Abstract
PURPOSE: To effeceintly produce hydroycanic acid by ammoxidizing methanol in the presence of a high activity catalyst with superior wear resistance and selectivity prepared by supporting a compound oxide of W, Mo and alkali metal on silica.
CONSTITUTION: A compound oxide of W, Mo and alkali metal of the formula is supported on silica to prepare a catalyst. In the formula, x is pref. 0.5W0.8, Y is pref. 0.05W0.2 and A (alkali metal ) is one or more out of Na, K, Rb, etc. In the presence of the catalyst, CH3OH, NH3 and O2 -contg. gas are reacted at 300W 600, esp. 350W500°C under atmospheric press. Wseveral atm together with steam or an inert gas if desired. By the reaction, the following results are obtd.; a CH3OH reaction rate of 96.8%, a hydrocyanic acid selectivity of 96.2%, a hydrocyanic acid yield of 87.3%, a NH3 decomposition rate of 21% and a catalyst wear rate of 0.7%.
