Igiciro cyiza cy'umusaruro N-VINYL PYRROLIDONE (NVP) CAS 88-12-0

NVP ikoreshwa cyane cyane mu gukora polyvinylpyrrolidone, ikoreshwa cyane mu buvuzi, mu nganda za buri munsi z’imiti n’ibiribwa.

1. Ikoreshwa cyane mu mavuta yo kwisiga, isabune, imiti, ibikoresho byoroshye kubona amafoto n'ibindi bikorwa

2. Ku bikoresho byo gutunganya imisatsi, imiti yica udukoko muri farumasi, nibindi.

Uburyo bwo gutegura N-ethylene pheasone, harimo intambwe zikurikira: 1. Kataloge zaciwe amazi mu gutegura kataloge zaciwe amazi zirimo silver sulfate, sodium aluminium silicate, white charcoal black, amproof, na multi-oxide. Igipimo ni: 0.5 : 5: 3: 5: 10; Muri zo, multi-oxides ni uruvange rungana na gatanu oxidation two -钒 na oxyde, tin oxide, sex oxide, na manganese dioxide; Ni uruvange rwa dioxyde na oxyde tano oxidation, oxidation two -钒 na tin oxide, oxidation two -钒 na manganese oxide na manganese dioxide. Uruvange rwa dioxyde ya karindwi oxidation ni 0.2: 1: 2: 1. Intambwe zo gukora kataloge zaciwe amazi ni: kuvanga silver sulfate, amproof, na multi-oxides mu rugero, hanyuma wongereho inshuro 1 y'amazi yaciwe, hindura pH ya aside sulfurike n'amazi ya ammonia kuri 6.5 kugeza kuri 7, hanyuma wongereho sodium silicine na sodium silicate kandi mu rugero rw'ibipimo. Amakara y'umweru ni umukara, arashyushye kandi aravangwa kugira ngo hakorwe umuti umwe; shyira mu bwogero bw'amazi hanyuma uvange umuti kugira ngo wumuke, wumuke kuri 100-120 ° C mu gihe cy'amasaha 6 kugeza 8, hanyuma uteke amasaha 3 kugeza 5 kuri 400 ~ 450 ° C. 2. Gutegura N-hydroxyethylpylpyline (NHP) 1) Vanga γ-butanol, ethanol imwe, na ammonia ku gipimo cya 1.2: 1: 0.2, kandi ugire ingaruka kuri 0.5MPa na 40 ° C. , Kora intermediate; 2) Shyiramo akayunguruzo ka molekile ka 0.1WT % na 0.1WT % bya dilateyl dihal ether kugira ngo wongere ubushyuhe kugeza kuri 180 ° C kugira ngo amazi agabanuke mu masaha 12; ni iki kivugwa nk'uko kivugwa; ni iki kivugwa? Akayunguruzo ka molekile ni akayunguruzo ka molekile ka 10xchemicalbook cyangwa akayunguruzo ka molekile ka 13X. Ubu buryo butoranywa nk'akayunguruzo ka molekile ka 10x; 3) Gukuraho ubushyuhe, icyuma gitanga umwuka ni 0.095MPa, kandi gikusanya ubushyuhe bwo kubira bwa 210 kugeza 216 ° C. Pyrodorrone; 3. Uburyo N-hydroxyetylpinol ikora kugira ngo ikore amanota yo kugabanya ubushyuhe aboneka mu gutegura N-hydroxyethylpinols mu mwuka, uvanze na gaze ya alkaline, gaze ya acetylene, na azote kugira ngo haboneke uruvange rw'ibikoresho by'imyuka. Igipimo cy'imyuka kivanze ni 1: 0.5: 0.1: 0.1; Kora uruvange rw'ibikoresho by'imyuka munsi y'imiterere y'icyuma gifata amazi cya catalyst yakuwemo amazi ku bushyuhe bwa 350 ° C, umuvuduko wa 0.01MPa n'umuvuduko wa gaze wa 50-300H-1, hamwe n'ubushyuhe bwo kugabanya amazi mu cyuma gifata amazi cya catalyst ishyushye kugeza kuri 390 ° C. Nyuma y'uko ubushyuhe bwo kugabanya amazi bugeze ku rugero, umusaruro wa N-ethylene cephalopicone (NVP) usohoka mu cyuma gifata amazi cyakuwemo amazi. Imyuka ya alkaline ni nibura imwe muri ammonia, methylemine, dihamine, trothalmine, na ethimine. Koresha uburyo bwo gusesengura chromatography ya gaz, bushingiye kuri γ-buthite nk'igipimo cy'imbere, ethanol nk'ibishongesha, wasesenguye umusaruro wa N-ethylene cheedone wateguwe n'ubu buryo, wabaze igipimo cyo guhindura NHP, guhitamo NVP, inyungu ya NVP, aho gazi ingana, aho gazi ingana, aho gazi ingana. Imiterere y'ibizamini bya chromatographic: TCD detector, steel stainless column, poly acetic glycol tannite dilate fixing solution, azote yuzuye, silicanerization 102 white contrast, gasification room bushyuhe 280 ° C, TCD detector bushyuhe 165 ° C, inkingi, inkingi, inkingi Ubushyuhe bwa 190 ° C; bwabazwe hakoreshejwe isesengura rya chromatography ya gaz: igipimo cyo guhindura NHP cya 92.8%, NVP selectivity 91.5%, n'inyungu ya NVP ya 85.6%.
