Mokhoa oa ho lokisa N-ethylene pheasone, ho kenyeletsoa le mehato e latelang: 1. Li-catalyst tse se nang metsi tsa ho lokisa catalyst e se nang metsi li na le silver sulfate, sodium aluminium silicate, mashala a masoeu a matšo, amproof, le multi-oxide. Karolo ke: 0.5 : 5: 3: 5: 10; Har'a tsona, li-oxide tse ngata ke metsoako e mehlano ea oxidation tse hlano tse peli le oxide, tin oxide, sex oxide, le manganese dioxide; Ke motsoako oa oxidation dioxide tse hlano le oxide, oxidation tse hlano tse peli le tin oxide, oxidation tse hlano tse peli le manganese oxide le manganese dioxide. Motsoako oa oxidation dioxide ea bosupa ke 0.2: 1: 2: 1. Mehato ea tlhahiso ea li-catalyst tse se nang metsi ke: kopanya silver sulfate, amproof, le multi-oxides ka tekanyo, ebe u eketsa molumo oa metsi a hloekisitsoeng ka makhetlo a 1, fetola boleng ba pH ba sulfuric acid le metsi a ammonia ho 6.5 ho isa ho 7, ebe u eketsa sodium silicine le sodium siliconate le ka tekanyo ea litekanyo. Mashala a masoeu a matšo, a futhumetse mme a hlohlelletsoa ho etsa tharollo e ts'oanang; hlohlelletsa ka bateng ea metsi 'me u kopanye tharollo hore e ome, e omelle ho 100-120 ° C lihora tse 6 ho isa ho tse 8, ebe u baka lihora tse 3 ho isa ho tse 5 ho 400 ~ 450 ° C. 2. Ho lokisa N-hydroxyethylpylpyline (NHP) 1) Kopanya γ-butanol, ethanol e le 'ngoe, le ammonia ka karolelano ea 1.2: 1: 0.2, 'me e arabela ho 0.5MPa le 40 ° C. , Etsa se mahareng; 2) Kenya sefe ea limolek'hule ea 0.1WT % le 0.1WT % ea dilateyl dihal ether ho eketsa mocheso ho 180 ° C ho e etsa hore e omelle ka lihora tse 12 boemong bo bolokiloeng; ho hlalosoa eng e hlalositsoeng; ho boletsoe eng? Sefe ea limolek'hule ke sefe ea limolek'hule ea 10xchemicalbook kapa sefe ea limolek'hule ea 13X. Mokhoa ona o khethoa e le lisefe tsa limolek'hule tse 10x; 3) ho ntsha mokelikeli o fokolang, vacuum ke 0.095MPa, mme e bokella ho ntsha mokelikeli wa ntlha e belang ya 210 ho isa ho 216 ° C. Pyrodorrone; 3. Karabelo ya ho fellwa ke metsi ya N-hydroxyetylpinol ho etsa hore palo ya ho ntsha mokelikeli e fumanweng ha ho lokiswa N-hydroxyethylpinols ka mouoane, e kopantsweng le kgase ya alkaline, dikgase tsa acetylene, le naetrojene ho fumana motswako wa thepa e tala ya kgase. Karolelano e kopantsweng ke 1: 0.5: 0.1: 0.1; Etsa motswako wa thepa e tala ya kgase tlasa boemo ba reactor e tsitsitseng ya catalyst e omileng mochesong wa 350 ° C, kgatello ya 0.01MPa le lebelo la kgase la 50-300H-1, le ho fellwa ke metsi ha metsi ka hara reactor e tsitsitseng ya bethe Catalyst e futhumatswa ho fihlela ho 390 ° C. Kamora hore karabelo ya ho fellwa ke metsi e fihle tekanong, sehlahiswa sa N-ethylene cephalopicone (NVP) se ntshwa ho reactor e tsitsitseng ya bethe. Dikhase tsa alkaline bonyane ke e 'ngoe ea ammonia, methylemine, dihamine, trothalmine le ethimine. Amohela mokhoa oa tlhahlobo ea khase chromatography, o thehiloeng ho γ-butthite e le tekanyetso ea ka hare, ethanol e le li-solvents, o hlahlobile sehlahisoa sa N-ethylene cheedone se lokisitsoeng ke mokhoa ona, o balile sekhahla sa phetoho ea NHP, khetho ea NVP, chelete e kenang ea NVP, eo karolo ea eona ea mohato oa mohato oa khase, eo karolo ea eona ea mohato oa mohato oa khase, eo karolo ea eona ea mohato oa khase e neng e le maemo a teko ea Chromatographic: detector ea TCD, kholomo ea tšepe e sa hloekang, tharollo ea polyacetic glycol tannite e nolofatsang, naetrojene e laetsoe, silicanerization 102 phapang e tšoeu, mocheso oa kamore ea gasification 280 ° C, mocheso oa detector ea TCD 165 ° C, likholomo, likholomo, likholomo Mocheso oa 190 ° C; o baloa ka tlhahlobo ea chromatography ea khase: Sekhahla sa phetoho ea NHP sa 92.8%, khetho ea NVP 91.5%, le chelete e kenang ea NVP ea 85.6%.
