Effects Of Biotechnology On Human Health, Particularly high rates of methane formation per unit of Cu mass were obtained for Cu electrodeposited on GO and PG supported on GC. Applications of Cannizzaro Reaction: Formation of Carboxylic Acid and Alcohol from aldehydes devoid of α-hydrogen. The Cannizzaro reaction is a redox reaction in which two molecules of an aldehyde are reacted to produce a primary alcohol and a carboxylic acid using a hydroxide base.. name Cannizzaro reaction. because of the Cannizzaro reaction . perspectives and avenues for further understanding the applications of the Cannizzaro reaction.

Tishchenko reaction A variant of the Cannizzaro reaction, known as the Tischenko reaction is a disproportionate reaction of an Aldehyde lacking a hydrogen atom in the alpha position in the presence of an Alcoxide. [3].We have been interested in the application of zeolites to organic reactions in the liquid phase and have reported that zeolites performed the shape-selective hydrolysis of esters [4] and ring-opening reaction of peroxides [5].
