5. Grades and Standards
Methanol is classified into different grades based on its purity and intended application:
1. Industrial Grade: Used in fuel, solvents, and biodiesel production.
2. Lab Grade: For analytical and research purposes.
3. Pharmaceutical Grade: Meets strict purity requirements for use in medicine and drug synthesis.
Common specifications are standardized by organizations like:
ASTM: D1152 for methanol purity in industrial applications.
ISO Standards: For international compliance and quality.
6. Applications
Methanol is widely used in:
Chemical Industry: To produce formaldehyde, acetic acid, and other derivatives.
Energy Sector: As a fuel additive, biodiesel component, and hydrogen carrier for fuel cells.
Solvents: In paints, coatings, and cleaning products.
Automotive: Antifreeze and windshield washer fluids.
