METHOD FOR CYCLIZING HYDROLYSIS OF AN AMINONITRILE COMPOUND INTO LACTAM

摘要

The invention concerns a method for cyclizing hydrolysis of an aminonitrile compound into a lactam in the presence of a catalyst. More particularly, it concerns a method for cyclizing hydrolysis of an aminonitrile compound in the presence of a macroporous particulate catalyst resulting from deposit/impregnation of an oxygen-containing compound on a macroporous support such as alumina. The invention is particularly useful for preparing epsilon -caprolactam by cyclizing hydrolysis of aminocapronitrile.
