用原位红外方法研究了苯甲川九羰基三钴对氨羰化反应的催化机理．分别考察了不同介质以及反应条件下，该催化剂随温度升高的分解情况．并将反应条件下其红外谱图随温度变化的结果与八羰基二钴催化下红外谱图进行了比较．发现一个新催化剂中间体．根据实验结果，提出了反应机理．
In situ infrared method was used to study the catalytic mechanism of benzracetamododecane tricarbonyl for ammonia carbonylation. The decomposition of the catalyst with increasing temperature was investigated under different media and reaction conditions respectively. The infrared spectra of the infrared spectra under the reaction conditions were compared with those of the dicobalt octacarbonyl catalyzed infrared spectra. Found a new catalyst intermediate. According to the experimental results, the reaction mechanism is proposed.
