37859-42-0 - Introduction
It is an organic compound with the chemical formula of C8H7NOS. It is a white crystalline powder, soluble in some organic solvents.
It is widely used as an antioxidant and accelerator in the rubber industry. It can be used as a rubber antioxidant, which can improve the heat resistance and weather resistance of rubber products. In addition, it can also be used as dyes and intermediates in the synthesis.
The common method of preparing calcium is through the reaction of benzothiazole and formaldehyde. The specific steps include reacting benzothiazole and formaldehyde under alkaline conditions to form calcium, and purifying the final product by crystallization.
Regarding safety information, it has certain toxicity. It may be irritating to the skin, eyes and respiratory tract, so protective measures should be taken when exposed. When using or handling, it should follow the relevant safety procedures and be equipped with appropriate personal protective equipment, such as gloves, protective glasses, etc. During storage and transportation, contact with oxidizing agents and strong acids should be avoided to prevent dangerous reactions. In the event of inadvertent exposure or an accident, rinse the affected area immediately with plenty of water and seek medical help.
