Njira yopangira:
1. Njira ya ethanol alkylation: Lembani bedi lamadzimadzi lokhala ndi mphamvu ya magawo 400 ndi chothandizira cha H3PO4-SiO2, ndi malo amkati a 400m2 / g, ndi H3PO4 ya 10%.Mu evaporator ya quartz yomwe imayikidwa m'munsi mwa bedi lamadzimadzi, magawo 110 a osakaniza zotsatirazi, omwe ndi 66% o-toluidine ndi 34% ethanol [chiŵerengero cha 1: 1.2 (molar ratio)] anasungunuka pa 250 ° C. .Bedi lamadzimadzi limatenthedwa mpaka 330 ° C ndi Chemicalbook.Magawo 108 a condensate amapezedwa pa ola limodzi, zomwe zili mu N-ethyl o-toluidine ndi magawo 60.0, zomwe zili mu N,N-diethyl o-toluidine ndi magawo 10.7, ndi o-toluidine ndi magawo 14.5.Kutembenuka mtima ndi 80%, 82.5% ya o-toluidine anachitapo imasinthidwa kukhala N-ethyl o-toluidine, ndipo 13.1% imasinthidwa kukhala N,N-diethyl o-toluidine.Alkylating agent ethanol 5% imasinthidwa kukhala ethylene.

2. Bromoethane alkylation njira?Onjezani 40mL (0.37mol) ya o-toluidine ndi 14mL (0.185mol) ya bromoethane mu 250mL ya makosi atatu.Pambuyo kutentha ndi refluxing kwa 2h, ndi alkalized ndi 40% sodium hydroxide solution.Kenaka yikani 18.5g (0.136mol) ya zinc chloride ndi 20mL yamadzi mu Chemicalbook solution, ndikuyambitsanso kwa 2.5h.Zolimba zosefedwa zimatulutsidwa mosalekeza ndi petroleum ether mu chipangizo cha Soxhlet, chotsitsacho chinatsukidwa ndi ammonia osungunuka ndi madzi osungunuka, mafuta a petroleum ether adasanduka nthunzi, madzi otsalawo adasungunulidwa pansi pa kupanikizika kochepa, ndi 105 ~ 110 ℃ (4.67kpa) distillate adasonkhanitsidwa kuti apeze 21.1g Chomaliza, chowerengedwa ngati bromoethane, chili ndi zokolola za 85%.

Gulu:Zapoizoni
Kutentha ndi mawonekedwe angozi:kuyaka;kuyaka kumawola mpweya wa nitrogen oxide
Kasungidwe ndi mawonekedwe amayendedwe:nyumba yosungiramo katunduyo imakhala ndi mpweya wokwanira, kutentha kochepa komanso kouma;imasungidwa ndi kutengedwa mosiyana ndi ma okosijeni, zidulo, ndi chakudya
