Indlela yokuvelisa:
1. Indlela ye-alkylation ye-ethanol: Zalisa i-reactor yebhedi emanzi enomthamo weenxalenye ezingama-400 nge-catalyst ye-H3PO4-SiO2, enommandla wangaphakathi we-400m2/g, kunye nomxholo we-H3PO4 we-10%. Kwi-evaporator ye-quartz efakwe kwinxalenye esezantsi yebhedi emanzi, iinxalenye ezili-110 zomxube wolu hlobo lulandelayo, oluyi-66% ye-o-toluidine kunye ne-34% ye-ethanol [umlinganiselo 1:1.2 (umlinganiselo we-molar)] zatshiswa kwi-250°C. Ibhedi emanzi itshiswa ukuya kwi-330°C ngeChemicalbook. Iinxalenye ezili-108 ze-condensate zifunyanwa ngeyure, apho umxholo we-N-ethyl o-toluidine uyinxalenye engama-60.0, umxholo we-N,N-diethyl o-toluidine uyinxalenye ezili-10.7, kwaye umxholo we-o-toluidine uyinxalenye ezili-14.5. Izinga lokuguqulwa yi-80%, i-82.5% ye-o-toluidine esabelayo iguqulwa ibe yi-N-ethyl o-toluidine, kwaye i-13.1% iguqulwa ibe yi-N,N-diethyl o-toluidine. I-alkylating agent ethanol 5% iguqulwa ibe yi-ethylene.

2. Indlela yokusebenzisa i-alkylation yeBromoethane? Yongeza i-40mL (0.37mol) ye-o-toluidine kunye ne-14mL (0.185mol) ye-bromoethane kwiflaski ene-three-necked engama-250mL. Emva kokufudumeza nokuhlambulula i-reflux iiyure ezi-2, i-alkalized ngesisombululo se-sodium hydroxide esingama-40%. Emva koko yongeza i-18.5g (0.136mol) ye-zinc chloride kunye ne-20mL yamanzi kwisisombululo seChemicalbook, uze uxube iiyure ezi-2.5. I-filtered solid ikhutshwa rhoqo nge-petroleum ether kwisixhobo seSoxhlet, i-extract yahlanjwa nge-dilute ammonia kunye namanzi acocekileyo, i-petroleum ether yatshiswa, ulwelo oluseleyo lwanyibilikiswa phantsi koxinzelelo oluncitshisiweyo, kwaye i-distillate ye-105~110℃ (4.67kpa) yaqokelelwa ukuze kufunyanwe i-21.1g. Imveliso egqityiweyo, ebalwe njenge-bromoethane, inesivuno se-85%.

Udidi:Ityhefu
Iimpawu zokutsha kunye nobungozi:iyatsha; ukutsha kuyayibolisa igesi ye-nitrogen oxide enobuthi
Iimpawu zokugcina kunye nezothutho:Indawo yokugcina izinto inemoya opholileyo, ishushu kwaye yomile; igcinwa kwaye ithuthwe ngokwahlukileyo kwii-oxidants, ii-asidi, kunye nokutya
Iarhente yokucima umlilo:ikhabhoni diokside, igwebu, umgubo owomileyo, isanti
