Makhalidwe
2,4,6-Trimethylaniline ndi yapakatikati yomwe imagwiritsidwa ntchito kwambiri mu utoto, mankhwala ophera tizilombo ndi mafakitale ena.Zopangira zopangira mesitidine ndi mesitylene, yomwe imapezeka mu petroleum.Pozindikira kupanga mafakitale akuluakulu ku China, kutulutsa kwa mesitylene kwapitirizabe kuwonjezeka, kotero kuti chitukuko cha zinthu zake zotsika pansi chalandira chidwi kwambiri.Zomwe zili pansi pa mtsinje wa mesitylene, monga trimellitic acid, mesitidine, ndi M acid, zonse ndi mankhwala ofunika kwambiri.Mesitylene amagwiritsidwa ntchito ngati zopangira kupanga mesitidine.Mchitidwe wa nitration wa mesitylene ndiye chinsinsi, chomwe chimagwirizana mwachindunji ndi mtengo wopangira komanso mtundu wazinthu.
Kugwiritsa ntchito
Chopangidwa choyera cha mesitidine ndi madzi opanda mtundu komanso owoneka bwino akakhala ndi mpweya, ndipo zimakhala zosavuta kusintha mtundu, ndipo nthawi zambiri zimakhala zofiirira.Sasungunuke m'madzi, sungunuka mu zosungunulira organic monga ethanol ndi ether.Mesitylene ndi wapakatikati wa utoto, utoto wamitundu ndi mankhwala ophera tizilombo.Makamaka ntchito synthesis wa utoto.Ndilo lapakati la ofooka asidi brilliant blue RAW.Ndiwo wapakatikati wa utoto wofooka wa asidi Praslin RAW.
Kukonzekera
1) Mu 50 mL yosalekeza kutsitsa mphamvu, choyamba onjezerani 10 g wa asidi acetic, kenaka onjezerani 13.5 g wa 98% nitric acid, imani ndi kuziziritsa pansi pa 25 ° C. kuti mugwiritse ntchito.Mu botolo la 250 mL la makosi anayi, onjezerani 24.5 g wa acetic anhydride ndi 24 g wa mesitylene motsatizana, ndipo onjezerani nitric acid solution dropwise pamene mukugwedeza pa 20-25 ° C.Kudontha kukamalizidwa, sungani pa 0~25℃ kwa 2h mu 2Chemicalbook, kenako kwezani mpaka 35℃ 40℃ ndikuyisunga kwa 2h.Sampling idayesedwa ndi chromatograph yamadzimadzi, ndipo mesitylene itapezeka, zomwe zidathetsedwa.Ma reaction equation ndi awa:
2) Pambuyo pa chithandizo cha nitrification reaction Pali njira ziwiri zazikulu zopangira mankhwala a nitrification reaction, kutsuka madzi ndi distillation.Njira yotsuka madzi: Pambuyo pakutha kwa nitration, onjezerani madzi pafupifupi 40g mu botolo, kwezani kutentha mpaka 65 ℃, alekanitse zigawo pamene kuli kotentha, sambani ndi madzi otentha 65 ℃ kwa 2 mpaka 3, gawo la organic. ndi nitro mesitylene.Njira ya distillation: Nitration ikatha, kutentha kumakwera kufika 70-80 ° C, ndiyeno asidi amachotsedwa ndi vacuum distillation kuti apeze nitro mesitylene.
