developed as an economical alternative to commercial, custom synthesis of 14C2-cis-DCE. The method uses 5,10,15,20-tetrakis-(4-carboxyphenyl) porphyrin cobalt(II) as a catalyst in the presence of titanium(III) citrate to convert 14C2-TCE to 14C2-cis-DCE as shown in Figure 1. A purge-and-trap technique was used to isolate 14C2-cis-DCE to provide a methanolic stock solution of high purity (97% cis-DCE). The
开发了一种从 14C2-
三氯乙烯 (14C2-TCE) 生产 14C2-cis-
1,2-二氯乙烯 (14C2-cis-DCE) 的协议,作为 14C2-cis-DCE 商业定制合成的经济替代方案。该方法使用5,10,15,20-四-(4-羧基苯基)
卟啉钴(II)作为催化剂,在
柠檬酸钛(III)存在下将14C2-TCE转化为14C2-顺式-DCE,如图1. 使用吹扫捕集技术分离 14C2-cis-DCE,以提供高纯度(97% cis-DCE)的
甲醇储备溶液。该过程的总14C2-顺式-DCE产率为约53%。版权所有 © 2005 John Wiley & Sons, Ltd.
