Introduction
Methanol is the simplest saturated monohydric alcohol, appearing as a colorless, transparent, highly volatile, and highly flammable liquid with a mild alcoholic odor. It is extremely toxic; ingestion can lead to blindness or even death. Common chemical reactions: oxidized to formaldehyde with a catalyst; esterification with carboxylic acids; combusts to produce carbon dioxide and water.

Applications
- Chemical Raw Material: Primarily used to manufacture formaldehyde, acetic acid, chloromethane, and methylamine; a core basic chemical.
- Solvent: An excellent solvent used in paints, coatings, resins, and pharmaceutical synthesis processes.
- Alternative Fuel: Used as a clean fuel or fuel additive to increase the octane rating.
Storage
Must be stored in a cool, well-ventilated dedicated warehouse for flammable materials. Keep away from fire and heat sources; warehouse temperature should not exceed 30°C. Keep containers tightly sealed and store separately from oxidants, acids, and alkali metals.
Handling and Precautions
Classified as a highly flammable liquid and toxic substance. Open flames are strictly prohibited. Operations must be conducted in well-ventilated areas. Operators must wear gas masks, anti-static work clothes, and chemical safety goggles. Avoid inhaling vapors or skin contact.
Formula
Automotive Windshield Washer Fluid (Anti-freeze): Pure Water (60%) + Methanol (35%) + Surfactant (5%).
Function: Methanol acts as an antifreeze and polar solvent here. It significantly lowers the freezing point of the fluid (preventing freezing in winter) while effectively dissolving grease and dirt on the glass. It evaporates extremely quickly without leaving water marks.
Packaging
fiber drum or carton box, lined with PE bag, drums/IBCs. Customized packaging available upon request.
