2. Mo nga makawe o nga makawe, he aukati i te rongoā, me etahi atu

Ko te tukanga whakarite i te N-Ethylene Pheasone, tae atu ki nga waahanga e whai ake nei: Te rahiraa ra: 0.5: 5: 5: 5: 10 I roto ia ratou, e rima nga waahanga mo te rima o nga tohu e rima - e rima nga waahanga, ko te oriwa, ko te oriwa, ko te oriwa, ko te hauraro; Ko te ranunga mo te rima o te hinu me te hinu, me te oko e rima: Ko te ranunga o te konutai tuawhitu ko te 0.2: 1: 1. 1 Te uara o te waikawa whanariki me te wai haukinia ki te 6.5 ki te 7, a ka whakauru i te konutai konutai me te konutai silicoonate me te rahi Tuhinga o mua. He mangu ma te ma ma, he wera, ka whakaohooho kia pai ai te otinga whakakotahi; Oho i roto i te pati wai me te whakakore i te otinga kia maroke, maroke i te 100-120 ° C mo te 6 ki te 8h, ka tunua mo te 4 ki te 4H Whakaranu γ-Bennol, kotahi etanol, me te haukinia i te paanga o te 1.2: 1: 1: 0.2, a ka tau ki te 0.5mpa me te 40 ° C., Hanga he takawaenga; 2) Tāpirihia te tatari o te pikaunga o te 0.1WT% me te 0.1WT% o te eter dilateyl dihal hei whakapiki i te pāmahana ki te 180 ° C kia pai ai te 12h i roto i te whenua pumau; te mea e whakaahuatia ana kua whakaahuatia; He aha te mea kua whakahuahia? Ko te tatari o te koriri he 10xchemicalbook abouth lescular side or 13x noa te piine. Kua tohua tenei tikanga hei tiihi ngota 10x; 3) Ko te Huringa decompress, ko te waatea ko te 0.095mpa, ka kohia te huringa o te kohua kohua 210 ki te 216 ° C. Pyrodorrone; 3. Ko te tauhohenga mate o te n-hydroxyetylpinol hei hanga i te tohu hurihuri i whiwhi ki te a--hydroxythylpinols ki te mama, whakaranuhia ki te hau hauota. Ko te ōwehenga whakaranu he 1: 0.5: 0.1: 0.1; Whakaritea te ranunga rauemi raw ngoikore i raro i te ahuatanga o te kaimekemeke kua oti te whakarite i te pāmahana o te dehydrated i te pāmahana o te 35,01mpa me te tere o te hau o te defydration i roto i te tuma Ka rewa te moenga o te moenga ki te 390 ° C. I muri i te tauhohenga o te reanga kua tae atu ki te pauna, te n-ethlene Ko te hua a Cephalopicone (NVP) ka tukuna mai i te reeti moenga. Ko nga hau a te alkaline he iti rawa tetahi o nga haukini, methlemine, te dihanine, te trothalmine, me te Ethimine. Ko te tikanga tātari chromotteris hau, e pa ana ki te paerewa a-roto, ko te etanolne cheedone i whakaritehia e te N-Ethylene Cheedone. Wāhanga Wahanga, no reira ko wai te waahanga hiko o te waahanga waahanga waahanga, ko wai te waahanga hiko o te hau chromatographic: TCD Kaituku TCD, ko te pou kowhatu kowiri, poly Acetic Tannite te whakatika i te otinga, ka utaina te hauota tekau ma te pāmahana. Ka kiia e te tātaritanga o te kromatographer hau: NHP te tere o te hurihanga o te 92.8%, NVP te tohu 91.5%, me nga moni NVP.
