N-甲氧基-N-甲基丙酰胺 - Introduction

N-Methoxy-N-methyl-propionamide, chemical formula C5H11NO2, often abbreviated as NMP, is a colorless liquid. It has some of the following properties:

1. High solubility: NMP has good solubility in water and can dissolve with many organic solvents.

2. High boiling point and flash point: The boiling point of NMP is 202°C, and the flash point is 85°C, making it usable under high temperature reaction conditions.

3. Stability: NMP is relatively stable under conventional storage conditions and can withstand certain heat and oxidation conditions.

N-Methoxy-N-methyl-propionamide is widely used in different fields:

1. Reaction solvent: NMP is a solvent with low viscosity, high solubility and high boiling point. It is used as a solvent in many organic synthesis reactions.

2. Battery manufacturing: NMP is used as a polymer solvent and medium in battery manufacturing, and is related to lithium ion batteries and polyamide lithium batteries.

3. Printed circuit board manufacturing: NMP is used as a fluoride solvent to remove residues on the surface of the circuit board.

N-methoxy-N-methyl-propionamide can be produced by acylation of propionic acid. First, methanol is reacted with formaldehyde to prepare a methanol acetal. The methanol acetal is then acylated with propionic acid to give N-methoxy-N-methyl-propionamide.

When using N-methoxy-N-methyl-propionamide, you need to pay attention to the following safety information:

1. Irritating to skin and eyes, rinse with plenty of water immediately after contact.

2. Avoid inhaling its vapor, and use ventilation equipment to maintain air circulation.

3. should be stored away from the fire and oxidant, avoid contact with flammable substances.

4. Use should wear appropriate personal protective equipment, such as chemical protective glasses and gloves.

In short, N-methoxy-N-methyl-propionamide is a commonly used solvent that has a wide range of applications in organic synthesis and electronics, and needs to be used under safe operation.
