Hoʻohana nui ʻia ʻo NVP e hana i ka polyvinylpyrrolidone, kahi i hoʻohana nui ʻia ma nā kahua o ka lāʻau lapaʻau, nā kemika o kēlā me kēia lā a me ka ʻoihana meaʻai.

1. Hoʻohana nui ʻia i nā mea hoʻonani, nā detergents, nā lāʻau lapaʻau, nā mea photosensitive a me nā mahina ʻē aʻe

2. No nā gels hoʻonaninani lauoho, nā mea hoʻopau lāʻau lapaʻau, a pēlā aku.

ʻO ke kaʻina hana hoʻomākaukau o ka N-ethylene pheasone, me kēia mau ʻanuʻu: 1. ʻO nā mea hoʻouluulu maloʻo o ka hoʻomākaukau ʻana o ka mea hoʻouluulu maloʻo he kālā sulfate, sodium aluminum silicate, keʻokeʻo charcoal ʻeleʻele, amproof, a me multi-oxide. ʻO ka lakio: 0.5: 5: 3: 5: 10; I waena o lākou, ʻo ka multi-oxides he ʻelima mau hui o ʻelima oxidation ʻelua -钒 a me oxide, tin oxide, sex oxide, a me manganese dioxide; He hui ia o ʻelima oxidation dioxide a me oxide, ʻelima oxidation ʻelua -钒 a me tin oxide, ʻelima oxidation ʻelua -钒 a me manganese oxide a me manganese dioxide. ʻO ka hui ʻana o ka hiku o ka oxidation dioxide he 0.2: 1: 2: 1. ʻO nā ʻanuʻu hana o nā mea hoʻouluulu maloʻo: e hui pū i ke kālā sulfate, amproof, a me multi-oxides i ka nui, a laila e hoʻohui i ka 1 manawa o ka nui o ka wai distilled, e hoʻoponopono i ka waiwai pH o ka sulfuric acid a me ka wai ammonia i 6.5 a 7, a laila e hoʻohui i ka sodium silicine a me ka sodium siliconate a i ka nui. ʻEleʻele ka lanahu keʻokeʻo, hoʻomehana ʻia a hoʻoulu ʻia e hana i ka hopena like; e hoʻoulu i loko o ka ʻauʻau wai a hoʻomāʻū 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. Hoʻomākaukau ʻana o N-hydroxyethylpylpyline (NHP) 1) E kāwili i ka γ-butanol, hoʻokahi ethanol, a me ka ammonia ma ka lakio o 1.2: 1: 0.2, a pane ma 0.5MPa a me 40 ° C. , E hana i kahi waena; 2) E hoʻohui i ka sieve 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 i ke kūlana paʻa; he aha ka mea i wehewehe ʻia e like me ka mea i wehewehe ʻia; he aha ka mea i ʻōlelo ʻia? ʻO ka sieve molekala he 10xchemicalbook molecular sieve a i ʻole 13X molekala sieve. Ua koho ʻia kēia ʻano hana he 10x molekala sieves; 3) ka distillation decompression, ʻo ka vacuum he 0.095MPa, a hōʻiliʻili i ka distillation o ka paila o 210 a 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 ka hui ʻana o nā mea maka kinoea. ʻO ka lakio hui ʻia he 1: 0.5: 0.1: 0.1; Hana i ka hui ʻana o nā mea maka kinoea ma lalo o ke kūlana o kahi reactor moe paʻa o ka catalyst dehydrated ma ka mahana o 350 ° C, ke kaomi o 0.01MPa a me ka wikiwiki o ke kinoea o 50-300H-1, a me ka dehydration o ka dehydration i loko o ka reactor moe paʻa. Hoʻomehana ʻia ka catalyst i 390 ° C. Ma hope o ka hiki ʻana o ka hopena dehydration i ke kaulike, hoʻokuʻu ʻia ka huahana N-ethylene cephalopicone (NVP) mai kahi reactor moe paʻa. ʻO nā kinoea alkaline ma ka liʻiliʻi he hoʻokahi o ka ammonia, methylemine, dihamine, trothalmine, a me ka ethimine. Hoʻohana i ke ʻano loiloi chromatography gas, ma muli o ka γ-butthite ma ke ʻano he kūlana kūloko, ethanol ma ke ʻano he solvents, kālailai i ka huahana N-ethylene cheedone i hoʻomākaukau ʻia e kēia ʻano hana, helu ʻia ka helu hoʻololi NHP, NVP selectivity, NVP loaʻa kālā, o ia hoʻi ke kinoea pae pae pae, o ia hoʻi ke kinoea pae pae pae, o ia hoʻi ke kinoea pae pae. Nā kūlana hoʻāʻo Chromatographic: TCD detector, stainless steel column, poly acetic glycol tannite dilate fixing solution, ua hoʻouka ʻia ka nitrogen, silicanerization 102 keʻokeʻo ʻokoʻa, gasification room temperature 280 ° C, TCD detector temperature 165 ° C, kolamu, kolamu, kolamu ʻO ka mahana o 190 ° C; helu ʻia e ka nānā ʻana o ka chromatography gas: NHP conversion rate of 92.8%, NVP selectivity 91.5%, a me NVP loaʻa kālā o 85.6%.
