N,N-Diethylformamide Usage

1. N,N-diethylformamide is a good solvent for a variety of polymers such as polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, etc., and can be used for wet spinning of synthetic fibers such as polyacrylonitrile fibers, and polyurethane Synthesis; used in plastic film making; also used as paint remover for removing paint; it can also dissolve some low-solubility pigments, giving the pigments the characteristics of dyes. Dimethylformamide is used for aromatic extraction and separation and recovery of butadiene from C4 fraction and isoprene from C5 fraction. It can also be used as an effective reagent for separating non-hydrocarbon components from paraffin. .

2. It has good selectivity for the solubility of isophthalic acid and terephthalic acid: the solubility of isophthalic acid in N,N-diethylformamide is greater than that of terephthalic acid, and it is used for solvent extraction in dicarboxylic acid formamide Or part of the crystallization can separate the two. In the petrochemical industry, N,N-diethylformamide can be used as a gas absorbent to separate and refine gas.

3. In organic reactions, N,N-diethylformamide is not only widely used as a solvent for the reaction, but also an important intermediate in organic synthesis. It can be used to produce insecticide in the pesticide industry.

4. Reagents for non-aqueous titration, solvents for vinyl resin and acetylene, organic synthesis, photometric determination, gas chromatography stationary liquid (maximum use temperature 50℃, solvent is methanol), separation and analysis of C2-C5 hydrocarbons, and can separate normal and isobutylene And cis, butene. Analysis of pesticide residues. Organic Synthesis. Synthesis of peptides. For the photographic industry.

5. An excellent solvent and chemical raw material with a wide range of uses. It is an excellent solvent for many polymers such as polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, etc. It can be used for wet spinning of synthetic fibers such as polyacrylonitrile fibers; synthesis of polyurethane; paint remover for removing paint; selective absorption of acetylene and separation and refining of butadiene; used as a solvent in the production of artificial leather; Used to synthesize insecticides; in the pharmaceutical industry, it can be used to synthesize iodosamine, doxycycline, cortisone, vitamin B6, iodoside, ququjing, pyrantel, N-formyllysin, and antitumor acid , Methoxychlor, chlorambucil, nitrosourea, furfurouracil, tranexamic acid, befenmethasone, megestrol, cholyvitamin, chlorpheniramine, etc.

6. Used as solvent and organic modifier in liquid chromatography, extractant and developing agent for thin layer chromatography, solvent for vinyl resin and acetylene, and solvent for non-aqueous solvent titration. And used in organic synthesis.

7. Mainly used as an industrial solvent, in the pharmaceutical industry for production, hormones, and also for the manufacture of insecticide.
