摘要
Abstract
Maleic anhydride has poor stability at high temperatures and darkens in color.Through the analysis of the composition of maleic an-hydride,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.关键词
