2-Methyl-2-propanol[2]
Overview
2-Methyl-2-propanol, commonly referred to as tert-Butyl alcohol (TBA), is a tertiary alcohol with the chemical formula C4H10O. It is a clear, colorless liquid with a distinct camphor-like odor. TBA is widely utilized in various industrial applications due to its solvent properties and role as an intermediate in organic synthesis. TBA is produced through the hydration of isobutene or as a byproduct in the production of propylene oxide. Its unique chemical structure, featuring a central carbon atom bonded to three methyl groups and a hydroxyl group, imparts specific reactivity and solubility characteristics.
Physical and Chemical Properties
2-Methyl-2-propanol exhibits several notable physical and chemical properties. It has a relatively low melting point of 25.5°C and a boiling point of 82.4°C, making it volatile at room temperature. The compound is miscible with water, ethanol, and ether, which enhances its utility as a solvent. Chemically, TBA is highly flammable and reactive. Its tertiary alcohol structure makes it less prone to oxidation compared to primary and secondary alcohols. However, it can undergo dehydration to form isobutene under acidic conditions. These properties are critical for its applications in industrial processes.
Main Applications
2-Methyl-2-propanol serves as a versatile solvent in the production of paints, coatings, and adhesives. Its ability to dissolve a wide range of organic compounds makes it valuable in laboratories and manufacturing processes. Additionally, TBA is used as an intermediate in the synthesis of other chemicals, such as methyl tert-butyl ether (MTBE), a fuel additive. It also acts as a denaturant for ethanol, rendering it unsuitable for consumption while preserving its industrial utility. The compound's applications extend to pharmaceuticals and agrochemicals, where it functions as a reagent or solvent.
Safety and Storage
Handling 2-Methyl-2-propanol requires strict adherence to safety protocols. The compound is highly flammable, and its vapors can form explosive mixtures with air. Proper ventilation and the use of explosion-proof equipment are essential in workplaces where TBA is used or stored. Storage conditions should include cool, dry, and well-ventilated areas, away from direct sunlight and ignition sources. Containers must be tightly sealed to prevent evaporation and contamination. Personal protective equipment (PPE), such as gloves and goggles, should be worn to minimize exposure risks.
B2B Procurement Guide
When procuring 2-Methyl-2-propanol, B2B buyers should prioritize suppliers with a proven track record of quality and compliance. Verify the CAS number (75-65-0) and ensure the product meets the required purity specifications, typically 99% or higher for industrial use. Consider logistical factors such as packaging options (bulk, drums, or smaller containers) and transportation regulations, given the compound's flammability. Pricing varies based on quantity and market conditions, with reference prices ranging from $1.50 to $3.00 per kg. Establish long-term contracts to secure stable supply and favorable terms.
