Abstract: A process for dehalogenating halogenated hydrocarbons is disclosed wherein after vacuum dewatering of the hydrocarbon it is admixed in a reaction vessel with a dispersion of sodium of particle sizes of 10 microns or less, heated above 97.7.degree. C. to liquify the sodium and the atmosphere above the admixture is converted to argon gas. Thereafter the admixture may be saturated with hydrogen by dissolution to facilitate the reaction. The reaction products are cooled, and the dehalogenated hydrocarbon is removed after filtration.
