摘要:
Cyclohexylamine is produced by the catalytic hydrogenation of aniline. In contact with a ruthenium catalyst and in the presence of from about one to about 8 parts by weight of ammonia, aniline is hydrogenated under an absolute pressure of from about 2 to about 5 MPa at a temperature of from about 160.degree. to about 180.degree. C. High yields and a minimum of byproducts result. The catalyst can be recycled.
摘要:
The present invention provides novel cycloalkylmethylamine derivatives, and methods of preparing cycloalkylmethylamine derivatives. The present invention also provides methods of using cycloalkylmethylamine derivatives and compositions of cycloalkylmethylamine derivatives. The pharmaceutical compositions of the compounds of the present invention can be advantageously used for treating and/or preventing obesity and obesity related co-morbid indications and depression and depression related co-morbid indications.

摘要:
Improved Group 8-10 transition metal based supported catalyst processes for the polymerization of olefins are described. Some of the improvements pertain to protocols for catalyst preparation and activation which improve the catalyst productivity in the presence of hydrogen as a molecular weight control agent.
