| titleOfInvention | The method of catalytic molecular oxygen oxidation 2,2 '-two sulphur union II benzothiazoles of preparation in water phase |
| abstract | The present invention relates to catalytic molecular oxygen oxidation preparations 2 in a kind of water phase, the method of 2 '-two sulphur union II benzothiazoles, this method is using water-soluble transition metal phthalocyanine compound as catalyst, there is 2-mercaptobenzothiazole in oxygen or air environment in pressure 0.01-0.5 MPa, 40-100 DEG C of temperature and reacts 1-30 hours synthesis 2,2'-dithiodibenzothiazole under solvent condition.The reaction of preparation method of the present invention carries out in water phase, and without adding other organic solvents, catalyst activity is high, and reaction efficiency is high, it can repeatedly utilize, synthesis technology is simple and direct, and selectivity of product is high, and by-product is few, waste is few, environmental-friendly, has stronger prospects for commercial application. |
