ABSTRACT:
Formate salts of nitrogenous bases containing tertiary nitrogen are prepared by reacting the nitrogenous base with carbon dioxide and hydrogen using a soluble transition metal catalyst. For example triethylamine is reacted with carbon dioxide and hydrogen using ruthenium trichloride as catalyst and an isopropanol/water mixture as solvent to yield triethylammonium formate which was separated from the reaction mixture by distillation.
