Water → Acrylamide

Sample 1: A reaction tube made of SUS-27 stainless steel measuring 30 mm in inside diameter and 300 mm in length is filled with 390g (bulk volume: 220 ml) of cupric oxide tablets (manufactured by Nikki Kagaku KK). Then, reduction is carried out at 200° - 270°C by flowing hydrogen gas and nitrogen gas at the rates 200 and 400 ml/min respectively. By this, a reduced copper catalyst of percent reduction of 98%, as determined from the degree of decrease in quantity, is prepared. After this, acrylonitrile and water are continuously supplied to the reaction tube at the rates of 140 and 690 g/hr. respectively to carry out reaction at 120°C. At the same time, the reacting solution is circulated at a rate of 40 liters/hr. An acrylamide aqueous solution is obtained through this reaction, wherein the rate of conversion from acrylonitrile to acrylamide is 70%.
