| titleOfInvention | Method of recovering halide values from carbonylation reaction mixtures |
| abstract | This invention is a process for the carbonylation of an organic halide to prepare a carbonyl-containing compound, and recovery of halogen values in a useful form which comprises n (a) contacting an organic halide with carbon monoxide and an esterifying agent, a primary or secondary amine, or hydrogen gas, in an inert organic solvent in the presence of a water-insoluble tertiary amine or pyridine ring-containing compound, and a catalytic amount of a Group VIII metal catalyst, under conditions such that an organic ester, amide or aldehyde is prepared and the halide generated in the process forms a salt with tertiary amine or pyridine compound wherein the halide is bromine or iodine; n (b) separating the organic ester, amide or aldehyde from the reaction mixture which contains the tertiary amine or pyridine compound-halide salt; n (c) contacting the reaction mixture containing the tertiary amine or pyridine compound-halide salt mixture with a concentrated aqueous solution of an alkali metal base or alkaline earth metal base under conditions such that an aqueous solution of an alkali metal halide or an alkaline earth metal halide and reaction solution containing the tertiary amine or pyridine compound is prepared; n (d) separating the aqueous solution from the reaction mixture; and n (e) contacting the aqueous solution containing the alkaline earth metal halide salt or alkali metal halide salt with chlorine under conditions such that an alkali metal chloride salt or alkaline earth metal chloride salt and elemental halide is prepared. |
