Applications of NVP

NVP is mainly used to produce polyvinylpyrrolidone, which is widely used in the fields of medicine, daily chemical and food industry.

1. Widely used in cosmetics, detergents, medicine, photosensitive materials and other fields

2. For hair styling gels, pharmacy disinfectants, etc.

The preparation process of N-ethylene pheasone, including the following steps: 1. The dehydrated catalysts of the preparation of dehydrated catalyst contain silver sulfate, sodium aluminum silicate, white charcoal black, amproof, and multi-oxide. The proportion is: 0.5 : 5: 3: 5: 10; Among them, the multi -oxides are five mixtures of five oxidation two -钒 and oxide, tin oxide, sex oxide, and manganese dioxide; It is a mixture of five oxidation dioxide and oxide, five oxidation two -钒 and tin oxide, five oxidation two -钒 and manganese oxide and manganese dioxide. The mixture of the seventh oxidation dioxide is 0.2: 1: 2: 1. The production steps of dehydrated catalysts are: mix silver sulfate, amproof, and multi -oxides in proportion, then add 1 times the volume of distilled water, adjust the pH value of sulfuric acid and ammonia water to 6.5 to 7, and then add sodium silicine and sodium siliconate and in proportion to proportions. White charcoal is black, heated and stirred to make the uniform solution; stir in the water bath and condense the solution to dry, dry at 100-120 ° C for 6 to 8h, and then bake for 3 to 5h at 400 ~ 450 ° C. 2. Preparation of N-hydroxyethylpylpyline (NHP) 1) Mix γ-butanol, one ethanol, and ammonia at a ratio of 1.2: 1: 0.2, and reacts at 0.5MPa and 40 ° C. , Make an intermediate; 2) Add the molecular sieve of 0.1WT % and 0.1WT % of the dilateyl dihal ether to increase the temperature to 180 ° C to make it dehydrated by 12h in a retained state; what is described as described; what is mentioned? The molecular sieve is 10xchemicalbook molecular sieve or 13X molecular sieve. This method is selected as 10x molecular sieves; 3) decompression distillation, the vacuum is 0.095MPa, and collects the distillation of the boiling point of 210 to 216 ° C. Pyrodorrone; 3. The dehydration reaction of N-hydroxyetylpinol to make the distillation score obtained in the preparation of N-hydroxyethylpinols into steam, mixed with alkaline gas, acetylene gases, and nitrogen to obtain gaseous raw material mixture. The mixed ratio is 1 : 0.5: 0.1: 0.1; Make the gaseous raw material mixture under the condition of a fixed bed reactor of the dehydrated catalyst at a temperature of 350 ° C, the pressure of 0.01MPa and the gas speed of 50-300H-1, and the dehydration of dehydration in the fixed bed reactor The catalyst is heated to 390 ° C. After the dehydration reaction reaches the balance, the N-ethylene cephalopicone (NVP) product is discharged from a fixed bed reactor. The alkaline gases are at least one of ammonia, methylemine, dihamine, trothalmine, and ethimine. Adopt gas chromatography analysis method, based on γ-butthite as the internal standard, ethanol as the solvents, analyzed the N-ethylene cheedone product prepared by this method, calculated the NHP conversion rate, NVP selectivity, NVP revenue, of which gas phase phase phase phase, of which gas phase phase phase phase phase, of which gas phase phase was Chromatographic test conditions: TCD detector, stainless steel column, poly acetic glycol tannite dilate fixing solution, nitrogen is loaded, silicanerization 102 white contrast, gasification room temperature 280 ° C, TCD detector temperature 165 ° C, columns, columns, columns The temperature of 190 ° C; calculated by the analysis of the gas chromatography: NHP conversion rate of 92.8 %, NVP selectivity 91.5 %, and NVP revenue of 85.6 %.
