1. Methanol is widely used as a basic organic chemical raw material and high quality fuel. Mainly used in fine chemical industry, plastics and other fields to produce formaldehyde, acetic acid, chloromethane, methylamine, dimethyl sulfate and other organic products. Methanol can be used as a new clean fuel after further processing or can be added to gasoline for mixing.

4. Production and preparation method and process: pressurized catalytic hydrogenation of carbon monoxide

5. Hazard category: class 3.2 flammable liquids

6, fire measures: warehouse: ventilation, low temperature and dry; Store separately from oxidants and acids. Use soluble foam, dry powder, carbon dioxide and sand to extinguish fire.

7. First aid treatment: inhalation: leave the scene quickly to the fresh air. Keep respiratory tract open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Go to a doctor. Ingestion: drink enough warm water to induce vomiting. Wash stomach with water or 1% sodium thiosulfate solution. Go to a doctor. Skin contact: remove contaminated clothing and rinse thoroughly with soap and water. Eye contact: lift eyelid and rinse with flowing water or normal saline. Go to a doctor.

8. Packaging, storage and transportation: it can be packaged in iron drum with baking paint, 160KG/ drum. It can be stored in a cool and well-ventilated special storage room, away from ignition and heat source. Storage temperature should not exceed 37℃, keep the container sealed; It should be stored separately with oxidants, acids and alkali metals. Adopt explosion-proof lighting and ventilation facilities; Prohibit the use of mechanical equipment and tools prone to spark; The storage area shall be equipped with emergency leakage treatment equipment and appropriate storage materials. High temperature season should be transported in the morning and evening.
