Various heterocyclic compounds, namely, perhydro-4, 6-dimethyl-1-phenyl-2-thio-1, 3, 5-triazine, four urazole derivatives, 2-mercapto-5-phenyl-1, 3, 4-oxadiazole and three thiadiazole derivatives were prepared with an aim at the possible vulcanization accelerator. Mooney scorch test indicated that accelerating efficiency of perhydro-4, 6-dimethyl-1-phenyl-2-thio-1, 3, 5-triazine and bis (5-phenyl-1, 3, 4-thiadiazolyl- 2) disulfide is not inferior to that of the commercial accelerators. The other compounds prepared here did not show comparable effect to the commercial accelerators by judging from Mooney test, probably owing to their high melting points near or over 200°C and to their poor solubilities in rubber.
