Overview
Hydroxymethane, commonly known as methanol, is the simplest alcohol with the chemical formula CH3OH. It is a light, volatile, and flammable liquid with a distinctive odor. Methanol is produced industrially through the catalytic hydrogenation of carbon monoxide or from natural gas. Methanol is a key feedstock in the chemical industry, serving as a precursor to formaldehyde, acetic acid, and other derivatives. Its versatility and relatively low cost make it a staple in both industrial and laboratory settings. The 'national standard content' refers to methanol meeting specific purity and quality criteria set by regulatory bodies like China's GB/T standards.
Physical and Chemical Properties
Methanol is a colorless liquid at room temperature with a boiling point of 64.7°C and a melting point of -97.6°C. It has a density of 0.7918 g/cm³, making it less dense than water. Methanol is highly soluble in water and most organic solvents, which enhances its utility as a solvent. Chemically, methanol is polar and can participate in hydrogen bonding. It is a weak acid and can react with strong bases to form methoxide salts. Its flammability (flash point: 11°C) and toxicity are critical considerations in handling and storage.
Main Applications
Methanol's primary use is as a feedstock for producing formaldehyde, which is further used in resins, plastics, and adhesives. It is also a key component in the synthesis of acetic acid, methyl tert-butyl ether (MTBE), and biodiesel. In addition to chemical synthesis, methanol serves as a solvent in laboratories and industries. It is used as an antifreeze in pipelines and as a denaturant for ethanol. Emerging applications include fuel cells and renewable energy storage, where methanol acts as a hydrogen carrier.
Safety and Storage
Methanol is highly toxic if ingested, inhaled, or absorbed through the skin. Exposure can lead to blindness, organ damage, or death. Proper personal protective equipment (PPE), including gloves, goggles, and respirators, is essential when handling methanol. Storage requires cool, well-ventilated areas away from heat sources and open flames. Containers should be tightly sealed to prevent evaporation and contamination. Spills must be managed with absorbent materials and reported according to local regulations.
B2B Procurement Guide
When procuring methanol, buyers should prioritize suppliers with certifications like ISO 9001 and compliance with national standards (e.g., GB/T 338-2011 in China). Key factors include purity (typically 99.9% for industrial use), packaging (drums, IBCs, or bulk tanks), and logistics options. Price negotiations should account for volume discounts and market fluctuations. Long-term contracts may offer stability. Always request safety data sheets (SDS) and certificates of analysis (CoA) to verify quality and compliance.
