Soo saaraha Qiimaha Wanaagsan N-VINYL PYRROLIDONE (NVP) CAS 88-12-0

NVP waxaa inta badan loo isticmaalaa in lagu soo saaro polyvinylpyrrolidone, kaas oo si weyn loogu isticmaalo dhinacyada daawada, kiimikooyinka maalinlaha ah iyo warshadaha cuntada.

1. Si weyn loogu isticmaalo waxyaabaha la isku qurxiyo, saabuunta, dawooyinka, agabka xasaasiga ah iyo meelaha kale

2. Jeel-ka-habaynta timaha, jeermiska-jeermiska farmashiyaha, iwm.

Habka diyaarinta ee pheasone N-ethylene, oo ay ku jiraan tallaabooyinka soo socda: 1. Ka-hortagga fuuqbaxa ee diyaarinta kicinta fuuqbaxa waxay ka kooban tahay sulfate silver, sodium aluminium silicate, dhuxusha cad madow, amproof, iyo multi-oxide.Saamiga waa: 0.5: 5: 3: 5: 10;iyaga ka mid ah, multi-oxides waa shan isku darka shan oksaydhdhation laba -钒 iyo oxide, tin oxide, sex oxide, iyo manganese dioxide;Waa isku dhafka shan oksaydhation dioxide iyo oxide, shan oksaydhation laba -钒 iyo tin oxide, shan oksaydhation laba -钒 iyo manganese oxide iyo manganese dioxide.Isku dar ah oksaydhation-ka toddobaad waa 0.2: 1: 2: 1. Tallaabooyinka wax soo saarka ee kicinta fuuqbaxa waa: isku darka sulfate silver, amproof, iyo multi-oxides ee saamiga, ka dibna ku dar 1 jeer mugga biyaha nadiifka ah, hagaajin pH Qiimaha sulfuric acid iyo biyaha ammonia ilaa 6.5 ilaa 7, ka dibna ku dar silicine sodium iyo silikoon sodium iyo qiyaasta qiyaasta.Dhuxusha cad waa madow, kuleyl iyo walaaq si ay u sameeyaan xal isku mid ah;ku walaaq biyaha qubeyska oo isku ururi xalka si aad u qallajiso, u qallajiso 100-120 ° C 6 ilaa 8h, ka dibna dubi 3 ilaa 5h at 400 ~ 450 ° C. 2. Diyaarinta N-hydroxyethylpylpyline (NHP) 1) Isku qas γ-butanol, hal ethanol, iyo ammonia oo ah saamiga 1.2: 1: 0.2, oo ka falceliya 0.5MPa iyo 40 ° C., Samee dhexdhexaad ah;2) Ku dar shaandhada molecular ee 0.1WT % iyo 0.1WT % ether dilateyl dihal si aad u kordhiso heerkulka ilaa 180 ° C si ay u fuuq baxdo 12h xaalad la hayo;waxa lagu tilmaamay sida lagu tilmaamay;maxaa lagu sheegay?Shaandho molecular waa 10x shaandho molecular book ama 13X shaandho molecular.Habkan waxaa loo doortay sida 10x shaandho molecular;3) Distillation decompression, faakuumku waa 0.095MPa, oo ururiya distillation barta karkaraya ee 210 ilaa 216 ° C. Pyrodorrone;3. Dareen-celinta fuuq-baxa ee N-hydroxyetylpinol si loo sameeyo dhibcaha distillation ee lagu helay diyaarinta N-hydroxyethylpinols ee uumiga, oo lagu qaso gaaska alkaline, gaaska acetylene, iyo nitrogen si loo helo isku-darka alaabta ceeriin.Saamiga isku dhafan waa 1: 0.5: 0.1: 0.1;Samee isku dar ah walxo cayriin ah oo ku hoos jira xaalad fal-celinta sariirta go'an ee kicinta fuuqbaxa heerkul ah 350 ° C, cadaadiska 0.01MPa iyo xawaaraha gaaska 50-300H-1, iyo fuuqbaxa fuuqbaxa go'an kicinta sariirta Kiciyahu waxa lagu kululeeyaa 390 ° C. Ka dib falcelinta fuuq-baxa ay gaadho dheelitirka, badeecada N-etylene cephalopicone (NVP) ayaa laga soo daayaa reactor go'an.Gaasaska alkalineku waa ugu yaraan mid ka mid ah ammonia, methylemine, dihamine, trothalmine, iyo ethimine.Qaado habka falanqaynta chromatography gaaska, oo ku salaysan γ-butthite oo ah heerka gudaha, ethanol oo ah dareerayaasha, ayaa falanqeeyay sheyga N-etylene Cheedone ee lagu diyaariyay habkan, xisaabiyay heerka beddelka NHP, xulashada NVP, dakhliga NVP, kaas oo wajiga wajiga gaaska wejiga wejiga, kaas oo wejiga wejiga wejiga gaaska wejiga wejiga, kaas oo weji gaas wejiga wejiga wejiga, kaas oo wejiga wejiga gaaska ahaa xaaladaha tijaabada Chromatographic: Baaraha TCD, tiirarka ahama, poly acetic glycol tannite dilate xalinta xalinta, nitrogen waa raran, silicanerization 102 cad cad, heerkulka qolka gasification 280 ° C, heerkulka baaraha TCD 165 ° C, tiirarka, tiirarka, tiirarka Heerkulka 190 ° C;lagu xisaabiyey falanqaynta chromatography gaaska: heerka beddelka NHP ee 92.8 %, NVP xulashada 91.5 %, iyo dakhliga NVP 85.6 %.
