Habka diyaarinta ee N-ethylene pheasone, oo ay ku jiraan tallaabooyinka soo socda: 1. Kaaliyeyaasha fuuq-baxa ee diyaarinta kaaliyeyaasha fuuq-baxa waxay ka kooban yihiin sulfate qalin, sodium aluminium silicate, dhuxul cad oo madow, amproof, iyo multi-oxide. Saamiga waa: 0.5: 5: 3: 5: 10; Kuwaas ka mid ah, multi-oxides waa shan isku-darka shan oxidation laba -钒 iyo oxide, tin oxide, sex oxide, iyo manganese dioxide; Waa isku-darka shan oxidation dioxide iyo oxide, shan oxidation laba -钒 iyo tin oxide, shan oxidation laba -钒 iyo manganese oxide iyo manganese dioxide. Isku darka toddobaad ee oksaydhka dioxide waa 0.2: 1: 2: 1. Tallaabooyinka wax-soo-saarka ee kaaliyeyaasha fuuq-baxa waa: isku qas sulfate qalin, amproof, iyo multi-oxides saamiga, ka dibna ku dar 1 jeer mugga biyaha la dhalaaliyay, hagaaji qiimaha pH ee sulfuric acid iyo biyaha ammonia 6.5 ilaa 7, ka dibna ku dar sodium silicine iyo sodium siliconate iyo saamiga saamiga. Dhuxusha cad waa madow, waa la kululeeyay oo la walaaqay si loo sameeyo xalka isku midka ah; ku walaaq qubeyska biyaha oo ku qabooji xalka si uu u qalalo, u qallalo 100-120 ° C muddo 6 ilaa 8 saacadood ah, ka dibna dub 3 ilaa 5 saacadood heerkul ah 400 ~ 450 ° C. 2. Diyaarinta N-hydroxyethylpylpyline (NHP) 1) Isku qas γ-butanol, hal ethanol, iyo ammonia saamiga 1.2: 1: 0.2, waxayna ka falcelisaa 0.5MPa iyo 40 ° C. , Samee dhexdhexaad; 2) Ku dar shaandhada molecular ee 0.1WT % iyo 0.1WT % ee dilateyl dihal ether si loo kordhiyo heerkulka ilaa 180 ° C si looga dhigo mid fuuq-baxa 12 saacadood xaalad la hayo; maxaa lagu tilmaamay sida lagu sharraxay; maxaa lagu sheegay? shaandhada molecular waa shaandhada molecular ee 10x chemicalbook ama shaandhada molecular ee 13X. Habkan waxaa loo xushay 10x shaandho molecular ah; 3) kala-saarista cadaadiska, faakuumka waa 0.095MPa, wuxuuna ururiyaa kala-saarista barta karkaraya ee 210 ilaa 216 ° C. Pyrodorrone; 3. Falcelinta fuuq-baxa ee N-hydroxyetylpinol si loo sameeyo dhibcaha kala-saarista ee laga helay diyaarinta N-hydroxyethylpinols oo loo beddelo uumi, oo lagu qaso gaaska alkaline, gaasaska acetylene, iyo nitrogen si loo helo isku-darka walxaha cayriin ee gaaska. Saamiga isku-dhafka ah waa 1: 0.5: 0.1: 0.1; Isku darka walxaha cayriin ee gaaska ah ka dhig mid ku jira xaalad fal-galiye sariir go'an oo ka mid ah fal-galiyaha fuuq-baxa heerkul ah 350 ° C, cadaadiska 0.01 MPa iyo xawaaraha gaaska ee 50-300H-1, iyo fuuq-baxa fuuq-baxa ee fal-galiyaha sariirta go'an Kaaliyeyaasha waxaa lagu kululeeyaa 390 ° C. Ka dib marka fal-galka fuuq-baxa uu gaaro dheelitirka, badeecada N-ethylene cephalopicone (NVP) waxaa laga saaraa fal-galiye sariir go'an. Gaasaska alkaline-ka ah waa ugu yaraan mid ka mid ah ammonia, methylemine, dihamine, trothalmine, iyo ethimine. Qaado habka falanqaynta koromografiga gaaska, iyadoo lagu saleynayo γ-buthite heerka gudaha, ethanol-na sida dareerayaasha, ayaa falanqeeyay badeecada cheedone ee N-ethylene ee lagu diyaariyey habkan, waxay xisaabisay heerka beddelka NHP, xulashada NVP, dakhliga NVP, kaas oo ka mid ah wejiga wejiga wejiga gaaska, kaas oo ka mid ah wejiga wejiga wejiga wejiga, kaas oo ka mid ah wejiga wejiga gaaska uu ahaa xaaladaha tijaabada Chromatographic: TCD detector, tiir bir ah oo aan miridh lahayn, poly acetic glycol tannite dilate fixing solution, nitrogen ayaa la rarayaa, silicanerization 102 isbarbardhig cad, heerkulka qolka gaaska 280 ° C, heerkulka ogaanshaha TCD 165 ° C, tiirar, tiirar, tiirar Heerkulka 190 ° C; lagu xisaabiyay falanqaynta koromografiga gaaska: Heerka beddelka NHP ee 92.8%, xulashada NVP 91.5%, iyo dakhliga NVP ee 85.6%.
