WebAliphatic primary amines have a carbon with sp 3 hybridization and two hydrogen atoms connected to the nitrogen atom. Pyrolysis of these compounds can take place with the involvement of the NH 2 group. In this case, there are two common paths, one with ammonia elimination and the formation of an unsaturated hydrocarbon (similar to water elimination … WebApr 11, 2013 · Copper nanoparticles dispersed rod-shaped La2O2CO3 efficiently catalyzed transfer dehydrogenation of primary aliphatic alcohols with an aldehyde yield of up to 97%. This high efficiency was achieved by creating a catalytically active nanoenvironment for effective reaction coupling between alcohol dehydrogenation and styrene hydrogenation … chinese number 0-10
