Method of purifying haloformates
Abstract
Abstract COVERS A METHOD OF PURIFYING HALOFORMATE. PATICULARLY COVERS A METHOD OF PREVENTING DECOMPOSITION OF HALOFORMATES DUE TO PRESENCE OF IRON CONTAMINATS BY CONTACTING THE HALOFORMATE WITH AN AQUEOUS ALKALI METAL HALIDE SOLUTION WHEREBY THE IRON CONTENT OF THE ORGANIC HALOFORMATE PHASE IS SUBSTANTIALLY REDUCED. THE RESULTANT AQUEOUS PHASE IS THEN SEPARATED FROM THE ORGANIC PHASE. IN AN ALTERNATE PROCEDURE AN ACIDIC HALOFORMATE SUCH AS AN ALKYL HALOFORMATE IS TREATED WITH AN ALKALI METAL BASE SUCH AS AN AQUEOUS SODIUM HYDROXIDE SOLUTION WHEREBY THE HALOFORMATE IS BOTH NEUTRALIZED AND AN ALKALI METAL HALIDE GENERATED WHICH EFFEDTS SUBSTANTIAL REDUCTION OF THE IRON CONTENT IN THE ORGANIC HALOFORMATE PHASE.
