Product Description
N-Vinyl-2-pyrrolidone (N-Vinyl-2-pyrrolidone) for short NVP, also known as 1-vinyl-2-pyrrolidone, n-vinyl-2-pyrrolidone. At room temperature, it is a colorless or light yellow transparent liquid with a slight odor, easily soluble in Chemicalbook water and other organic solvents. N-vinylpyrrolidone is widely used because it can increase the physical and chemical properties of products: in radiation medicine, wooden flooring industry, paper or paperboard industry, packaging materials, screen ink industry through the use of NVP to improve the physical properties of products.For hair styling gel, pharmacy disinfectant, etc.
A test method for N-vinylpyrrolidone includes the following steps: 1) sample solution and reference solution to prepare sample solution: weigh the sample in a glass bottle, grind it into powder, add 5 ~ 15 times the weight of the extractant, ultrasonic extraction for 20 ~ 40min, centrifuge separation, take the supernatant and filter it, obtain the filtrate, and reserve; Reference solution: Take N-vinylpyrrolidone reference product, one weight of the same extraction agent as the sample solution, shake well, set aside; 2) Liquid chromatograph conditional column: SFC capillary Chemicalbook column; Stationary phase: octadecylsilane bonded silica gel as the filling column; Column temperature: 36-38ºC, sample volume: 20-30μL; Mobile phase: C2H3N-N2O-CH4O with volume ratio of 5:3:50 is used as mobile phase; Detection wavelength: 200 ~ 215nm; Constant pressure: 65.7×106Pa; The flow rate was 1 ~ 1.5ml/min. Detection point: FID, 250ºC; Replenishing gas: nitrogen; 3) Determination Absorb the reference solution and the sample solution respectively, and inject the liquid chromatograph for determination.
