12-TUNGSTOPHOSPHATES AS DEHYDROGENATION CATALYSTS DEHYDROGENATION OF MONOMETHYLAMINE TO HYDROGENCYANIDE
Authors: Niiyama Hiroo , Tamai Shoji , Saito Yoshinori , Echigoya Etsuro 
Published: July 2006

Abstract
Monomethylamine is dehydrogenated to yield hydrogencyanide by the catalysis of 12-tungstophosphates at temperature range of 400–500 °C. Simultaneous hydrogenolysis to yield methane and ammonia was also observed. Typical solid acid catalysts, such as Al2O3 or SiO2–Al2O3 have no activity for the reaction. Catalytic activity for the dehydrogenation might be ascribed to the affinity of polyanion to hydrogen atoms.
