摘    要:邻二甲苯氧化生产苯酐过程中,除生成苯酐外还副产少量的顺酐,顺酐经水吸收变成顺丁烯二酸水溶液,然后经过精制、异构化变成富马酸,这一回收工艺既简单又适用,但收率低,产品质量较差,并伴有二次污染,为解决这些问题,研究开发了一种新工艺,对过去的老工艺进行了改造,产品质量大大提高,原料消耗及污水排放量大大降低,经济效益明显。

关 键 词:苯酐 顺酐 富马酸 异构化 洗涤酸水 顺丁烯二酸

Abstract:A new process to produce fumaric acid from washing acidic water containing cis -butenoldicarboxylic acid formed during the manufacture of phthalic anhydride was developed with im-proved quality, decreased comsumption of raw material ,decreased discharge of waste water,and in-creased economic benefit.
Keywords:fumaric acid   recovery   phthalic anhydride
