Product application

Dimethylformamide is not only a very versatile chemical raw material, but also a very versatile good solvent. Used as a solvent for polyurethane, polyacrylonitrile, polyvinyl chloride analysis reagents, vinyl resins, and acetylene solvents, as well as raw materials for extractants, medicines, and pesticides. In the petrochemical industry, dimethylformamide can be used as a gas absorbent to separate and refine gas. In organic reactions, dimethylformamide is not only widely used as a solvent for the reaction, but also an important intermediate in organic synthesis.

Packaging and transportation

Packaging mark: flammable liquid. Packing method: (Ⅲ) type. Glass bottle outside wooden box, lined with non-combustible material or aluminum drum, galvanized iron drum.

Storage and transportation conditions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Lightly load and unload when handling to keep the package intact.

Emergency treatment

Quickly evacuate personnel from the contaminated area to a safe area, isolate them, and strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and fire protective clothing. Cut off the source of leakage as much as possible. Prevent entry into restricted spaces such as sewers and flood drains.

Small leakage: Use sand or other non-combustible materials to absorb or absorb. It can also be washed with a lot of water, and the washing water is diluted and put into the waste water system.

A large number of leaks: construct dikes or dig pits for storage; cover with foam to reduce steam disasters. Use explosion-proof pump to transfer to tank truck or special collector, recycle or transport to waste disposal site for disposal.
