NVP e sebediswa haholoholo ho hlahisa polyvinylpyrrolidone, e sebediswang haholo mafapheng a meriana, dikhemikhale tsa letsatsi le letsatsi le indasteri ya dijo.

1. E sebelisoa haholo ho litlolo, li-detergents, meriana, thepa ea ho nka lifoto le likarolo tse ling.

2. Bakeng sa li-gel tsa setaele sa moriri, li-disinfectants tsa pharmacy, joalo-joalo.

Mokhoa oa ho lokisetsa N-ethylene pheasone, ho kenyelletsa le mehato e latelang: 1. Li-catalyst tse senyehileng tsa ho lokisoa ha catalyst e senyehileng li na le silevera ea sulfate, sodium aluminium silicate, mashala a masoeu a macha, amproof, le multi-oxide. Karolelano ke: 0.5 : 5: 3: 5: 10; Har'a tsona, li-multi -oxides ke metsoako e mehlano ea oxidation e 'meli -钒 le oxide, tin oxide, sex oxide, le manganese dioxide; Ke motsoako oa oxidation dioxide e mehlano le oxide, tse hlano oxidation tse peli -钒 le tin oxide, tse hlano oxidation tse peli -钒 le manganese oxide le manganese dioxide. Motsoako oa bosupa oa oxidation dioxide ke 0.2: 1: 2: 1. Mehato ea tlhahiso ea li-catalyst tse senyehileng ke: kopanya silevera sulfate, amproof, le multi-oxides ka tekanyo, ebe u eketsa makhetlo a 1 molumo oa metsi a silafetseng, fetola pH ea pH ea sulfuric acid le metsi a ammonia ho 6.5 ebe o eketsa silicon le silicon ea 7, le sodium le silicon e 7, 7 le silicon. tekanyo. Mashala a masoeu a ntšo, a futhumetse ebile a tsosoa ho etsa tharollo e ts'oanang; hlohlelletsa ka ho hlapa metsi le condense tharollo ho omella, ho omella ka 100-120 ° C bakeng sa 6 ho 8h, 'me joale bake bakeng sa 3 ho 5h ka 400 ~ 450 ° C. 2. Ho lokisetsa N-hydroxyethylpylpyline (NHP) 1) Kopanya γ-butanol le 1 ea ammonianol, ethanol e le 'ngoe: ammonianol e le 1. 0.2, mme e arabela ho 0.5MPa le 40 ° C. , Etsa sebaka sa mahareng; 2) Eketsa sieve ea molek'hule ea 0.1WT% le 0.1WT % ea dilateyl dihal ether ho eketsa mocheso ho 180 ° C ho etsa hore e felisoe ke metsi ka 12h sebakeng se bolokiloeng; se hlalosoang se hlalosoa; ho boleloa eng? Sieve ea molek'hule ke 10xchemicalbook molecular sieve kapa 13X molecular sieve. Mokhoa ona o khethoa e le li-sieve tsa 10x tsa molek'hule; 3) decompression distillation, vacuum ke 0.095MPa, 'me e bokella distillation ea ntlha e belang ea 210 ho 216 ° C. Pyrodorrone; 3. The dehydration reaction of N-hydroxyetylpinol ho etsa distillation score fumanwa ho lokisetsa N-hydroxyethylpinols ka mouoane, e tsoakiloeng le alkaline khase, acetylene likhase, le naetrojene ho fumana gaseous thepa e tala motsoako. Karolelano e tsoakiloeng ke 1: 0.5: 0.1: 0.1; Etsa motsoako oa lintho tse tala tse nang le khase tlas'a boemo ba bethe e tsitsitseng ea bethe ea catalyst e senyehileng ka mocheso oa 350 ° C, khatello ea 0.01MPa le lebelo la khase ea 50-300H-1, le ho felloa ke metsi 'meleng ka bethe e tsitsitseng ea bethe The catalyst e futhumala ho 390 dehydration, ° C ka mor'a hore ho fokotsehe metsi ho fihlela ho 390 ° C. Sehlahisoa sa cephalopicone (NVP) se tsoa setsing sa bethe se tsitsitseng. Likhase tsa alkaline bonyane ke e 'ngoe ea ammonia, methylemine, dihamine, trothalmine le ethimine. Adopt gas chromatography analysis method, e thehiloeng ho γ-butthite e le mokhoa oa ka hare, ethanol e le li-solvents, o ile a hlahloba sehlahisoa sa N-ethylene cheedone se lokiselitsoeng ke mokhoa ona, ho baloa sekhahla sa phetoho ea NHP, khetho ea NVP, chelete ea NVP, eo karolo ea khase ea khase ea khase, eo boemo ba khase ea khase e se nang letho e neng e le teng: tšepe kholomo, poly acetic glycol tannite dilate fixing tharollo, naetrojene e laeloa, silicanerization 102 tšoeu phapang, gasification kamoreng mocheso 280 ° C, TCD detector mocheso 165 ° C, litšiea, litšiea, litšiea Mocheso oa 190 ° C; e baloang ka tlhahlobo ea chromatography ea khase: Sekhahla sa phetoho ea NHP ea 92.8 %, khetho ea NVP 91.5 %, le chelete ea NVP ea 85.6%.
