Description
2-Mercaptobenzothiazole is a chemical with the molecular formula C7H5NS2. Light yellow monoclinic needle-like or leaf-like crystals. Soluble in glacial acetic acid, soluble in alkali and carbonate solution, insoluble in water. Has a bitter taste and has an unpleasant odor.
Function
As a general-purpose vulcanization accelerator, this product is widely used in various rubbers. Vulcanization accelerator for natural rubber and synthetic rubbers usually vulcanized with sulfur. However, it needs to be activated by zinc oxide, fatty acid, etc. before use. Often used in combination with other accelerator systems, such as dithiothiuram and tellurium dithiocarbamate, it can be used as a vulcanization accelerator for butyl rubber; it can be used in combination with tribasic lead maleate for light color Water resistant chlorosulfonated polyethylene compound. It is often used in combination with dithiocarbamate in latex, and when used in combination with diethylamine diethyldithiocarbamate, it can be vulcanized at room temperature. The product is easy to disperse in rubber and does not pollute. However, due to its bitter taste, it is not suitable for use in food contact rubber products. Accelerator M is an intermediate of accelerators MZ, DM, NS, DIBS, CA, DZ, NOBS, MDB, etc., 2-mercaptobenzothiazole with 1-amino-4-nitroanthraquinone and potassium carbonate in dimethyl Reflux in formamide for 3h, the dye disperse brilliant red S-GL (CIDisperse Red 121) can be obtained.
This dye is used for dyeing polyester and its blended fabrics. When 2-mercaptobenzothiazole is used as an electroplating additive, it is also called an acid copper plating brightener M, and is used as a brightening agent for bright copper plating with copper sulfate as the main salt.
In addition, the product is also used to prepare pesticides and fungicides, nitrogen fertilizer synergists, cutting oils and lubricant additives, organic anti-ashing agents in photographic chemistry, metal corrosion inhibitors, etc. In addition, it is a reagent for chemical analysis. The product is low in toxicity and has an irritating effect on the skin and mucous membranes.
Used as a sensitive reagent and rubber accelerator for the determination of gold, bismuth, cadmium, cobalt, mercury, nickel, lead, thallium and zinc.
Mainly used in the manufacture of tires, inner tubes, tapes, rubber shoes and other industrial rubber products.
This product is one of the effective corrosion inhibitors for copper or copper alloy. When the cooling system contains copper equipment and raw water contains a certain amount of copper ions, this product can be added to prevent copper corrosion.
2-Mercaptobenzothiazole is an intermediate of the herbicide fenthiofen, as well as a rubber accelerator and its intermediate.
Mainly used as brightener for bright copper sulfate. Has a good leveling effect. The general dosage is 0.05～0.10 g/L. It can also be used as a brightener for cyanide silver plating. After adding 0.5 g/L, the polarizability of the cathode is increased, and the crystals of silver ions are oriented and arranged to form a bright silver-plating layer.
