摘　　要：顺丁烯二酸酐高温下稳定性差,颜色变深。通过顺酐成分的解析,针对顺酐产品中发色基团的杂质进行化学处理,消除了其影响,使得顺酐在高温(140℃)下加热2 h后的色号由原来的200下降到50。Maleic anhydride has poor stability at high temperatures and darkens in color.Through the analysis of the composition of maleic anhydride,chemical treatment for impurities in the color-emitting groups in maleic anhydride products,eliminating their effects,so that the color number of maleic anhydride after heating at high temperature(140 ℃) for 2 hours from the original 200 down to 50.
