N,N-dimethylformamide (DMF) is an important raw material for chemical production and has a wide range of applications. This article will detail the properties and uses of DMF.

1. Properties

1. Physical Properties

DMF is a colorless transparent liquid with a slight amine odor. Its molecular formula is C3H7NO and its relative molecular mass is 73.09. DMF has a high boiling point of 152.8 ° C, so it has good thermal stability. In addition, DMF has good solubility and polarity, and can dissolve many organic and inorganic compounds.

2. chemical properties

DMF has strong reactivity and can react with many compounds. For example, it can react with acids, bases, aldehydes, ketones, esters and other compounds to generate corresponding derivatives. In addition, DMF can also be subjected to redox reaction, polymerization reaction, and the like.

2. USES

1. Solvent

Because DMF has good solubility and polarity, it is widely used as a solvent. It can dissolve many organic and inorganic compounds, so it is used to prepare coatings, inks, adhesives, synthetic fibers, etc.

2. Chemical raw material

DMF can be used as a chemical raw material for the production of many important compounds. For example, it can react with formaldehyde to generate dimethyl formal; react with aniline to generate N,N-dimethylaniline, etc.

3. pesticide intermediates

DMF can also be used as pesticide intermediates for the production of pesticides, fungicides and other pesticide products. For example, it can react with methyl chloride to produce dimethylformamide sulfoxide, which is an effective insecticide.

4.

of electronic chemicals DMF is also widely used in electronic chemicals, such as cleaning agents, etching agents, etc. Because of its strong polarity, it can remove grease and dirt on the surface, so it is used to clean electronic components and printed circuit boards.

In conclusion, N,N-dimethylformamide (DMF) is an important raw material for chemical production and has a wide range of uses. Because of its unique properties and uses, DMF has been widely used in various fields.
