发明名称 Purification of 6-aminocapronitrile
摘要 Purification of 6-aminocapronitrile by heating a mixture containing same and THA and converting the THA to higher boiling compounds, and then distilling the 6-aminocapronitrile. The time required to convert the THA is reduced if an organic carbonyl compound is present in the mixture during heating.
