N-Vinyl-2-pyrrolidone (NVP), also known by its CAS number 88-12-0, is a pivotal intermediate chemical with a wide array of applications, most notably as the monomer for polyvinylpyrrolidone (PVP). For chemical engineers, R&D scientists, and procurement managers, a thorough understanding of NVP’s characteristics, production, and sourcing is essential. As a seasoned N-Vinyl-2-pyrrolidone manufacturer, we aim to provide clarity on these critical aspects.

Physically, N-Vinyl-2-pyrrolidone presents as a colorless to pale yellow liquid at room temperature, with a mild odor. It has a melting point around 13-14 °C, meaning it can solidify in cooler conditions. Crucially, NVP is highly miscible with water and a broad spectrum of organic solvents, which enhances its utility in various formulations. Its chemical reactivity, particularly its tendency to polymerize and hydrolyze, necessitates stabilization with inhibitors such as sodium hydroxide or TMHPO for extended storage. Maintaining NVP below 30°C during storage and handling is recommended to prevent degradation and ensure product integrity.

The primary industrial method for NVP production is the reaction of 2-pyrrolidone with acetylene. This vinylation process, typically carried out at elevated temperatures and pressures with a potassium catalyst, yields crude NVP which is then purified through vacuum distillation. The efficiency and purity of this process are paramount, and as a dedicated manufacturer, we meticulously control these parameters. This ensures that the NVP we supply meets industry-specific requirements, whether for general chemical synthesis or specialized pharmaceutical applications.

When seeking to purchase N-Vinyl-2-pyrrolidone, it is vital to evaluate potential suppliers based on their product quality, production capacity, and supply chain reliability. Key specifications to confirm include the assay (typically ≥99.5%), appearance, moisture content, and the type and concentration of stabilizers used.
