IN PREPARING ORGANIC SULFIDES BY REACTING OLEFINS (E.G., BUTYLENES) WITH A SULFUR HALIDE TO FORM A SULFOHALOGENATED INTERMEDIATE WHICH IS SUBSEQUENTLY SULFURIZED AND DEHALOGENATED BY REACTION WITH AN AQUEOUS SOLUTION OF AN ALKALI METAL SULFIDE COMPOUND TO FORM A NONCORROSIVE ORGANIC SULFIDE PRODUCT OF HIGH SULFUR CONTENT, BLACKENING OF BOTH THE INTERMEDIATE AND THE FINAL PRODUCT IS PREVENTED BY INCORPORATING A SMALL AMOUNT OF A BASE (E.G., FORMAMIDE) EITHER IN THE SULFOHALOGENATION REACTION MIXTURE OR SHORTLY THEREAFTER IN THE INTERMEDIAE PRIOR TO THE SULFURIZATION-DEHALOGENATION REACTION. |
