摘要： A carboxylic acid of formula RCO.sub.2 H where R is a C.sub.1 to C.sub.10 aliphatic hydrocarbyl group is prepared by heating under substantially anhydrous conditions an ester of formic acid of formula HCO.sub.2 R where R is as defined above in the presence of carbon monoxide and an effective amount of a catalyst system comprising a Group VIII metal, a halide and a compound containing a quaternary Group V atom. The quaternary Group V atom can be formed in situ by adding a compound containing a trivalent nitrogen, phosphorus or arsenic atom quaternizable under the reaction conditions and a quaternizing agent. Acetic acid is prepared by heating methyl formate in the presence of a catalyst system containing a rhodium compound, an iodide and a quaternary nitrogen-containing heterocyclic base.

摘要： 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.

摘要： An integrated process for the production of formic acid from carbon dioxide and hydrogen. The process comprises for example, a reactor in which the formate salt of a nitrogenous base is produced together with subsequent purification and formic acid recovery stages. In the process described formic acid is recovered from the formate salt by using a base interchange reaction in which there is generated a thermally decomposable formate salt of a high boiling base. The high boiling base can be for example an imidazole and the nitrogenous base can be triethylamine.
