Process Promises Safer Lab Hydrogenations

摘要

RESEARCHERS AT The City College of New York(CCNY),New York City,have developed an approach that eliminates the need for compressed hydrogen gas in cylinders and the safety issues using them raises in hydrogenation applications.”Hydrogenation...relies on the use of a finely divided metal such as palladium,often supported on charcoal,”says Mahesh K.Lakshman,who led the research.”It also needs a source of hydrogen gas...Compressed hydrogen gas cylinders are not only expensive but they pose an extreme explosion and fire hazard.”Their research revealed that mixing two stable materials together in the presence of palladium on charcoal produces a mixture capable of hydrogenation,without requiring an external source of compressed hydrogen gas.An article in the journal Advanced Synthesis and Catalysis contains more detail.
