1. Dav siv nyob rau hauv tshuaj pleev ib ce, detergents, tshuaj, photosensitive ntaub ntawv thiab lwm yam teb

2. Rau cov plaub hau styling gels, tshuaj tua kab mob, thiab lwm yam.

Cov txheej txheem kev npaj ntawm N-ethylene pheasone, suav nrog cov kauj ruam hauv qab no: 1. Lub cev qhuav dej catalysts ntawm kev npaj cov dej dehydrated catalyst muaj nyiaj sulfate, sodium aluminium silicate, dawb charcoal dub, amproof, thiab multi-oxide.Qhov kev faib ua feem yog: 0.5: 5: 3: 5: 10;Ntawm lawv, cov multi-oxides yog tsib sib tov ntawm tsib oxidation ob - 钒 thiab oxide, tin oxide, txiv neej oxide, thiab manganese dioxide;Nws yog qhov sib xyaw ntawm tsib oxidation dioxide thiab oxide, tsib oxidation ob - 钒 thiab tin oxide, tsib oxidation ob - 钒 thiab manganese oxide thiab manganese dioxide.Qhov sib tov ntawm xya oxidation dioxide yog 0.2: 1: 2: 1. Cov kauj ruam ntawm cov dej dehydrated catalysts yog: sib tov nyiaj sulfate, amproof, thiab multi-oxides hauv kev faib ua feem, ces ntxiv 1 npaug ntawm cov dej distilled, kho cov pH. tus nqi ntawm sulfuric acid thiab ammonia dej mus rau 6.5 mus rau 7, thiab ces ntxiv sodium silicine thiab sodium siliconate thiab nyob rau hauv proportions rau proportions.Dawb charcoal yog xim dub, rhuab thiab nplawm kom ua cov tshuaj sib xws;do hauv cov dej da dej thiab condense cov tshuaj kom qhuav, qhuav ntawm 100-120 ° C rau 6 mus rau 8h, thiab tom qab ntawd ci rau 3 mus rau 5h ntawm 400 ~ 450 ° C. 2. Kev npaj N-hydroxyethylpylpyline (NHP) 1) Sib tov γ-butanol, ib qho ethanol, thiab ammonia ntawm qhov sib piv ntawm 1.2: 1: 0.2, thiab reacts ntawm 0.5MPa thiab 40 ° C., Ua ib qho nruab nrab;2) Ntxiv cov molecular sieve ntawm 0.1WT % thiab 0.1WT % ntawm dilateyl dihal ether kom qhov kub thiab txias mus rau 180 ° C kom nws lub cev qhuav dej los ntawm 12h nyob rau hauv lub xeev khaws cia;dab tsi yog piav raws li piav;hais dab tsi?Molecular sieve yog 10xchemicalbook molecular sieve los yog 13X molecular sieve.Txoj kev no yog xaiv raws li 10x molecular sieves;3) decompression distillation, lub tshuab nqus tsev yog 0.095MPa, thiab sau cov distillation ntawm boiling point ntawm 210 mus rau 216 ° C. Pyrodorrone;3. Cov tshuaj tiv thaiv lub cev qhuav dej ntawm N-hydroxyetylpinol los ua kom cov qhab nia distillation tau txais hauv kev npaj N-hydroxyethylpinols rau hauv chav, sib xyaw nrog cov roj alkaline, acetylene gases, thiab nitrogen kom tau cov khoom siv raw khoom sib xyaw.Qhov sib xyaw ua ke yog 1: 0.5: 0.1: 0.1;Ua kom cov khoom siv roj gaseous sib tov nyob rau hauv cov xwm txheej ntawm lub txaj ruaj khov reactor ntawm lub cev qhuav dej catalyst ntawm qhov kub ntawm 350 ° C, lub siab ntawm 0.01MPa thiab roj ceev ntawm 50-300H-1, thiab lub cev qhuav dej ntawm lub cev qhuav dej hauv qhov ruaj khov. txaj reactor Lub catalyst yog rhuab mus rau 390 ° C. Tom qab lub cev qhuav dej cov tshuaj tiv thaiv mus txog qhov sib npaug, cov khoom N-ethylene cephalopicone (NVP) raug tso tawm los ntawm lub txaj ruaj khov reactor.Cov roj alkaline tsawg kawg yog ib qho ntawm ammonia, methylamine, dihamine, trothalmine, thiab ethimine.Txais cov roj chromatography tsom xam txoj kev, raws li γ-butthite raws li tus qauv sab hauv, ethanol ua cov kuab tshuaj, tshuaj xyuas cov khoom N-ethylene cheedone npaj los ntawm txoj kev no, suav cov NHP hloov pauv tus nqi, NVP xaiv, NVP cov nyiaj tau los, ntawm theem roj theem. theem theem, ntawm cov roj theem theem theem theem, uas theem roj theem yog Chromatographic kuaj tej yam kev mob: TCD detector, stainless steel kem, poly acetic glycol tannite dilate fixing tov, nitrogen yog loaded, silicanerization 102 dawb sib piv, gasification chav tsev kub 280 ° C, TCD detector kub 165 ° C, kab, kab, txhua kab Qhov kub ntawm 190 ° C;xam los ntawm kev txheeb xyuas cov roj chromatography: NHP hloov pauv tus nqi ntawm 92.8%, NVP xaiv 91.5%, thiab NVP cov nyiaj tau los ntawm 85.6%.
