N-Cyclohexyl-2-benzothiazolesulfenamide Chemical Properties,Usage,Production

Description

N-Cyclohexyl-2-benzothiazolesulfenamide is a rubber accelerator chemical. The most frequent occupational categories are metal industry, homemakers, health services and laboratories, and building industries.

Uses

N-Cyclohexylbenzo[d]thiazole-2-sulfonamide is useful for the production of sulfur-modified chloroprene rubber.

Definition

N-Cyclohexyl-2-benzothiazolesulfenamide (CBS) is one of the important kinds of sulfenamide vulcanization accelerator, have an anti-incipient scorch and the big advantage of curingprocess rate fast two concurrently in natural rubber, butadiene-styrene rubber, butadiene rubber, isoprene rubber, it is particularly suited for the furnace black sizing material that alkalescence is higher, variable colour and pollution are slight, and volume of production and the consumption of the most external CBS account for the 50% of thiazoles sulfuration chemicals total amount. In recent years, along with China's radial development, the demand for accelerator CBS has also presented the longest trend.

Production Methods

The synthetic method of N-Cyclohexyl-2-benzothiazolesulfenamide (CBS) mainly has sodium hypochlorite oxidization, Oxygen Catalytic Oxidation method, electrolytic oxidation, chlorine oxidation process, hydrogen peroxide oxidation method etc. at present, oxidizing process has raw material and is easy to get, the advantages such as equipment requirements is the highest. Product yield is high, and technique is simple and widely used by institute both at home and abroad. This method is to carry out condensation with 2-benzothiazolyl mercaptan (hereinafter referred to as M) in the presence of an oxidizer with cyclohexylamine to generate CBS.
