13351-73-0 - Introduction
1-methylbenzotriazole (1-methyl-1H-benzotriazole, commonly referred to as MTB) is an organic compound. Its chemical formula is C7H7N3 and its relative molecular mass is 133.15.
MTB is a colorless crystal or crystalline powder, with good stability, not easily soluble in water, soluble in organic solvents such as methanol, ethanol, chloroform, etc. It is a weakly basic compound that does not easily react with acids or bases under neutral conditions.
MTB has a wide range of applications. First of all, it is often used as a metal corrosion inhibitor and can be added to various metal lubricants, coolants and antifreeze to prevent metal damage due to corrosion. Secondly, MTB can also be used as an ultraviolet absorber, added to plastic products, coatings and paints to protect objects from ultraviolet damage. In addition, MTB is also used in the synthesis of dyes, photosensitive materials and fluorescent substances.
There are various methods for preparing MTB. A common method is to obtain m-nitrotoluene by nitrosation of toluene. Then, m-nitrotoluene is reacted with t-butyl ammonia under basic conditions to produce MTB. Specific reaction conditions and processes can be adjusted according to specific conditions.
When using MTB, you need to pay attention to its security information. It is less harmful to the human body and the environment, but it still needs proper safety operation. Avoid inhaling dust and avoid contact with skin and eyes. During operation, appropriate protective gloves and glasses should be worn to ensure a well-ventilated laboratory environment. When storing, MTB should be kept in a dry, cool place, away from fire and flammable materials. In case of accidental contact or inhalation, rinse immediately with water or seek medical attention.
