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 sirivha sulfate, amproof, uye multi-oxides muchiyero, wobva wawedzera 1 nguva yakawanda yemvura yakasvibiswa, gadzirisa pH. kukosha kwe sulfuric acid uye ammonia mvura kusvika 6.5 kusvika 7, uye wobva wawedzera sodium silicine uye sodium siliconate uye maererano nechiyero.Mazimbe machena akasviba, anopisa uye anomutswa kuti aite yunifomu mhinduro;fambisa mumvura yekugeza uye condense mhinduro kuti iome, yakaoma pa 100-120 ° C ye6 kusvika 8h, uye wozobika kwe3 kusvika ku5h pa400 ~ 450 ° C. 2. Kugadzirira kweN-hydroxythylpylpyline (NHP) 1) Sanganisa γ-butanol, imwe ethanol, uye ammonia pachiyero che 1.2: 1: 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;Gadzira iyo gasi yakasvibirira musanganiswa pasi pemamiriro eiyo yakagadziriswa mubhedha reactor ye dehydrated catalyst patembiricha ye350 ° C, kudzvanywa kwe0.01MPa uye gasi kumhanya kwe50-300H-1, uye kupera simba kwekushaya mvura mumuviri mune yakatarwa. mubhedha reactor The catalyst inopisa kusvika 390 ° C. Mushure mokunge kupera kwemvura kunosvika pachiyero, N-ethylene cephalopicone (NVP) chigadzirwa chinobudiswa kubva pamubhedha wakagadziriswa.Magasi ealkaline angangoita imwe yeammonia, methylemine, dihamine, trothalmine, uye ethimine.Adopt gas chromatography analysis method, yakabva pa γ-butthite seyero yemukati, ethanol sezvinonyungudutsa, yakaongorora N-ethylene cheedone chigadzirwa chakagadzirwa nenzira iyi, yakaverenga NHP yekushandura chiyero, NVP selectivity, NVP mari, iyo gasi chikamu chechikamu. chikamu chechikamu, icho gasi chikamu chikamu chechikamu chikamu, icho gasi chikamu chechikamu chaive Chromatographic bvunzo mamiriro: TCD detector, Stainless simbi column, poly acetic glycol tannite dilate kugadzirisa mhinduro, nitrogen inoremerwa, silicanerization 102 chena musiyano, gasification mukamuri tembiricha 280 ° C, TCD detector tembiricha 165 ° C, mbiru, makoramu, makoramu Tembiricha ye190 ° C;yakaverengerwa nekuongororwa kwegasi chromatography: NHP kutendeuka mwero we92.8%, NVP selectivity 91.5 %, uye NVP mari ye85.6%.
