Introduction: Dimethylformamide is an organic solvent for vinylres ins and acetylene, butadiene and acid gases. Itcaused contact dermatitis in a technician at an epoxyresin manufacturers, and can provoke alcohol-inducedflushing in exposed subjects.
Storage
DMF should be used only in areas free of ignition sources, and quantities greater than 1 liter should be stored in tightly sealed metal containers in areas separate from oxidizers.
Usage
N,N-Dimethylformamide (DMF) is a clear liquid that has been widely used in industries as a solvent, an additive, or an intermediate because of its extensive miscibility with water and most common organic solvents.Dimethylformamide is primarily used as an industrial solvent.
Dimethylformamide (DMF) is a clear, colorless, hygroscopic liquid with a slight amine odor. The solvent properties of DMF are particularly attractive because of the high dielectric constant, the aprotic nature of the solvent, its wide liquid range and low volatility. It is frequently used for chemical reactions and other applications, which require a high solvency power. The product is known as a universal solvent. The high solubility of polyacrylonitrile in DMF, together with the good miscibility of DMF in water makes DMF the preferred solvent to produce acrylic fibers. Also, the spinning of polyurethane based elastomers is performed from DMF based solutions. Another significant application is the use of DMF as a solvent for polyurethane-based coatings on leather and artificial leather fabrics.
Application: It is used in the chemical industry as a solvent, an intermediate, and an additive; for example, in the production of pharmaceuticals, synthetic fibers, resins, agrochemicals, petrochemical industry etc.
