摘　　要：评述了间二甲苯法制偏苯三酸酐(TMA)技术的最新进展。介绍了由间二甲苯经一氧化碳甲酰化和芳香醛水溶剂空气氧化生产TMA的工艺过程及其催化剂,并与传统工艺作了比较。The recent advances in technology about synthesis of trimellitic anhydride (TMA) from m-xylene were reviewed. The processes and catalysts for TMA production from m-xylene by formylation with carbon monoxide and aromatic aldehyde oxidation with air in water solvent were introduced, and were compared with the conventional process.
