Abstract

Alkali metal alcoholates suspended in an inert liquid hydrocarbon are obtained by reacting an alkali metal in the form of dispersed particles, having an average size not greater than 100 microns and suspended in an inert hydrocarbon medium with an alcohol. Suitable hydrocarbons are, for example, toluene, xylene, petroleum fractions, straight-run gasoline, kerosene, alkylate, mineral oil, octane, undecane, nonane and substituted naphthalenes. If desired, the alcohol may be premixed with an inert liquid hydrocarbon which may be the same as or different from the hydrocarbon in which the alkali metal is suspended. A dispersing agent may be added to the dispersion of alkali metal. Suitable dispersing agents are fatty acids, activated carbon or clay, and charcoal. The process is suitable for the preparation of alcoholates of alcohols such as methyl, ethyl, propyl, isopropyl, n-butyl, sec.-butyl, tert.-butyl, amyl, hexyl, octyl, decyl, benzyl and xylyl alcohols as well as higher alcohols such as lauryl alcohol, tridecanol, myristyl alcohol, cetyl alcohol, stearyl alcohol, eicosanol and docosanol. It can also be used for forming the alcoholates of unsaturated alcohols such as oleyl, linoleyl, palmitoleyl and eleostearyl alcohols, phytol and ricinoleyl alcohol and of alcohols derived from naturally occurring fats and oils such as sugar cane oil, menhaden oil, cotton seed oil, peanut oil, olive oil, soya oil, tung oil and palm oil. In the examples (a) metallic sodium is dispersed in toluene and treated with ethyl alcohol to give sodium ethylate; (b) metallic sodium is dispersed in toluene and treated with a mixture of alcohols obtained from menhaden oil.
