Uses Main Uses: Dimethylformamide (DMF) is an important chemical raw material and a solvent with excellent performance. It is also an important intermediate in organic synthesis. It can be used to produce dimethamidine in the pesticide industry; it can be used to synthesize iodosamine in the pharmaceutical industry. , Doxycycline, Cortisone, Vitamin B6, etc. Dimethylformamide also has a catalytic effect, which reduces the reaction temperature and improves the purity of the product. Although it is a "universal solvent".
Hazard category Class 3.3 flammable liquid
Fire-fighting measures Use capacity-resistant foam, carbon dioxide, dry powder, sand to extinguish the fire, and water can be used to keep the container cool when it is critical.
Emergency treatment Low toxicity. If splashed on clothes and skin, take off clothes, rinse skin with water, splash into eyes, lift eyelids and rinse with running water or saline for 15 minutes. If inhaled, leave the scene to fresh air, oxygen, Artificial respiration, seek medical advice; if swallowed, induce vomiting, seek medical advice.
Packaging, storage, transportation It can be packed in baking painted iron drum (190kg/drum), plastic drums (190kg/drum) and stainless steel pressure tank; it should be stored in a cool, ventilated warehouse, protected from light, heat insulation, and sealed drums. The shelf life is one year. The storage effect of pressure tank is not as good as barreled, and it is not suitable for long-term storage; transportation according to the requirements of dangerous goods.
