Indlela yokukhiqiza :
1. Indlela ye-Ethanol alkylation: Gcwalisa i-reactor yombhede enomthamo wezingxenye ezingu-400 nge-H3PO4-SiO2 catalyst, enendawo yangaphakathi engu-400m2/g, kanye nokuqukethwe kwe-H3PO4 kuka-10%. Ku-evaporator ye-quartz efakwe engxenyeni engezansi yombhede onoketshezi, izingxenye ezingu-110 zengxube yokwakheka okulandelayo, okungukuthi u-66% o-toluidine kanye no-34% we-ethanol [isilinganiso 1:1.2 (isilinganiso se-molar)] sahwamuka ngo-250°C. . Umbhede omanzi ushisiswe ube ngu-330°C nge-Chemicalbook. Izingxenye ezingu-108 ze-condensate zitholakala ngehora, lapho okuqukethwe kwe-N-ethyl o-toluidine kuyizingxenye ezingu-60.0, okuqukethwe kwe-N,N-diethyl o-toluidine kuyizingxenye ezingu-10.7, kanti okuqukethwe kwe-o-toluidine kuyizingxenye ezingu-14.5. Izinga lokuguqulwa ngu-80%, u-82.5% we-o-toluidine esabelayo iguqulelwa ku-N-ethyl o-toluidine, futhi u-13.1% iguqulelwa ku-N,N-diethyl o-toluidine. I-alkylating agent ethanol 5% iguqulwa ibe yi-ethylene.

2. Indlela ye-Bromoethane alkylation? Engeza u-40mL (0.37mol) we-o-toluidine no-14mL (0.185mol) we-bromoethane ku-250mL yeflask enezintamo ezintathu. Ngemuva kokufudumeza nokushintshashintsha amahora ama-2, i-alkali ngesisombululo se-sodium hydroxide esingu-40%. Bese wengeza u-18.5g (0.136mol) we-zinc chloride kanye no-20mL wamanzi kusixazululo se-Chemicalbook, bese ugoqa amahora angu-2.5. Okuqinile okuhlungiwe kwakulokhu kukhishwa ngokuqhubekayo nge-petroleum ether kumshini we-Soxhlet, okukhishiwe kwagezwa nge-ammonia ehlanjululwe namanzi acwecwe, i-petroleum ether yahwamuka, uketshezi olusele lwancishiswa ngaphansi kwengcindezi encishisiwe, kanye ne-105~110℃ (4.67kpa) i-distillate yaqoqwa ukuze kutholwe u-21.1g Umkhiqizo oqediwe, obalwa njenge-bromoethane, unesivuno esingu-85%.
