Mugadziri Mutengo Wakanaka N-VINYL PYRROLIDONE (NVP) CAS 88-12-0

NVP inonyanya kushandiswa kugadzira polyvinylpyrrolidone, iyo inoshandiswa zvakanyanya muminda yekurapa, makemikari ezuva nezuva uye indasitiri yechikafu.

1. Inoshandiswa zvakanyanya muzvizoro, sipo, mishonga, zvinhu zvinonzwa chiedza uye zvimwe zvinhu

2. Kune magel ekugadzirisa bvudzi, mishonga yekuuraya utachiona mu pharmacy, nezvimwewo.

Maitiro ekugadzira N-ethylene pheasone, anosanganisira matanho anotevera: 1. Zvishandiso zvekugadzirisa zvicherwa zvine silver sulfate, sodium aluminium silicate, white charcoal black, amproof, uye multi-oxide. Chikamu chacho ndeichi: 0.5 : 5: 3: 5: 10; Pakati pazvo, ma multi-oxides misanganiswa mishanu ye oxidation two -钒 ne oxide, tin oxide, sex oxide, uye manganese dioxide; Musanganiswa we oxidation dioxide mashanu ne oxide, oxidation two -钒 ne tin oxide, oxidation two -钒 ne manganese oxide uye manganese dioxide. Musanganiswa we seventh oxidation dioxide i0.2: 1: 2: 1. Matanho ekugadzira zvicherwa zvine mvura ndeichi: sanganisa silver sulfate, amproof, uye multi-oxides muchiyero, wobva wawedzera ka1 huwandu hwemvura yakasanganiswa, gadzirisa pH ye sulfuric acid nemvura ye ammonia kusvika pa6.5 kusvika pa7, wobva wawedzera sodium silicine ne sodium siliconate uye muchiyero chehuwandu. Marasha machena matema, anopisa uye asanganiswa kuti agadzire mhinduro yakafanana; sanganisa mvura mubhavhu wobva wasanganisa mhinduro kuti iome, oma pa100-120 ° C kwemaawa matanhatu kusvika masere, wobva wabika kwemaawa matatu kusvika mashanu pa400 ~ 450 ° C. 2. Kugadzirira N-hydroxyethylpyline (NHP) 1) Sanganisa γ-butanol, ethanol imwe chete, uye ammonia pachiyero che1.2: 1: 0.2, uye inopindirana pa0.5MPa ne40 ° C. , Gadzira pakati; 2) Wedzera molecular seeve ye0.1WT % uye 0.1WT % ye dilateyl dihal ether kuti uwedzere tembiricha kusvika 180 ° C kuti iome ne12h muchimiro chakachengetedzwa; chii chinotsanangurwa sekutsanangurwa; chii chinotaurwa? Molecular seeve i10xchemicalbook molecular seeve kana 13X molecular seeve. Iyi nzira inosarudzwa se10x molecular seeves; 3) decompression distillation, vacuum cleaner i0.095MPa, uye inounganidza distillation yebolling point ye210 kusvika 216 ° C. Pyrodorrone; 3. Kugadziriswa kwemvura kubva muN-hydroxyetylpinol kuti iite distillation score inowanikwa mukugadzirira N-hydroxyethylpinols musteam, yakasanganiswa nealkaline gas, acetylene gases, uye nitrogen kuti iwane gaseous raw material musanganiswa. Musanganiswa we mixed ratio i1 : 0.5: 0.1: 0.1; Gadzira gaseous raw material muchimiro che fixed bed reactor ye dehydrated catalyst patembiricha ye350 ° C, pressure ye0.01MPa uye gas speed ye50-300H-1, uye dehydration ye dehydration mu fixed bed reactor. Catalyst inopiswa kusvika 390 ° C. Mushure mekunge dehydration reaction yasvika pakuenzana, N-ethylene cephalopicone (NVP) product inoburitswa kubva mu fixed bed reactor. Magasi ealkaline anenge ari eammonia, methylemine, dihamine, trothalmine, uye ethimine. Shandisa nzira yekuongorora gas chromatography, yakavakirwa paγ-butthite seyemukati, ethanol se solvents, yakaongorora chigadzirwa cheN-ethylene cheedone chakagadzirwa nenzira iyi, yakaverenga chiyero chekushandura kweNHP, sarudzo yeNVP, mari yeNVP, iyo gas phase phase phase phase, iyo gas phase phase phase phase, iyo gas phase phase phase phase, iyo gas phase phase phase yaive mamiriro ekuyedza kweChromatographic: 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, makoramu, makoramu, makoramu Tembiricha ye190 ° C; yakaverengerwa nekuongorora gas chromatography: NHP conversion rate ye92.8%, NVP selectivity 91.5%, uye NVP revenue ye85.6%.
