介绍了顺酐的性质和用途以及国内外生产顺酐工艺路线的比较,同时建议在立足于苯法生产的基础上应逐渐向污染小、收率高的正丁烷法转化。另外,也对国内顺酐市场发展作了认真而又客观的预测。 This paper introduced the properties and uses of maleic anhydride and the comparison of the technological routes of maleic anhydride production both at home and abroad. At the same time, it was suggested that based on the production of benzene, it should be gradually transformed into n-butane with low pollution and high yield. In addition, the domestic maleic anhydride market has also made a serious and objective prediction.
