N-Vinylpyrrolidone (NVP) is an organic compound consisting of a 5-membered lactam ring linked to a (2 carbon) vinyl group. It is a colorless liquid although commercial samples can appear yellowish. It is produced industrially by vinylation of 2-pyrrolidone, i.e. the base-catalyzed reaction with acetylene. [2]
A release agent (also mold release agent, release coating, or mold release coating) is a chemical used to prevent other materials from bonding to surfaces. Release agents aid in processes involving mold release, die-cast release, plastic release, adhesive release, and tire and web release. [1] Release agents are one of many additives used in ...
as a binder and complexation agent in agricultural applications such as crop protection, seed treatment and coating as a thickening agent in tooth whitening gels [ 15 ] as an aid for increasing the solubility of drugs in liquid and semi-liquid dosage forms ( syrups , soft gelatine capsules ) and as an inhibitor of recrystallisation [ 16 ]
2-Pyrrolidone, also known as 2-pyrrolidinone or butyrolactam, is an organic compound consisting of a 5-membered lactam, making it the simplest γ-lactam. It is a colorless liquid that is miscible with water and most common organic solvents.
Using the same principle it is used to remove polyphenols in beer production and thus clear beers with stable foam are produced. [2] One such commercial product is called Polyclar. PVPP forms bonds similar to peptidic bonds in protein (especially, like proline residues) and that is why it can precipitate tannins the same way as proteins do.
4-686-293-01, also known as Agent 1-10, is a highly potent experimental carbamate nerve agent, patented in May 1967 by the US army. [1] Due to its high molecular weight and thermal stability, it can remain embedded within various surfaces and clothes for prolonged periods of time. The agent can be decontaminated using bleach or hot caustic soda.
N-Methyl-2-pyrrolidone (NMP) is classified as a reproductive toxicant (H360D: May damage the unborn child) and can cause skin and eye irritation and respiratory irritation (H315, H319, H335). [8] Studies show NMP exposure can increase the risk of developmental toxicity, including miscarriage and fetal death.
In the United States military, the Mark I NAAK, or MARK I Kit, ("Nerve Agent Antidote Kit") is a dual-chamber autoinjector: Two anti-nerve agent drugs—atropine sulfate and pralidoxime chloride—each in injectable form, constitute the kit. The kits are only effective against the nerve agents tabun (GA), sarin (GB), soman (GD) and VX.
