Abstract
Organohalides are dehalogenated by bringing an organohalide or a mixture of two or more organohalides into contact with an alkali hydroxide in an alcoholic solution and in the presence of a catalytically effective amount of a heterogeneous transfer hydrogenolysis catalyst. The process can be carried out at relatively low temperatures (50.degree.-150.degree. C.) and at low pressures. No added hydrogen is employed, in excess of that contained in the ambient atmosphere.
Claims12
A process for the dehalogenation of organohalides wherein an organohalide or a mixture of two or more organohalides is brought into contact with an alkali hydroxide in an alcoholic solution and in the presence of a catalytically effective amount of a heterogeneous transfer hydrogenolysis catalyst, the process being carried out without the introduction of gaseous hydrogen in excess of that contained in the ambient atmosphere.
A process for the purification and reclamation of fluids contaminated with organohalides, comprising contacting the fluid to be purified with a stoichiometric excess of an alkali hydroxide, with respect to the organohalide, in an alcoholic solution and in the presence of a catalytically effective amount of a heterogeneous transfer hydrogenolysis catalyst, the process being carried out without the introduction of gaseous hydrogen in excess of that contained in the ambient atmosphere.
