The isomerization reaction of CH3S→CH2SH (R1), H2 elimination reaction of CH3S→HCS+H2 (R2) and the isomerization reaction of HCS→CSH (R3) have been studied by using the density functional theory.

The recoverits of gold electrowinning from dilute cyanide solutions is about 98% by means of using porous electrode, lowering vice reaction of H_2 and two stage electrolysis.

Deoxygenation in the synthesis of taxol

A New Approach to Selective Deoxygenation of Bile Acids;

For most reduction reactions concerned,dehalogenation occurred seriously in hydrogenation reaction.

Studies on Catalytic Hydrogenating Dehalogenation of Benzene Halide;

The mechanism and kinetics of dechlorination were studied in order to reduce dechlorination.

At ambient temperature and pressure, the natural and the enhanced reductive dechlorination of 4-chlorophenol (4-CP) in soils with zero-valent iron (ZVI) were investigated in the laboratory with isothermal incubation and gas chromatography mass spectrometry (GC-MS) as the primary analytical method.

In this laboratory study,the effects of zero valent iron(ZVI),noble metals modified ZVI,and other reaction controlling factors on the reductive dechlorination of hexachloroethane(HCE) were investigated under conditions of isothermal incubation.
