The product we are introducing here is 2-Mercaptobenzoxazole with the CAS number 2382-96-9. It is factory - supplied and comes with a low price, making it an attractive option for various industries. This chemical compound has a specific molecular formula and weight. The molecular formula of 2 - Mercaptobenzoxazole is (C_{7}H_{5}NOS), and its molecular weight is approximately 151.19 g/mol. It usually appears as a white to light - yellow crystalline powder. The melting point of 2 - Mercaptobenzoxazole is in the range of 198 - 201°C. It is sparingly soluble in water but soluble in organic solvents such as ethanol, acetone, and chloroform.
2 - Mercaptobenzoxazole has a wide range of applications in different fields. In the rubber industry, it is used as a vulcanization accelerator. It can significantly improve the vulcanization efficiency of rubber, enhance the physical properties of rubber products such as tensile strength, hardness, and abrasion resistance. This helps to produce high - quality rubber products like tires, rubber seals, and conveyor belts. In the field of metal corrosion protection, it can act as a corrosion inhibitor. It forms a protective film on the metal surface, preventing metal from being corroded by environmental factors such as moisture and oxygen. In the pharmaceutical industry, it can be used as an intermediate for the synthesis of certain drugs. Some drugs with anti - inflammatory and antibacterial properties may use 2 - Mercaptobenzoxazole in their synthesis process.
When using 2 - Mercaptobenzoxazole in the rubber industry, it is necessary to determine the appropriate dosage according to the type of rubber and the specific requirements of the product. Usually, the dosage ranges from 0.5 to 2 phr (parts per hundred of rubber). It should be added during the rubber mixing process, and uniform mixing is crucial to ensure its effectiveness. When used as a corrosion inhibitor, the compound can be dissolved in a suitable organic solvent to form a solution. The metal surface should be cleaned and degreased first, and then the solution can be applied to the metal surface by spraying, brushing, or dipping methods. In the pharmaceutical synthesis process, strict operating procedures and reaction conditions should be followed. Appropriate reaction solvents, catalysts, and reaction temperatures should be selected according to the specific synthesis route.
Case 1: Rubber Tire Production
A tire manufacturing company used 2 - Mercaptobenzoxazole as a vulcanization accelerator. They added 1.2 phr of the product during the rubber mixing process. After vulcanization, the tires showed significantly improved properties. The tensile strength increased from 18 MPa to 22 MPa, and the abrasion resistance improved by 15%. This led to longer - lasting tires with better performance on the road, resulting in higher customer satisfaction and increased market competitiveness for the company.
Case 2: Metal Pipe Corrosion Protection
A pipeline construction company needed to protect metal pipes from corrosion in a humid environment. They prepared a solution of 2 - Mercaptobenzoxazole in acetone and applied it to the pipes by dipping. After a one - year field test, the pipes treated with the solution showed only slight surface corrosion, while the untreated pipes had severe rusting. This demonstrated the excellent corrosion - inhibiting effect of 2 - Mercaptobenzoxazole.
Case 3: Pharmaceutical Synthesis
A pharmaceutical research and development company used 2 - Mercaptobenzoxazole as an intermediate in the synthesis of a new anti - inflammatory drug. By following a specific reaction route with strict control of reaction conditions, they successfully synthesized the target drug with a high yield. The new drug showed promising results in pre - clinical trials, indicating the important role of 2 - Mercaptobenzoxazole in pharmaceutical synthesis.
