【Abstract】 Since maleic anhydride is an important material to organic chemical industry, its recovery techniques are reviewed systematically. Developments of partial condensation and water absorption are introduced as well as organic solvents absorptionusing dialkyl phthalates, cycloaliphatic dialkyl esters and alcohols in detail. Considering the main maleic anhydride recovery teclniques being widely used nowadays, several developing trends, which may be helpful for further development of the maleic anhydride industry of our country, are presented for reference in the article.更多还原
