METHOD FOR PREPARING 2,2'-DIMERCAPTODIETHYL- SULFIDE Russian patent published in 2004 - IPC

Abstract RU 2224745 C1

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method for preparing 2,2'-dimercaptodiethylsulfide that can be used for preparing ion-exchange resins and sorbents. Method involves treatment of nontoxic 1,2,5-trithiacycloheptane with potassium hydroxide an aqueous solution at heating. Proposed method provides carrying out the preparing 2,2'-dimercaptodiethylsulfide at temperature 90-100 C for 3-4 h with yield 75%. EFFECT: improved preparing method. 4 ex
