English Name: 2-Mercaptobenzimidazole
CAS:583-39-1
Molecular formula: C7H6N2S
Molecular weight: 150.20100
Application:The materials used as natural rubber, synthetic rubber and latex diene antioxidant, can be used for polyethylene. It is one of the two antioxidant, antioxidant and other (such as DNP, AP and other non pollution.) and use, can obtain obvious synergistic effect. This product is easy to disperse in rubber, no color in the sun. A slight pollution. When used alone and like dosage is 1-1.5, when the amount of more than 2, will produce the blooming phenomenon. In latex foam rubber in the dosage is 0.5-1, the transparent rubber products in 0.5 phr. Because this product has a bitter taste, should not be used for rubber products in contact with food. 2- MERCAPTOBENZIMIDAZOLE is a new antileprotic drug in medicine, low toxicity than sulfone drugs, and the effects are bottom resistance, no accumulation. Can be used for sulfone drugs in patients. 2- - benzimidazole alkali metal salt solution and water soluble reactive zinc salt solution can be 2- mercaptobenzimidazoles zinc salts, namely antioxidant MBZ (C14H10N4S2Zn). This product is non-toxic.
Product performance: odorless, but bitter. Soluble in ethanol, acetone and ethyl acetate, insoluble in petroleum ether and methane dioxide, insoluble in carbon tetrachloride, benzene and water. It has good storage stability and is the second antioxidant without pollution.
