N, N-dimethyl-2-piperidinecarboxamide (N,N-Dimethyl-2-pyrrolidone, DMF) is an important organic solvent and chemical raw material. The following is a description of the nature, use, preparation and safety information of DMF:

Nature:
1. Appearance: DMF is a colorless to yellowish liquid.
2. Melting point and boiling point: The melting point of DMF is -60°C, and the boiling point is 153°C.
3. density: the density of DMF is 1.03g/cm³.
4. Solubility: DMF is soluble in water, ethanol, ethers, ketones and other solvents.

Use:
1. Solvent: DMF as a solvent has strong solubility, widely used in the synthesis of organic compounds, polymer solutions and dye solutions and other fields.
2. chemical raw materials: DMF is the production of polyamide fiber, polyamide resin, polyimide and fluorescent whitening agent and other important chemical raw materials.
3. pharmaceutical field: DMF can be used as a solvent or extractant in pharmaceutical preparation, and can also be used for the extraction of traditional herbs.

Preparation Method:
DMF is generally prepared by reacting N-methyl pyrrole with methyl methacrylate in the presence of an oxidant.

Safety Information:
1. Chemical properties: DMF is a non-flammable liquid, but it may decompose at high temperatures to produce very toxic nitrogen oxides.
2. toxicity: DMF vapor can be absorbed through the skin and respiratory tract, with certain toxicity. Long-term exposure to high concentrations of DMF can cause damage to the human body, especially to the liver and central nervous system.
3. safety precautions: when using DMF should wear protective gloves, protective goggings and protective mask, avoid contact with skin and inhalation of its vapor. Storage should be kept away from fire sources and open flames, keep the container airtight, and store in a well-ventilated place.

Please note that DMF is a chemical and should be used in accordance with relevant safety regulations to ensure proper handling and storage.
