我国DSD酸溶剂法氧化合成工艺工业化解脱瓶颈制约的建议

介绍了国内有关单位用溶剂法氧化合成DSD酸的清洁生产工艺研究进展,分析了该工艺目前还未能用于工业化生产的原因:①工业化生产的一些工程技术难题还有待解决;②溶剂法工艺生产的总成本高于传统的水法工艺;③不少地区的环保执法存在"盲区",地方保护痼疾难除;④政策支持力度不够,企业缺乏积极性;⑤产能过剩竞相降价,企业无力承担科研费用。讨论了溶剂法氧化合成DSD酸工业化的瓶颈制约所在,指出了解决途径,提出了发展建议。

Some advice about breaking bottleneck in industrialization of oxidization technique for producing DSD acid in solvent

The progress in clean process of oxidization technique for producing DSD acid in solvent in some certain plants in China is introduced. The reasons that the process can not be industrialized yet are analyzed as follows: (1) some difficult problems in industrializing engineering haven't been resolved; (2) the total cost of solvent process is higher than conventional hydro-process; (3) many regions have vacuum area of executing the environment protection laws because of " regional protectionism" ; (4) enterprises are inactive to implement the solvent process for the reasons of policy; (5) the price of the product is cut over and over again for the surplus and enterprises are not able to afford the expense of research. The bottleneck in industrialization of oxidization technique for producing DSD acid in solvent is discussed, the ways of resolving it are pointed out and some suggestions are put forward.
