Qhov kev faib ua feem yog: 0.5: 5: 3: 5: 10; Ntawm lawv, ntau -OXIDES yog tsib qhov sib tov ntawm tsib oxidation ob - 钒 thiab oxide, tin oxide, sin oxide, pw ua ke, thiab manganese dioxide; Nws yog kev sib xyaw ntawm tsib oxidation dioxide thiab oxide, tsib oxidation ob - 钒 thiab tin thiab tin thiab manganese oxide thiab manganese dioxide. Qhov sib xyaw ntawm xya oxidation dioxide yog 0.2: 2: 1: 1: 1 tus nqi ntawm sulfuric acid thiab ammonia dej rau 6.5 txog 7, thiab tom qab ntawd ntxiv sodium silicine thiab sodium siliconate thiab hauv kev faib ua feem proportions. Dawb lub hluav ncaig yog xim dub, rhuab thiab ua kom muaj kev daws teeb meem; Do hauv cov dej da dej thiab ua kom haum rau ziab qhuav, qhuav ntawm 100-120 ° C rau 6 txog 400 ~ 250 ° ntawm n-hydroxyethylpylpyline (NHP) 1) Sib tov γ-butanol, ib lub ethand, thiab ammonia ntawm ib feem ntawm 1.2: 1: 0.2, thiab reawcts ntawm 0.5Mpa thiab 40 ° C., ua ib Nruab Nrab; 2) ntxiv cov molecular sab cib ntawm 0.1wt% thiab 0.1wt% ntawm dilatehle ether ° C los ua kom nws qhuav dej los ntawm 12h hauv lub xeev khaws cia; Dab tsi yog piav raws li tau piav tseg; Dab tsi yog hais? Cov molecular sab cib yog 10xchemicalBook molecular sab cib lossis 13 x molecular sab cib. Txoj kev no yog xaiv raws li 10 x molecular sieves; 3) Cov decompression distillation, lub tshuab nqus tsev yog 0.095Mpa, thiab sau cov distillation ntawm lub boiling taw tes ntawm 210 txog 21 xyoos ° C. Pyrodororrone; 3. Lub cev tiv thaiv dej hiav txwv ntawm n-hydroxyetylpinol kom cov qhab nia distillation nyob rau hauv cov roj, sib xyaw nrog cov roj av alkalylees, thiab nitrogen kom tau txais cov khoom siv goveous sib xyaw. Cov sib xyaw sib xyaw yog 1: 0.5: 0.1: 0.1; Ua cov khoom siv gaseous sib tov sib xyaw nyob rau hauv cov xwm txheej ntawm ib qho kev kub siab ntawm lub cev qhuav ntawm 0.00H-1, thiab lub cev qhuav dej ntawm lub cev qhuav dej hauv qhov chaw ruaj Lub txaj reactor cov catalyst yog rhuab rau 390 ° C. Tom qab lub cev qhuav dej txog qhov sib npaug, N-ETHYLENE CEPTOPICONE (NVP) cov khoom raug tso tawm los ntawm ib reac tsau. Lub roj alkaline tsawg kawg yog ib qho ntawm ammonia, methylemine, dihhamine, trothalmine, thiab ua kom ncaj. Txais cov roj chromatography, raws li γ-setancholed tus qauv sab hauv, suav nrog cov tshuaj sab hauv cov khoom, suav cov txiaj ntsig kev hloov kho tshiab, suav cov nyiaj tau los ntawm NHP, ntawm cov nyiaj tau los ntawm theem Theem theem, ntawm cov theem theem theem theem theem theem ntu, ntawm cov theem twg theem theem yog cov mob chromatographic: TCD Ntes, stainless hlau kem, poly acetic glycase dilate dilate dures, silmification 102 ° C, txhua yam kub ntawm 190 ° C; xam los ntawm kev tsom xam ntawm cov roj chromatography: NHP hloov dua siab tshiab ntawm 92.8%, NVP Revenity 91.5%, thiab NVP cov nyiaj tau los ntawm 85.6%.
