Tallaabooyinka wax soo saarka ee fuuq-baxa daadadku waa: isku darka sulfate lacageed, iyo amberof-ka, ka dibna ku dar 1 jeer mugga biyaha qalafsan, la hagaaji pH Qiimaha aashitada sulfuric iyo biyaha amnia ilaa 6.5 illaa 7, ka dibna ku dar sodium silikine iyo sodium siliconate iyo gudaha u dhiganta cabirka. Dhuxusha Caddaydu waa madow, kuleyl oo lagu kululeeyo si loo sameeyo xalka labiska; Ku walaaq qubeyska biyaha oo ku kari xalka si loo qalajiyo, 100-120 ° C 6 illaa 8h, 40 ~ 40 ~ 45 ~ 45 ~ 45 ~ 45 ~ 45 ~ 45 ~ Isku qas γ-Butanol, hal Ethanol, iyo ammonia saamiga 1.2: 1: 0.2, oo ka falceliya 0.5MPA iyo 40 ° C., samee mid dhexe; 2) Ku dar xingaca-ka-baxa ee molikaga ah 0.1WT% iyo 0.1T% ee Dihal Chihal Ether Ether si aad u kordhiso heerkulka ilaa 180 ° C si aad uga dhigto 12h ee dowlad haynta ah; waxa lagu tilmaamay sida lagu sharaxay; Maxaa lagu xusay? Soconge-ga molialaalka waa 10xchemicalbook BOLOLEPES SI AYULESIVER SITEST. Qaabkan waxaa loo xushay sidii 10x suulyo molikalaal; 3) Murugo Depromprusition, faaruqaha waa 0.095mpa, waxayna aruurisaa muddadii muranka karkaraya barta karkaraya ee 210 ilaa 216 ° C. Pyrododone; 3. Falcelinta fuuq-baxa ee n-hydroxyetylpinol si loo helo dhibcaha musiibada si loo helo diyaarinta n-hydroxyetholpinolpinols, oo lagu qaso gaaska alkaline, iyo gaaska acetylene, iyo nitrogenenes si ay u helaan isku-darka shey cayriin. Saamiga isku dhafka ah waa 1: 0.5: 0.1: 0.1; Ka dhig cufnaanta ceyriinka ah ee loo yaqaan 'paseraus crot' hoostiisa xaalada sariirta jiifka ah ee ka-hortagga kaadi-baxa ee heerkulka 350 ° C, cadaadiska gaaska iyo xawaaraha gaaska ee 50-300h-1, iyo fuuq-baxa fuuq-baxa ee go'an Ka-hortagga sariirta ayaa lagu kululeeyaa 390 ° C. ka dib falcelinta fuuq-baxa ka dib dheelitirka, n-etylnene Shayga Ceephalopico (NVP) ayaa laga soo saaray sariir go'an oo lagu rakibo. Gaasaska alkaline-ka waa ugu yaraan mid ka mid ah ammonia, methylia, Dimaarine, trothaline, iyo ansixine. Qaadashada Habka Falanqaynta Gas-ga, oo ku saleysan γ-laakiin heerka caadiga ah, ethanol madaama ay falanqeeyeen sheyga N-EthereneSelene ee ay diyaarisay qaabkan, oo loo xisaabiyo heerka is-beddelka ee NHP, dakhliga NVP, ee wejiga gaaska. wajiga wejiga, oo ah wajiga wejiga ee wejiga gaaska gaaska ee wajiga wejiga, oo wajiga gaaska gaaska uu ahaa xaaladaha imtixaanka chromasoosic-ka: TCD preactor, tiirar bir ah oo bir ah, polyce acetic glycol tlycol tynite-ka sanka, isbarbardhiga cad, silicament contch heerkulka 160 ° C, tiirarka, tiirarka heerkulka 190 ° C; Waxaa lagu xisaabiyaa falanqaynta koromanka gaaska: Heerka is-beddelka ee NHP ee 92.8%, NVP xulashada NHP 91.5%, iyo dakhliga NVP ee 85.6%.
