Summary: | A preparation method of dicyclohexyl disulfide is provided, in which sodium disulfide is reacted with chlorocyclohexane in an aqueous solvent to synthesize dicyclohexyl disulfide, and in which at least a part of the reaction mixture containing by-produced sodium chloride is acidified to be acidic, and then neutralize it to recover sodium chloride. Furthermore, a preparation method of sodium chloride is also provided, in which at least a part of the reaction mixture containing sodium chloride synthesized by reacting sodium disulfide with chlorocyclohexane in an aqueous solvent is acidified to be acidic, and then neutralize it to recover sodium chloride.
Le procédé selon l'invention consiste à faire réagir du disulfure de sodium avec du chlorocyclohexane dans un solvant aqueux afin de synthétiser du disulfure de dicyclohexyle. Lors de ce procédé, une partie au moins du mélange réactionnel contenant du chlorure de sodium comme sous-produit est acidifiée, puis neutralisée afin de récupérer le chlorure de sodium. |
