摘要
偏苯三酸酐的生产方法主要有偏三甲苯硝酸氧化法、偏三甲苯气相氧化法等 ,其应用范围很广 ,在国外的生产与销售均很成熟。国内偏苯三酸酐行业面临着生产企业少 ,装置规模小 ,生产工艺落后的问题 ,应采取措施加以改进 ,才能迎接国外企业的挑战。
The main production methods for trimellitic anhydride include the oxidation by nitric acid and oxidation in gas phase with unsmy-trimethylbenzene as raw material.This product has very wide applications,and its production and selling at abroad have matured.The domestic trimellitic anhydride industry has had such problems as few production enterprises,small plant scale,and backward production processes For meeting the challenges from foreign enterprises,it is necessary to take improvement measures
