摘要：The invention relates to a method for the production of symmetric orasymmetric dialkyl disulphides using at least one mixture of symmetric and/or
asymmetric dialkyl disulphides in a photochemical and/or basic catalytic reaction, with thepreferably continuous joint extraction of the desired symmetric and/or asymmetricdisulphide(s). The method of the invention is particularly suitable for the production ofdimethyl disulphide or diethyl disulphide from a mixture of symmetric or asymmetricdialkyl disulphides.
