Abstract: Tetravalent titanium alcoholate-beta diketone complexes, e.g. titanium isopropylate-triacetylacetonate, are reacted with an alkali metal amalgam in a non-polar solvent to reduce the titanium to trivalent state, forming, for example, titanium triacetylacetonate and sodium isopropylate. The sodium isopropylate is a crystalline precipitate which can be removed by filtration; the amalgam can be decanted off and reused, as in alkali metal chloride electrolysis, to restore its alkali metal content so as to be ready for re-cycling.

Abstract: In a tubular reactor carrying a bed of solid material into which carbon electrodes project for heating the material upon passage of a current, the outside ends of said electrodes being connected to metallic conductors in turn connected to a supply of current, the invention involves pouring lead about the end of each electrode to effect improved contact between the electrode and its respective metallic conductor. The process involving use of such electrodes to react carbon with chlorine and the oxide of silicon or metals such as vanadium, titanium or zirconium is also covered.
