dimethylformamide (DMF) CAS68-12-2 with low price
Informação básica
Modelo: HCU-67
Descrição do produto
Product Description Product introduction
Dimethylformamide (DMF) is a common solvent for chemical reactions. Pure dimethylformamide is odorless, but industrial grade or metamorphic dimethylformamide is fishy, because it contains impurities in dimethylamine.Dimethylformamide is unstable (especially at high temperatures) in the presence of a strong base such as sodium hydroxide or a strong acid such as hydrochloric acid or sulfuric acid and is hydrolyzed to formic acid with dimethylamine.
Characteristic and superiority
Dimethylformamide is a high boiling polar (hydrophilic) aprotic solvent that promotes the SN2 reaction mechanism. Dimethylformamide in case of fire, high heat can cause combustion explosion. With concentrated sulfuric acid, fuming nitric acid violent reaction or even explosion
Application
1. Dimethyl formamide for a variety of high polymer such as polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, etc. are good solvents can be used for polyacrylonitrile fiber and other synthetic fibers, wet spinning, polyurethane Synthetic; for plastic film; Dimethylformamide is used for the extraction of aromatic hydrocarbons and for the separation and recovery of butadiene from the carbon fraction and separation of isoprene from the carbon fractions, and as an effective reagent for the separation of non-hydrocarbon components from paraffin The
2. It is a good selectivity for the solubility of isophthalic acid and terephthalic acid: the solubility of isophthalic acid in dimethylformamide is greater than that of terephthalic acid, and solvent extraction is carried out in formic acid formamide Or part of the crystal, the two can be separated. In the petrochemical industry, dimethylformamide can be used as a gas absorbent, used to separate and purify the gas.
3. In the organic reaction, dimethyl formamide is not only widely used as a solvent for the reaction, but also an important intermediate for organic synthesis. Pesticide industry can be used to produce chlordimeform.

Precautions of usage
1, skin contact: take off contaminated clothing, rinse with plenty of water, at least 15 minutes. Medical treatment. ,
2, eye contact: immediately lift the eyelid, with a large number of mobile water or saline thoroughly rinse for at least 15 minutes. Medical treatment.
3, inhalation: quickly from the scene to the fresh air (upper wind). Keep the airway open. If breathing is difficult, give oxygen. Such as breathing to stop, immediately artificial respiration. Medical treatment. ,
4, ingestion: drink plenty of warm water, vomiting, medical treatment. Oral poison must be completely gastric lavage.
5, fire fighting methods: fire extinguishing agent: mist water, anti-soluble foam, dry powder, carbon dioxide, sand. Move the container from the fire to the open as far as possible. Spray water to keep the fire container cool until the end of the fire.
