偏苯三酸酐(TMA)是有机合成工业的重要化工原料。世界上TMA的生产技术和贸易主要由BP-Amoco公司控制,意大利、比利时、日本、俄罗斯和中国等国也有生产。我国TMA的研究开发工作起步较晚,现有哈尔滨石油化工厂、濮阳有机化工厂、江阴长泾醋酐厂、博大化工有限公司4家生产,产品主要用于生产PVC耐热增塑剂、聚酯树脂、高级绝缘材料。本文对TMA的国内外市场进行了分析,指出我国该行业面临的问题,并提出了相关建议。
Trimellitic anhydride (TMA) is an important chemical raw material for the organic synthesis industry. The production technology and trade of TMA in the world is mainly controlled by BP-Amoco, and Italy, Belgium, Japan, Russia and China also have production. The TMA research and development work in China started late. The existing Harbin Petrochemical Plant, Liyang Organic Chemical Plant, Jiangyin Changchun Acetic Anhydride Plant, and Boda Chemical Industry Co., Ltd. 4 production. The products are mainly used to produce PVC heat-resistant plasticizers, poly Ester resin, advanced insulation material. This article analyzes the domestic and foreign markets of TMA, points out the problems facing the industry in China, and puts forward relevant recommendations.
