Abstract: PURPOSE:To obtain 11-cyanoundecanoic acid, an intermediate for nylon 12, in high purity, by treating a thermal decomposition product of 1,1'-peroxydicyclohexylamine without effecting direct distillation under heating. CONSTITUTION:A reaction product, obtained by thermal decomposition of 1,1'- peroxydicyclohexylamine (PXA) at 300-1,000 deg.C, is treated with a mixed solvent of toluene and water, etc. and separated into an aqueous and an oil layers. epsilon- caprolactam (LC) is isolated from the aqueous layer, and ammonium salt of 11- cyanoundecanoic acid (CUA) is crystallized and isolated from the extract of the oil layer with aqueous ammonia. Cyclohexanone (ON) is isolated from the raffinate by distillation. Discoloration and impurity formation by direct heating can be prevented.
