Abstract: A method of producing an alkyl amine salt of thiocyanic acid having enhanced load-carrying properties when employed in synthetic ester lubricating oils comprising contacting an alkyl amine with ammonium thiocyanate or monoalkyl ammonium thiocyanate at an elevated temperature while continuously blowing the reaction mixture with an oxygen containing gas and recovering the formed alkyl ammonium thiocyanate salt, the oxygen containing gas being introduced into the reaction mixture in a total amount of between about 0.2 and 5.0 moles per equivalent weight of amine; and synthetic ester oil compositions containing a load-carrying additive amount of the alkyl ammonium thiocyanate prepared by said method.
