MBT is pale yellow monoclinic needles or flake crystals with unpleasant odor. Insoluble in water and gasoline, soluble in ethanol, ether, acetone, ethyl acetate, benzene, chloroform and dilute lye.
As a general-purpose vulcanization accelerator, this product is widely used in various rubbers. Fast acceleration for natural rubber and synthetic rubbers usually vulcanized with sulfur. However, it needs to be activated by zinc oxide, fatty acid, etc. Often used in combination with other accelerator systems, such as dithiothiuram and tellurium dithiocarbamate, it can be used as an accelerator for butyl rubber; when used in combination with tribasic lead maleate, it can be used for light-colored water resistance 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 (C.I.Disperse Red 121) can be obtained.
