Vinylpyrrolidone (NVP) is a colorless or light yellow transparent liquid with a slight odor at room temperature. It is easily soluble in water and a variety of organic solvents and is very easy to hydrolyze and polymerize. It is a key monomer for the synthesis of polymers such as polyvinylpyrrolidone (PVP).
Core use: Vinyl pyrrolidone is a key raw material for the synthesis of polyvinyl pyrrolidone, which is widely used in many industries.
Multiple applications: Used in medicine to prepare drug adhesives and coating materials; in the cosmetics field as a raw material for hair spray, mousse and some skin care products; in industry, it can be used for acetylene and butadiene extraction, natural gas desulfurization, and can also serve as an insecticide component and pigment dispersant.
Storage points: It needs to be kept airtight, stored in a light-proof, low-temperature environment, and maintained in neutral or weakly alkaline conditions.
FAQ
Q: How to ensure the purity of the product?
A: Using continuous distillation process, the purity is stable at more than 99.5%. Each batch is tested by GC-MS, and the impurity content is less than 0.1%.
Q: How to avoid polymerization risk?
A: Add 0.01-0.05% high-efficiency inhibitor (such as hydroquinone), the polymerization rate during the storage period is less than 0.05%, and provide the type and amount of inhibitor report.
Q: Is there a qualification document for food contact grade?
