ABSTRACT:
A method for obtaining dialkyl dithiodialkanoates in which mercaptoalkyl esters are contacted with a halogen in an inert hydrocarbon solvent to produce a heavy liquid phase of dialkyl dithiodialkanoate and a separate liquid phase of hydrocarbon solvent. These phases are easily separated into the product dialkyl dithiodialkanoate and hydrocarbon solvent which can be recycled without further treatment. In an embodiment of the invention the dialkyl dithiodialkanoate is further contacted with alkylene oxide to neutralize residual acidic by-products in the reaction mixture.
