摘要:
Aliphatic, cycloaliphatic, heterocyclic aliphatic and aromatic amines are prepared in a liquid phase reaction under the influence of light energy in the presence of a specified ammonium halide photocatalyst whereby addition of N-H bonds from ammonia or a primary or secondary amine occurs across the double bond of an olefin.
摘要:
The process for preparing aliphatic and aromatic amines by reacting an olefin with either ammonia, a primary amine, or a secondary amine at elevated temperature in the presence of an ammonium halide catalyst, preferably a catalyst-promoter combination, is disclosed herein.
摘要:
Arsenic impurities are removed from anhydrous hydrogen fluoride by treating the hydrogen fluoride with elemental chlorine and anhydrous hydrogen chloride or a fluoride salt or both and then separating the purified anhydrous hydrogen fluoride, preferably by distillation, from the nonvolatile arsenic compounds.
摘要:
A highly efficient reductive amination process is disclosed wherein vaporous alkyl alcohol, ammonia and hydrogen are reacted to form alkyl amines at elevated temperature and pressure in the presence of a catalyst system comprising reduced cobalt dispersed on a porous support.
