Overview
Butyl Methyl Tetrahydrofuran (BMTHF) is a versatile organic solvent widely used in industrial applications. It belongs to the tetrahydrofuran family, characterized by its cyclic ether structure. BMTHF is valued for its solvency power and relatively low volatility, making it suitable for formulations requiring stable performance. This compound is typically synthesized through catalytic hydrogenation or other organic synthesis methods. Its balanced properties between polar and non-polar characteristics allow it to dissolve a wide range of substances, from resins to oils.
Physical and Chemical Properties
BMTHF appears as a colorless to pale yellow liquid with a characteristic ether-like odor. It has a molecular weight of 142.24 g/mol and a density of approximately 0.85 g/cm³. The compound boils around 150-160°C, making it suitable for medium-temperature applications. Chemically, BMTHF is stable under normal conditions but can form explosive peroxides upon prolonged exposure to air. It shows good solubility in most organic solvents but is practically insoluble in water. These properties make it particularly useful in formulations where water resistance is required.
Main Applications
The primary use of BMTHF is as a solvent in industrial coatings and adhesives. Its ability to dissolve both polar and non-polar substances makes it valuable in formulating paints, varnishes, and specialty coatings. The chemical industry also utilizes BMTHF in cleaning agents for machinery and electronic components. Another significant application is in the production of specialty chemicals and pharmaceutical intermediates. Some manufacturers employ BMTHF as a reaction medium in organic synthesis due to its inertness under many reaction conditions.
Safety and Storage
BMTHF is classified as a flammable liquid and should be handled with appropriate precautions. Storage should be in tightly sealed containers placed in cool, well-ventilated areas away from ignition sources. The compound may cause eye and skin irritation upon contact. Special attention should be given to peroxide formation. Containers should be dated when opened and used within recommended timeframes. Proper personal protective equipment, including gloves and eye protection, should be worn when handling BMTHF. In case of spills, absorb with inert material and dispose of according to local regulations.
B2B Procurement Guide
When procuring BMTHF, buyers should prioritize suppliers with proper certifications and quality control measures. Technical specifications should include purity levels (typically 98% or higher) and water content. Bulk purchases in drums or totes often provide better pricing, but consider storage capabilities. Request material safety data sheets (MSDS) and certificates of analysis for each batch. Evaluate supplier reliability through references and industry reputation. For international shipments, verify compliance with transportation regulations for flammable liquids. Consider establishing long-term contracts with reputable suppliers to ensure consistent quality and supply.
