Process for reducing a halogenated metallic compound with a metallic reducing agent

Claim 1

A PROCESS COMPRISING REDUCING A HALOGENATED METALLIC COMPOUND WITH A REDUCING AGENT TO PRODUCT A SUBSTANTIALLY PURE REDUCTION PRODUCT WHICH IS FREE OF ANY TRACES OF SAID REDUCING AGENT, THE PROCESS INCLUDING THE STEPS OF REACTING IN AN ANHYDROUS LIQUID MEDIUM, A METAL SELECTED FROM THE GROUP CONSISTING OF AL, MG, ZN, AND THE ALLOYS OF ALUMINUM AND COPPER AND ALUMINUM AND BERYLLIUM WITH A HALOGENATED TRANSITION METALLIC COMPOUND SELECTED FORM THE GROUP CONSISTING OF TICL4, TIBR4, TIL4, VCL4, VOCL3, VOBR3, MOCL3, ZRCL4, MOBR4, MOF6, MOOF4, AND CRO2CL2 AT A TEMPERATURE BETWEEN 0 AND 200*C. TO REDUCE THE HALOGENATED COMPOUND TO A COMPOUND IN WHICH THE VALENCE OF THE METALLIC ATOM IS LOWERED, SAID METAL WHICH REDUCES THE HALOGENATED COMPOUND BEING PRESENT IN THE FORM OF COMPACT PIECES, THE SMALLEST DIMENSION OF WHICH IS BETWEEN 0.3 AND 30 MM., AND IN AN AMOUNT IN EXCESS OF AT LEAST 30 TIMES THE STOICHIOMETRIC QUANTITY, AND PROVIDING RELATIVE MOVEMENT BETWEEN THE METAL AND THE LIQUID MEDIUM TO CONTINUALLY RE-EXPOSE THE SURFACE OF THE METAL BY CLEANING THE SURFACE OF ANY COATING WHICH MAY BE FORMED THEREON, WHEREBY THE HALOGENATED COMPOUND IS REDUCED AND IS FREE OF ANY TRACES OF SAID REDUCING AGENT.
