摘要
A monochloro-substituted aliphatic alcohol containing 3-8 carbon atoms, a copper compound and a zinc compound are added to maleic anhydride to prevent discoloration of the maleic anhydride. Deterioration of the quality of the maleic anhydride can be inhibited when it is stored for a long period of time or heat-melted.
