Hydrogenation microreactor chemical synthesis

A significant portion of the reaction steps in a typical fine chemical synthesis are catalytic hydrogenations, generally limited by resistances to mass and heat transport Large surface-to-volume ratios of microreactors would greatly benefit chemical... 

Recently, a new microreactor for the direct synthesis of hydrogen peroxide has been designed at the AIST, Tsukuba, and Mitsubishi Gas Chemical Inc., Tokyo. It operates at room temperature and IMPa. The reactor is made of glass and the catalyst is palladium on titania. The yield of 40% was reached, based on hydrogen, and the concentration was 10% [56]. 

Being thermodynamically stable nano-dispersions of water-in-oil or oil-in-water, microemulsions can be considered as microreactors to carry out chemical reactions and, in particular, to synthesize nanomaterials. Microemulsions thus have received much recent attention as media for synthesis of nanoparticles Pt, Pd, Rh, and Ir by reducing corresponding salts in the water micropools of w/o microemulsions with hydrazine or hydrogen gas and as media for polymerization to produce thermodynamically stable latexes in the nano-size range (<50 nm) not...
