,在钒系列催化剂作用下,经空气氧化生成顺丁烯二酸酐(以下简称顺酐),反应温度为360℃,然后经水吸收、浓缩、结晶和干燥得顺酸产品。
2、 丁烯(烷)氧化法丁烯(烷)在钒系催化剂作用下,经空气氧化生成顺酐,反应温度350-450℃,然后经水吸收生成顺酸,再经浓缩、干燥得成品。
3、 其他生产方法:(1)萘或邻二甲苯氧化生成苯酐时副产顺酸;(2)糠醛氧化法,此法因效益问题不被采用。
4.在乙酰氯的催化下,脱除苹果酸中的水,使成顺丁烯二酸酐,然后水解成马来酸:
5.制法:
于氢化装置中加入Lindlar Pd 催化剂100mg,2-丁炔酸(2)2g(0.0024mol),100mL乙醇,充分摇动使2-丁炔酸溶液。减压抽出空气,充入氮气,再抽出氮气,充入氢气,使氢气保持厂压,电磁搅拌下进行氢化。当吸收氢气达540mL后停止氢化。过滤,除去催化剂。减压蒸出溶剂,冷至15℃以下,析出白色固体顺式丁烯-2-酸(1)。用石油醚(40~60℃)重结晶,mp15℃。[1]
6.制法:
顺丁烯二酸酐(3):于装有搅拌器、回流冷凝器(连接氯化氢吸收装置)的反应瓶中,加入苹果酸(2)45g(0.33mol),慢慢加入乙酰氯57mL(0.835mol),搅拌下水浴慢慢加热,以使反应开始。反应中氯化氢气体生成,苹果酸慢慢溶解。当氯化氢逸出基本停止时,继续水浴加热2h。改为蒸馏装置,先蒸出低沸点的馏分,而后收集195~200℃的馏分,冷后固化。用氯化重结晶,得顺丁烯二酸酐(3)22g,收率67%。mp54℃。顺丁烯二酸(1):将上述化合物(3)22g加入12mL水,水浴加热。而后置于盛有浓硫酸的干燥器中以除去其中的水。最后几乎定量的得到顺丁烯二酸(1),mP143℃。对于大多数实验来说,产品已足够纯。可用丙酮-石油醚重结晶,mp144℃。
