Nga tono mo te NVP
Ko te NVP te nuinga o te waa ki te whakaputa i te polyvinylpyrrolidone, e whakamahia nuitia ana i roto i nga mara rongoa, matū o ia ra me te ahumahi kai.
1. Ka whakamahia nuitia i roto i nga mea whakapaipai, i nga mea horoi, i nga rongoa, i nga taonga whakaahua me etahi atu mara
2. Mo nga reera whakapaipai makawe, nga rongoa rongoa rongoa, aha atu.
Ko te tukanga whakarite o te N-ethylene pheasone, tae atu ki nga waahanga e whai ake nei: 1. Ko nga whakakorikori whakamaroke o te whakarite o te whakakorikori whakamaroke kei roto te hiriwa sulfate, te konutai konumohe silicate, te waro ma pango, te amproof, me te maha-waikura.Ko te wahanga: 0.5 : 5: 3: 5: 10;I roto i era, ko te maha-waikura e rima nga ranunga o te rima o te waikura rua -钒 me te waikura, te waikura tine, te waikura ira, me te waikura konupora;He ranunga o te waikura e rima me te waikura, e rima te waikura e rua -钒 me te waikura tine, e rima te waikura rua -钒 me te konupora waikura me te konupora waikura.Ko te ranunga o te hauhautanga whakahiato tuawhitu ko te 0.2: 1: 2: 1. Ko nga mahi whakangao o te whakakorikori whakamaroke ko: uruhia te konukawata hiriwa, te amproof, me te maha o te waikura, katahi ka taapirihia kia 1 nga wa te rōrahi o te wai māturu, whakatikahia te pH te uara o te waikawa pungatara me te wai haukini ki te 6.5 ki te 7, katahi ka tapirihia te konutai silicine me te konutai konutai me te rite ki te rahinga.He pango te waro ma, ka wera, ka whakakorikoria kia rite te otinga;whakaohokia i roto i te pati wai me te whakamaroke i te otinga kia maroke, kia maroke i te 100-120 ° C mo te 6 ki te 8h, ka tunu mo te 3 ki te 5h i te 400 ~ 450 ° C. 2. Te Whakaritenga o N-hydroxyethylpylpyline (NHP) 1) Whakaranuhia te γ-butanol, kotahi ewaro, me te haukini i te ōwehenga o te 1.2: 1: 0.2, ka tauhohe ki te 0.5MPa me te 40 ° C. , Hangaia he takawaenga;2) Tāpirihia te tatari rāpoi o te 0.1WT % me te 0.1WT % o te dilateyl dihal ether hei whakanui ake i te pāmahana ki te 180 ° C kia maroke ai i te 12h i roto i te ahua mau;he aha te mea e whakaahuatia ana;he aha te korero?Ko te tatari rāpoi he 10xchemicalbook molecular sieve ranei 13X rapoi tatari.Ko tenei tikanga ka tohua hei tatari mole 10x;3) te whakamarumaru whakaheke, ko te 0.095MPa te korehau, ka kohia te whakamaaramatanga o te ira kohua o 210 ki te 216 ° C. Pyrodorrone;3. Ko te tauhohenga whakamaroketanga o te N-hydroxyetylpinol ki te hanga i te kaute whakamarumaru i roto i te whakarite o nga N-hydroxyethylpinols ki te mamaoa, i konatunatua ki te hau kawakore, nga hau acetylene, me te hauota kia whiwhi ai te ranunga rauemi mata hau.Ko te ōwehenga whakauru he 1 : 0.5: 0.1: 0.1;Hangaia te ranunga rauemi mata hau i raro i te ahua o te reactor moenga o te whakakorikori whakamaroke i te pāmahana o te 350 ° C, te pehanga o te 0.01MPa me te tere hau o 50-300H-1, me te whakamaroketanga o te matewai i roto i te waahi reactor moenga Ka whakawerahia te whakakorikori ki te 390 ° C. I muri i te tauhohenga matewai ka tae ki te pauna, ka tukuna te hua N-ethylene cephalopicone (NVP) mai i te reactor moenga.Ko nga hau kawakore he haukini, te methylemine, te dihamine, te trothalmine, me te ethimine.Whakamahia te tikanga tātari hau chromatography, i runga i te γ-butthite hei paerewa o roto, te waihano hei whakarewa, i tātarihia te hua N-ethylene cheedone i mahia ma tenei tikanga, i tatau i te reeti hurihanga NHP, te whiriwhiringa NVP, nga moni whiwhi NVP, o te wahanga hau. te wahanga o te hau, ko te wahanga o te hau ko nga tikanga whakamatautau Chromatographic: TCD detector, he kowiri tira, poly acetic glycol tannite dilate solution fixing solution, hauota te utaina, silicanerization 102 ma te rereke, hau whakawera 280 ° C, TCD detector pāmahana 165 ° C, tīwae, tīwae, tīwae Te pāmahana o 190 ° C;ka tatauhia e te tātaritanga o te chromatography hau: 92.8% te huringa NHP, 91.5% te whiriwhiringa NVP, me te 85.6% te whiwhinga NVP.
