Catalytic synthesis of acetone by direct hydration of acetylene

Abstract

Background: Replacing the cadmium–calcium phosphate catalyst with a zinc-containing catalyst makes it possible to obtain acetone in good yield with minor changes in technology. Aim: Study the kinetic laws of obtaining acetone by catalytic hydration. Materials and methods: Experiments on the catalytic hydration of acetylene and its derivatives in the gas phase were carried out in a reactor with a diameter of 25 mm, a height of 1000 mm, and made of stainless steel under stationary conditions. Results and discussions: In the reaction of hydration of acetylene and its derivatives, the use of (Fe2O3)x:(MoO3)y :(ZnO)z:(Mn2O3)k catalysts can be highly efficient and promising in production, obtaining high-quality products.
