该项目位于江苏省镇江市新区国际化学工业园,由江苏正丹化学工业股份有限公司投资建设,碳九芳烃综合利用生产特种精细化学品的产业链--年产4万吨偏苯三酸酐。工艺流程:将偏三甲苯和醋酸以一定的比例混合,按一定的配比加入催化剂(醋酸钴、醋酸锰、四溴乙烷)。用泵将上述配比好的物料连续输送进入氧化反应器,通入相应体积的
The project is located in International Chemical Industrial Park, New District, Zhenjiang City, Jiangsu Province. It is invested and constructed by Jiangsu Zhengdan Chemical Industry Co., Ltd., and the industrial chain of special fine chemicals with comprehensive utilization of carbon-9 aromatics - annual output of 40,000 tons of trimellitic anhydride. Process: Meta-benzene and acetic acid in a certain proportion of mixing, according to a certain ratio of catalyst (cobalt acetate, manganese acetate, tetrabromoethane). The pump with a good ratio of the above material into the continuous oxidation reactor, access to the corresponding volume
