Dimethyl formamide (DMF) is a kind of organic compounds, chemical formula for HCON (CH 3) 2, colorless transparent liquid, with water and most organic solvents miscibility.
Pure dimethylformamide has a special odor, industrial grade or deteriorated dimethylformamide has a fishy smell, because it contains the impurity of dimethylamine.
The name comes from the fact that it is a dimethyl substitute for formamide (an amide of formic acid), both of which are on the N (nitrogen) atom.
It is a common solvent for chemical reactions.
As the polarity of high boiling point (hydrophilic) aprotic solvents, it can promote the SN 2 reaction mechanism.
Dimethylformamide is made from methyl formate and dimethylamine.
Dimethylformamide in strong base such as sodium hydroxide or strong acid such as hydrochloric acid or sulfuric acid is not stable in the environment (especially in high temperature), and hydrolysis of formic acid and dimethyl amine, the equations for HCON (CH 3)2+ H 2O - (CH) 32 NH + HCOOH.

4.Usage
Use 1: Used as an analytical reagent and solvent for ethylene resin and acetylene.
Use 2: is an excellent organic solvent, used as a solvent of polyurethane, polyacrylonitrile, polyvinyl chloride, also used as an extraction agent, medicine and pesticide chlorphenamidine raw materials.
Use 3: Dimethylformamide is not only a kind of chemical raw material with a wide range of USES, but also a kind of excellent solvent with a wide range of USES.It can be used in the synthesis of wet spinning and polyurethane of polyacrylonitrile fiber and other synthetic fibers.
Used for plastic film making;Can also be used as a paint remover;It also dissolves certain pigments of low solubility, giving them the characteristic properties of dyes.
Dimethylformamide can be used for aromatics extraction and for the recovery of butadiene and isoprene from c-4 and C-5 fractions, and as an effective reagent for the separation of non-hydrocarbon components from paraffin.
It has a good selectivity for the solubility of m-phthalic acid and terephthalic acid: the solubility of m-phthalic acid in dimethylformamide is higher than that of terephthalic acid, and the two can be separated by solvent extraction or partial crystallization in dimethylformamide.
In the petrochemical industry, dimethylformamide can be used as a gas absorber for separating and refining gases.
In organic reactions, dimethylformamide is not only widely used as a solvent, but also an important intermediate in organic synthesis.
Chlorphenamidine can be produced in the pesticide industry;
In the pharmaceutical industry, it can be used to synthesize sulfadiazine, doxycycline, cortisone, vitamin B6, iodide, pinnet, thiacil, N-formyllysosarcoma, antinomine, methoxyl mustard, benzo mustard, cyclohexanilide, furofluorouracil, hemostatic cycloacid, medroxymethamine, medroprogestin, bvidatar, ormin, etc.
Dimethylformamide plays a catalytic role in hydrogenation, dehydrogenation, dehydration and dehalation of hydrogen, reducing the reaction temperature and increasing the purity of the product.
Use 4: Non-aqueous titration reagent, solvent for ethylene resin and acetylene, organic synthesis, photometric determination, fixed liquid for gas chromatography (maximum use temperature: 50ºC, solvent: methanol), separation and analysis of C2-C5 hydrocarbon, and separation of positive, isobutene -[1] and cis, reverse butene -[2].Analysis of pesticide residues.Organic synthesis.Synthesis of peptides.For the photographic industry.
5.Company profile and staff style
Qingdao Hisea Chem Co., Ltd is a famous chemical manufacture since 1996, located in Chemical Logistics Park of Qingdao port which is only 30 kilometers from the Qingdao port, and the traffic is very convenient.
Based on the oil refining chemical plant of CNPC and Sinopec which distributed around of China,we product Glacial acetic acid, Formic acid, Nitric acid and hydrogen peroxide,alcohol, isopropyl alcohol, and we produce sodium hydroxide,potassium hydroxide,sodium sulfide, potassium nitrate, potassium sulfate based on salt, potassium, magnesium, coal resources from the lop nurand the Qinghai lake .Reduplicating distillation the acids and the solvents and improving the product purity is to reach each field application, textile ,reagent and medical level etc. It is our top advantage to provide the high purity of products and make customized production according to the customer's requirements.
The workers load the goods at the factory.
The sales department is attending the chemical industry Fair in Shanghai.
