product description

Dimethylformamide is a flammable, colorlessliquid with a fishy, unpleasant, amine-like scent at relativelylow concentrations. The smell threshold is 0.47100 ppm.Molecular weight= 73.11; Specific gravity (H2O:1)= 0.95;Boiling factor = 153℃; Freezing/Melting factor = 261℃;Vapor pressure= three mmHg at 20℃; Flash factor = 58℃;Autoignition temperature= 444.5℃. Explosive limits are:LEL = 2.2%; UEL= 15.2% at 100℃. Hazard Identification(based on NFPA-704 M Rating System): Health 2,Flammability 2, Reactivity zero Soluble in water.Potential Exposure: Tumorigen,Mutagen; Reproductive Effector; Human Data; Hormone,Primary Irritant. DMFA is used as a solvent for liquids,gases, and as a fuel additive. Dimethylformamide haspowerful solvent homes for a broad vary of organiccompounds. Because of its bodily properties, this chemical has been used when solvents with a gradual price of evaporation are required. It finds unique utilization in themanufacture of polyacrylic fibers, butadiene, purified acetylene, pharmaceuticals, dyes, petroleum products, and otherorganic chemicals.

Product Usage

N,N-Dimethylformamide (DMF) is a versatile high-boiling solvent widely acclaimed as the "universal solvent" due to its exceptional solubility. Its primary application is in the synthetic fiber and resin industry, where it is used to spin polyacrylonitrile fibers and manufacture high-quality synthetic leather (PU). In the pharmaceutical sector, DMF is an indispensable reaction medium for synthesizing vitamins, hormones, and various antibiotics. Additionally, it plays a critical role in the electronics industry for cleaning precision components and in petrochemicals for the selective extraction of acetylene and butadiene.
