THE USE OF ORGANOMETALLIC COMPOUNDS IN PURIFICATION OF MAGNESIUM, CALCIUM MERCURY, GALLIUM, RHENIUM AND NICKEL

摘要

Results of an experimental program devoted to the purification of metals by the use of organometallic compounds are described. Magnesium can be electrodeposited from ethylmagnesium hydride solutions but high purity has not been achieved. Organocalcium compounds are not suitable intermediates for calcium purification. Ultrapure mercury was prepared by decomposition of diethyl-mercury with ultraviolet light. Organogallium compounds did not yield gallium when exposed to ultraviolet light, and on thermal decomposition gave a product contaminated with carbon. High-purity rhenium was prepared from rhenium carbonyl by thermal decomposition. Exploratory experiments on nickel carbonyl pyrolysis were carried out.
