摘　　要：偏苯三酸酐的生产方法有偏三甲苯液相硝酸氧化法、偏三甲苯气相空气氧化法、偏三甲苯液相空气氧化法和间二甲基苯甲醛液相空气氧化法 4种。目前世界偏苯三酸酐的总生产能力约为 2 3 0kt/a ,产量约为 165kt。 2 0 0 3年我国偏苯三酸酐的生产能力约为 41kt/a ,产量约为 16kt。预计到 2 0 0 5年我国偏苯三酸酐的消费量将达到 17 5kt ,生产能力已经严重过剩 。There are four processes to produce trimellitic anhydride, including nitric acid oxidation of asmy trimethylbenzene in liquid phase,air oxidation of asmy trimethylbenzene in gas phase,air oxidation of asmy trimethylbenzene in liquid phase and air oxidation of 1,3-dimethyl benzaldehyde in liquid phase. At present,the total production capacity of trimellitic anhydride in the world is about 230kt/a,with output of 165kt/a. In 2003, The production capacity of trimellitic anhydride in China was about 41kt/a,with output of 16kt/a and total consumption about 13.5kt/a。It was predicted that the total consumption of trimellitic anhydride in China was due to reach about 17.5kt in 2005.The production capacity has been serious oversupplied and the enlarging of trimellitic anhydride production capacity should be restricted.
