ʻO ke kaʻina hana hoʻomākaukau o ka N-ethylene pheasone, me kēia mau ʻanuʻu: 1. ʻO nā catalysts dehydrated o ka hoʻomākaukau ʻana i ka catalyst dehydrated i loko o ke kālā sulfate, sodium aluminika silicate, keʻokeʻo lanahu ʻeleʻele, amproof, a me multi-oxide.ʻO ka māhele: 0.5 : 5: 3: 5: 10;Ma waena o lākou, ʻo ka multi-oxides he ʻelima hui ʻana o ʻelima oxidation ʻelua -钒 a me ka oxide, tin oxide, sex oxide, a me manganese dioxide;He hui ia o elima oxidation dioxide a me oxide, elima oxidation elua -钒 a tin oxide, elima oxidation elua -钒 a me manganese oxide a me manganese dioxide.ʻO ka hui ʻana o ka hiku o ka oxidation dioxide ʻo 0.2: 1: 2: 1. ʻO nā ʻanuʻu hana o nā catalysts dehydrated ʻo ia: hui pū i ka sulfate kālā, amproof, a me nā multi-oxides ma ke ʻano, a laila e hoʻohui i 1 mau manawa o ka nui o ka wai distilled, hoʻoponopono i ka pH ka waiwai o ka sulfuric acid a me ka wai amonia i 6.5 a 7, a laila e hoʻohui i ka sodium silicine a me ka sodium siliconate a ma ke ʻano like ʻole.He ʻeleʻele ka lanahu keʻokeʻo, wela a hoʻoulu ʻia e hana i ka hopena like ʻole;e hoʻoulu i ka wai ʻauʻau a condense i ka hopena e maloʻo, maloʻo ma 100-120 ° C no 6 a 8h, a laila e hoʻomoʻa no 3 a 5h ma 400 ~ 450 ° C. 2. Ka hoʻomākaukau ʻana o N-hydroxyethylpylpyline (NHP) 1) Hoʻohui i ka γ-butanol, hoʻokahi ethanol, a me ka amonia ma ka ratio o 1.2: 1: 0.2, a hana i ka 0.5MPa a me 40 ° C., E hana i waena;2) E hoʻohui i ka kānana molekala o 0.1WT % a me 0.1WT % o ka dilateyl dihal ether e hoʻonui i ka mahana i 180 ° C e hoʻomaloʻo ʻia e 12h ma kahi kūlana paʻa;ka mea i wehewehe ʻia e like me ka mea i wehewehe ʻia;he aha ka mea i oleloia?ʻO ka kānana molekala he 10xchemicalbook molecular sieve a i ʻole 13X molecular sieve.Ua koho ʻia kēia ʻano he 10x molecular sieves;3) decompression distillation, o ka vacuum mea 0.095MPa, a ohi i ka distillation o ka paila wahi o 210 i 216 ° C. Pyrodorrone;3. ʻO ka hopena dehydration o N-hydroxyetylpinol e hana i ka helu distillation i loaʻa i ka hoʻomākaukau ʻana o N-hydroxyethylpinols i loko o ka mahu, i hui pū ʻia me ke kinoea alkaline, nā kinoea acetylene, a me ka nitrogen e loaʻa ai ke kinoea maka.ʻO ka ratio hui ʻia ʻo 1 : 0.5: 0.1: 0.1;E hana i ke kinoea maka i hui ʻia ma lalo o ke ʻano o kahi reactor moe paʻa o ka catalyst dehydrated ma kahi mahana o 350 ° C, ke kaomi o 0.01MPa a me ka wikiwiki kinoea o 50-300H-1, a me ka dehydration o ka dehydration i ka paʻa. hoʻomoe moe Hoʻomaʻamaʻa ʻia ka catalyst i 390 ° C. Ma hope o ka hiki ʻana o ka hopena dehydration i ke koena, hoʻokuʻu ʻia ka huahana N-ethylene cephalopicone (NVP) mai kahi reactor moe paʻa.ʻO nā kinoea alkaline ma kahi liʻiliʻi o ka ammonia, methylemine, dihamine, trothalmine, a me ethimine.Hoʻohana i ke ʻano loiloi chromatography kinoea, e pili ana i ka γ-butthite e like me ke kūlana kūloko, ethanol e like me nā mea hoʻoheheʻe, hoʻopaʻa ʻia i ka huahana N-ethylene cheedone i hoʻomākaukau ʻia e kēia ʻano, helu i ka helu hoʻololi NHP, NVP selectivity, NVP loaʻa, nona ka pae kinoea. 'āpana 'āpana, 'o ia ka 'āpana kinoea 'āpana 'āpana 'āpana, 'o ia ke kinoea 'āpana 'ano ho'ā'o Chromatographic: TCD mea 'ike, kuhili 'ole kolamu, poly acetic glycol tannite dilate ho'oponopono ho'oponopono, naikokene ua hoouka, silicanerization 102 ke'oke'o like 'ole, gasification lumi wela 280 ° C, TCD detector wela 165 ° C, kolamu, kolamu, kolamu ʻO ka mahana o 190 ° C;helu ʻia e ka nānā ʻana o ka chromatography kinoea: NHP huli ʻana o 92.8 %, NVP selectivity 91.5 %, a me NVP loaʻa o 85.6 %.
