3. Main Uses: Used as an organic solvent in the production of resins, coatings, inks, paints, adhesives, and leather processes, replacing acetone, butanone, ethyl acetate, cyclopentane, etc. Also used as a foaming agent for polyurethane foam and as a component of thinners.
4. Production and Preparation Methods, Process: Esterification reaction of acetic acid with methanol.
5. Hazard Category: Category 3.2 Flammable liquid with medium flash point.
6. Firefighting Measures: Use alcohol-resistant foam, carbon dioxide, dry powder, or sand to extinguish fires. Water is ineffective for extinguishing but can be used to cool containers in the fire.
7. First Aid Treatment: Remove contaminated clothing and thoroughly rinse the skin with soap and water. Gastric lavage with 4% sodium bicarbonate can be performed. Do not pour into drains. Prevent static electricity buildup; highly flammable.
8. Packaging, Storage, and Transportation: Packed in steel drums, 180 kg/drum; store in a cool, well-ventilated warehouse. Keep away from fire and heat sources. Warehouse temperature should not exceed 30°C. Keep containers sealed. Store separately from oxidizers, acids, and alkalis; avoid mixed storage. Use explosion-proof lighting and ventilation facilities. Avoid using mechanical equipment and tools that may generate sparks. The storage area should be equipped with leak emergency handling equipment and suitable containment materials. Transport during early morning or evening in summer. Tankers used for transportation should be equipped with grounding chains, and baffles can be installed inside the tank to reduce static electricity generated by agitation. Do not transport or mix with oxidizers, acids, alkalis, food chemicals, etc.
