PROCESS FOR PREPARING DIALKYL DISULPHIDES

摘要

The present invention relates to a process for obtaining dialkyl disulphides from an alkyl mercaptan and a sulphur, in which a reaction intermediate present in the final disulphide is decomposed at the end of synthesis. This operation makes it possible to avoid the degradation over time of said reaction intermediate which is responsible for the decrease in purity of the dialkyl disulphide.
