Abstract: Production of organometallic compounds of sodium and potassium with alkylaromatic hydrocarbons (X) by reaction of the metal with a monochloride of a hydrocarbon (Y) and reaction of the organometallic compound formed with the alkylaromatic hydrocarbon (X). A fine dispersion of the metal in the alkylaromatic hydrocarbon (X) is first prepared by stirring a mixture of molten metal and hydrocarbon (X) in the presence of a dispersing agent; then the monochloride of the hydrocarbon (Y) is slowly added. The sodium or potassium compounds may be used for organometallic reactions or as monofunctional polymerization catalysts.
