摘　　要：研究了传统蓖麻油裂解制备癸二酸的工艺流程,分析产生大量含盐含酚废水的原因.提出采用一步酸化法制备癸二酸的新工艺流程,考察了水用量对癸二酸收率的影响.结果表明,新工艺癸二酸收率与原工艺相同,而废水量为原工艺的1/4,产品质量符合国家标准,为彻底根治癸二酸生产污染创造了条件.The traditional preparation process of sebacic acid by cracking castor oil was studied and the reason of producing a large number of waste water containing salt and phenol was analyzed, a new technological process and new condition for preparing sebacic acid by one step acidification method was put forward and the effect of water dosage on yield of products was investigated. The results indicated that sebacic acid yield of the new process is the same as that of the original process,and the quality of products was in accord with the national standards, however the wastewater quantity was only about 1/4 of traditional method. It create conditions for pollution treatment of preparation of sebacic acid completely.
