What is 2-Pyrrolidinone CAS 616-45-5?

2-Pyrrolidinone is a nitrogen-containing heterocyclic compound and a cyclic amide of gamma aminobutyric acid (GABA). It can be understood as consisting of a five membered ring (4 carbon atoms and 1 nitrogen atom) and a carbonyl group (C=O). 2-Pyrrolidinone is a polar aprotic solvent with high boiling point, low freezing point, strong solubility, excellent thermal and chemical stability.

Application

1. In the polymer industry, the raw material for N-vinylpyrrolidone (NVP), over 80% of 2-pyrrolidone is used to produce NVP, which is then polymerized into polyvinylpyrrolidone (PVP) and polyvinylpyrrolidone (PVPP). These polymers are widely used in fields such as medicine, food, cosmetics, etc.

2. In the electronics industry, photoresist stripping solution: 2-Pyrrolidinone is a key component used in the manufacturing process of semiconductors and display panels to efficiently and safely remove photoresist, which is crucial for the modern electronics industry. Used to improve battery performance and enhance safety.

3. Industrial cleaning and paint stripping agents, with their strong solubility, are used to prepare advanced industrial cleaning agents, especially for removing stubborn resins, inks, coatings, etc.
4. Ink and coatings, as advanced solvents, are used for special inks (such as inkjet ink) and coatings, providing good leveling and stability.

Features

1. Solubility: 2-Pyrrolidinone is miscible with most organic solvents such as water, alcohols, ethers, esters, chlorinated hydrocarbons, and aromatic hydrocarbons, and is a "universal" solvent.

2. Physical constants: High boiling point (245 ° C), low freezing point (-23 ° C), high flash point (129 ° C), good thermal stability.

3. Chemical properties: The chemical properties are active, and its N-H and C=O bonds can participate in various reactions (such as synthesizing NVP).

4. Extremely strong solubility: Capable of dissolving various polymers, resins, dyes, and inorganic salts, with a wide range of applications.
