Method for preparing sulfenamide rubber vulcanization accelerator by heterogeneous catalysis of oxidation of molecular oxygen

The invention relates to a method for preparing a sulfenamide rubber vulcanization accelerator by heterogeneous catalysis of oxidation of molecular oxygen, and belongs to the field of chemical engineering. The method adopts heterogeneous metal cobalt-based nano material as a catalyst, in an oxygen or air environment, a sulfydryl compound and amine are reacted for 0.5-16 hours in an organic phase under the conditions that the atmospheric pressure is 1-7 and the temperature is 40-100 DEG C to prepare the sulfenamide rubber vulcanization accelerator. The catalyst has the characteristics of high catalytic activity, high reaction efficiency, low cost, easiness in obtaining and reusability; and the sulfenamide synthesis steps are simple, the conversion rate is high, byproducts are few, and the method is more suitable for industrial production.

Scalable electrochemical oxidant-and metal-free dehydrogenative coupling of S-H/N-H

A practical and scalable electrochemical oxidation of S-H and N-H was developed. This oxidant- and catalyst-free electrochemical process enables S-N bond formation with inexpensive nickel electrodes in an undivided cell. This procedure exhibits broad substrate scopes and good functional-group compatibility. A 50 g scale oxidative coupling augurs well for industrial applications.

Continuous preparation method of N-tert-butyl benzothiazole sulfenamide

The invention belongs to the technical field of refined chemical engineering and particularly relates to a continuous preparation method of N-tert-butyl benzothiazole sulfonamide (TBBS). By taking benzothiazole disulfide (a vulcanization accelerator DM), an organic solvent and tert-butylamine as raw materials and selecting an inorganic or organic alkaline catalyst, TBBS is synthesized in two continuous reactors; in the reaction process, an oxidant is not needed, and the added catalyst can be used repeatedly, the adding amount of the catalyst is 5-30% by weight of the added benzothiazole disulfide. According to a TBBS product synthesized by the method, the yield is stabilized in a range of 98-99.5%, methanol undissolved substance in the product is lower than 0.1%, in the process production,waste water is not generated, and the method is suitable for industrial production.
