DMF is an important organic material and good solvent. It is used as solvent for man-made leather and chemical fiber, also used as material for synthesis of insecticide of high-effectiveness and low-toxicity, as gas absorbent and purity the gas in petrochemical industry, as material of sulfadiazine, cortisone and vitamin B6 in pharmaceutical industry, and also as fixing agent in vapor-phase analysis.
1.DMF is widely used in the production and processing of polymers,Spinning solvent for polyacrylo nitrile fibreand polyurethane fibre (spandex) and processing solvent for production of polyurethane artificial and synthetic leather.
2.DMF is used for the separation and refining of acetylene from crude olefin gas.
3.DMF is used in extracting butadiene from the C4 distillate obtained by naptha cracking, etc.
and in separating isoprene from C5 distillate.
4. DMF is used as analytical reagent and solvent of ethylene resin and acetylene.
5. DMF is an excellent organic solvent, used as a solvent for polyurethane, polyacrylonitrile and polyvinyl chloride, as well as as a raw material for extraction, pharmaceutical and pesticide chlorphenamidine.
