Abstract

PURPOSE: To obtain the titled compound useful as a synthetic raw material for vitamin B1, etc. in high yield at a low cost, by the oxidative dehydrogenation of β-aminopropionitrile in the vapor phase with oxygen or a gas containing oxygen in the presence of a specific metallic oxide as a catalyst.
CONSTITUTION: β-Aminopropionitrile in the vapor phase is subjected to the oxidative dehydrogenation with oxygen or a gas containing the oxygen in the presence of a metallic oxide expressed by the formula (A is Fe, Cr, etc.; B is Ni, Co, Mn, etc.; C is alkali metal, alkaline earth metal, etc.; D is P, As, etc.; a is 0.1W24; b is 0W24; c is 0W2; d is 0W5; x is the number of oxygen atoms necessary for satisfying the valence of the metallic component contained in the catalyst) as a catalyst to give the aimed compound. The reaction temperature is usually 350W550°C, and the contact time of the raw material with the catalyst is 0.01W20sec. The method is advantageous due to no formation of maleonitrile and fumaronitrile as by-products which cannot be easily separated and purified.
