- Preparation method of 11-cyanoundecanoic acid
-
The invention relates to a preparation method of 11-cyanoundecanoic acid. 1,1'-peroxidation dicyclohexylamine (PXA) is subjected to a self-decomposition reaction under the effect of a rare earth metalcompound and a free radical initiator, thus the 11-cyanoundecanoic acid is obtained in a high-selectivity mode, and the PXA is generated by cyclohexanone through oxyamination. According to the process line, raw materials are simple and easy to obtain, the disadvantages that an existing process is difficult to control under the high-temperature condition and low in reaction selectivity, and products are difficult to separate are avoided, and the simple and convenient method is provided for preparation of the 11-cyanoundecanoic acid.
