Overview
m-Methyltoluene, commonly known as 3-methyltoluene or meta-xylene, is an aromatic hydrocarbon with significant industrial applications. It is a colorless liquid with a characteristic aromatic odor and is primarily used as a precursor in chemical synthesis. The compound is derived from petroleum refining and is a key intermediate in the production of various chemicals. As a volatile organic compound (VOC), m-methyltoluene is handled with care in industrial settings due to its flammability and potential health hazards. Its role in the manufacture of plastics, resins, and dyes makes it a valuable commodity in the chemical industry.
Physical and Chemical Properties
m-Methyltoluene exhibits typical properties of aromatic hydrocarbons, including low solubility in water and high solubility in organic solvents like ethanol and ether. Its boiling point of 139°C and melting point of -48°C make it suitable for various industrial processes requiring moderate temperatures. The compound's density of 0.864 g/cm³ and molecular weight of 106.17 g/mol are standard for its class. Its flammability and volatility necessitate strict handling protocols to prevent accidents. The aromatic nature of m-methyltoluene also makes it useful in reactions where benzene derivatives are required.
Main Applications
m-Methyltoluene is predominantly used in the production of plastics and resins, where it serves as a key intermediate. It is also employed in the synthesis of dyes and fragrances, leveraging its aromatic properties. Additionally, it acts as a solvent in various industrial applications due to its ability to dissolve many organic compounds. In the pharmaceutical industry, m-methyltoluene is sometimes used as a starting material for certain drug formulations. Its versatility and relatively low cost make it a popular choice in bulk chemical manufacturing. However, its use is regulated in some regions due to environmental and health concerns.
Safety and Storage
Due to its flammable nature, m-methyltoluene must be stored in a cool, dry, and well-ventilated area, away from open flames and heat sources. Proper grounding of containers is essential to prevent static discharge, which could ignite the vapor. Personal protective equipment (PPE), including gloves and goggles, should be worn when handling the chemical to avoid skin and eye irritation. In case of spills, absorbent materials should be used, and the area should be ventilated immediately. Disposal must comply with local environmental regulations to prevent contamination.
B2B Procurement Guide
When procuring m-methyltoluene, B2B buyers should prioritize suppliers with a proven track record of quality and compliance with safety standards. It is advisable to request certificates of analysis (COA) to verify purity and composition. Bulk purchases often come with cost benefits, but buyers should ensure that storage facilities meet safety requirements. Transportation should be arranged with carriers experienced in handling hazardous chemicals. Long-term contracts with reliable suppliers can help stabilize prices and ensure consistent supply.
