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

NVP inonyanya kushandiswa kugadzira polyvinylpyrrolidone, iyo inoshandiswa zvakanyanya muminda yemishonga, makemikari emazuva ese uye indasitiri yechikafu.

1. Inoshandiswa zvakanyanya muzvizoro, detergents, mushonga, photosensitive zvinhu nezvimwe minda.

2. Zvekugadzira bvudzi gels, pharmacy disinfectants, nezvimwe.

Nzira yekugadzirira yeN-ethylene pheasone, kusanganisira matanho anotevera: 1. Zvikonzero zvakasvibiswa zvekugadzirira kwemvura yakasvibiswa ine silver sulfate, sodium aluminium silicate, white charcoal black, amproof, uye multi-oxide. Chikamu ndeichi: 0.5 : 5: 3: 5: 10; Pakati pavo, iyo yakawanda-okisijeni misanganiswa mishanu yeshanu oxidation maviri -钒 uye oxide, tin oxide, sex oxide, uye manganese dioxide; Musanganiswa weshanu oxidation dioxide uye oxide, mashanu oxidation maviri -钒 uye tin oxide, mashanu oxidation maviri -钒 uye manganese oxide uye manganese dioxide. Iko kusanganiswa kwechinomwe oxidation dioxide ndeye 0.2: 1: 2: 1. Matanho ekugadzirwa kwezvinokonzera zvakasvibiswa ndezvi: sanganisa sirivheri sulfate, amproof, uye multi-oxides muhuwandu, wobva wawedzera 1 nguva yakawanda yemvura yakasvibiswa, gadzirisa pH kukosha kwe sulfuric acid uye ammonia mvura kusvika 6.5 wobva wawedzera silicon ku 7, silicon oxide uye silicon 7. zviyero. Mazimbe machena akasviba, anopisa uye anomutswa kuti aite yunifomu mhinduro; simbisa mumvura yekugezera uye condense mhinduro yekuoma, yakaoma pa 100-120 ° C ye6 kusvika 8h, uye wozobika kwe3 kusvika ku5h pa400 ~ 450 ° C. 2. Kugadzirira kweN-hydroxyethylpylpyline (NHP) 1) Sanganisa γ-butanol uye 1 chiyero cheammonianol: 1 ethanol, 1 ethanol. 0.2, uye inopindura pa 0.5MPa uye 40 ° C. , Ita yepakati; 2) Wedzera iyo molecular sieve ye 0.1WT % uye 0.1WT % ye dilateyl dihal ether kuwedzera tembiricha kusvika 180 ° C kuti iite kupera mvura ne12h mune yakachengetwa mamiriro; izvo zvinorondedzerwa sezvinotsanangurwa; chii chataurwa? Iyo molecular sieve ndeye 10xchemicalbook molecular sieve kana 13X molecular sieve. Iyi nzira inosarudzwa se 10x molecular sieves; 3) decompression distillation, vacuum iri 0.095MPa, uye inounganidza distillation yenzvimbo yekubikira ye210 kusvika 216 ° C. Pyrodorrone; 3. The dehydration reaction yeN-hydroxyetylpinol kuti iite distillation score inowanikwa mukugadzirira kweN-hydroxyethylpinols mumhepo, yakasanganiswa nealkaline gas, acetylene magasi, uye nitrogen kuwana gaseous raw material musanganiswa. Iyo yakasanganiswa chiyero ndeye 1: 0.5: 0.1: 0.1; Ita gaseous raw material musanganiswa pasi pemamiriro emubhedha wakagadziriswa reactor we dehydrated catalyst pa tembiricha ye 350 ° C, kumanikidzwa kwe 0.01MPa uye gasi kumhanya kwe50-300H-1, uye kupera kwemvura mumubhedha wakagadziriswa reactor The catalyst inopisa kusvika 390 dehydration, ° C inosvika 390 dehydration. cephalopicone (NVP) chigadzirwa chinobudiswa kubva pamubhedha wakagadziriswa reactor. Magasi ealkaline angangoita imwe yeammonia, methylemine, dihamine, trothalmine, uye ethimine. Adopt gasi chromatography yekuongorora nzira, yakavakirwa pa γ-butthite seyemukati chiyero, ethanol sezvinonyungudutsa, yakaongorora N-ethylene cheedone chigadzirwa chakagadzirirwa neiyi nzira, yakaverengera iyo NHP yekushandura chiyero, NVP selectivity, NVP mari, iyo iyo gas phase phase phase phase, iyo iyo gas phase phase phase phase dedetect, which gamatographic phase phase phase dedetect, which gamatographic phase level test, which simbi mbiru, poly acetic glycol tannite dilate kugadzirisa mhinduro, nitrogen inotakurwa, silicanerization 102 chena kusiyana, gasification mukamuri tembiricha 280 ° C, TCD detector tembiricha 165 ° C, mbiru, mbiru, makoramu Kupisa kwe190 ° C; yakaverengerwa nekuongororwa kwegasi chromatography: NHP kutendeuka mwero we92.8%, NVP selectivity 91.5 %, uye NVP mari ye85.6%.
