Thiazole derivatives as vulcanization accelerators. II-IV was written by Kimijima, Takuzo;Miyama, Shunichi. And the article was included in Kogyo Kagaku Zasshi in 1943.Product Details of 1843-21-6 This article mentions the following:
Equivalent amounts of PhNH2, CS2, and S were made to react in an autoclave under pressure at 180-260° for 6 hrs. to obtain mercaptobenzothiazole, with the pressure varying from 20 to 50 atm. according to the temperature used. Analysis showed that at 180° the reaction was incomplete, the product being mostly anilinobenzothiazole with a large amount of aniline left unreacted. Yields of mercaptobenzothiazole at 200, 220, 240, and 260° of 13.3, 86.5, 76.4, and 67.6%, resp., were obtained. From the reaction products at various temperatures, it was deduced that mercaptobenzothiazole is formed through anilinobenzothiazole and that the reaction is endothermic. In the experiment, the researchers used many compounds, for example, N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6Product Details of 1843-21-6).
N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6) belongs to thiazole derivatives. Thiazole is a five-membered, unsaturated, planar, π-excessive heteroaromatic containing one sulfur atom and one pyridine-type nitrogen atom at position 3 of the cyclic ring system. Electrophilic attack at nitrogen depends on the presence of electron density at nitrogen as well as the position and nature of substituent linked to the thiazole ring.Product Details of 1843-21-6
