PROCESS FOR THE MANUFACTURE OF S-TRIAZINSULFENIMIDE

摘要

The sulfenamide (I; R1,R2,R3,R4 = H or C1-4 alkyl, Y = divalent hydrocarbyl, methyleneimino, ureylene group, X = R1R2N, imidothio) are scorch inhibitors for rubber vulcanization. Thus, addition of 6-(diethylamino)-2, 4-s-triazinedisulfenyl chloride (from 43.2g dimercaptan) in 250el phMe dropwise to 5, 5-dimethylhydantoin 53. 8, NaOH 16. 8, and H2O 250el and stirring at 0 - 5≦̸C for 30 min gave 72. 5g 2 (diethylamino)-4, 6-bis [(5, 5-dimethyl hydantoinyl)thio -s-triazine.
