Kusetshenziswa kudayi, kwezokwelapha nakwezinye izinto eziphilayo

Indlela yokukhiqiza:
1. Indlela ye-alkylation ye-ethanol: Gcwalisa i-reactor yebhedi ephefumulayo enomthamo wezingxenye ezingu-400 nge-catalyst ye-H3PO4-SiO2, enendawo yangaphakathi engu-400m2/g, kanye nokuqukethwe kwe-H3PO4 okungu-10%. Ku-evaporator ye-quartz efakwe engxenyeni engezansi yebhedi ephefumulayo, izingxenye ezingu-110 zengxube yale nhlanganisela elandelayo, okungukuthi i-66% o-toluidine kanye ne-34% ethanol [isilinganiso 1:1.2 (isilinganiso se-molar)] yashiswa ku-250°C. Ibhedi ephefumulayo ishiswa ku-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 lingu-80%, u-82.5% we-o-toluidine esabelayo iguqulwa ibe yi-N-ethyl o-toluidine, kanti u-13.1% uguqulwa ube yi-N,N-diethyl o-toluidine. I-alkylating agent ethanol 5% iguqulwa ibe yi-ethylene.

2. Indlela yokusebenzisa i-alkylation ye-Bromoethane? Faka u-40mL (0.37mol) we-o-toluidine kanye no-14mL (0.185mol) we-bromoethane ebhodleleni elinezintamo ezintathu elingu-250mL. Ngemva kokushisa nokuphinde uvuselele amahora ama-2, i-alkalizwa ngesisombululo se-sodium hydroxide esingu-40%. Bese ufaka u-18.5g (0.136mol) we-zinc chloride kanye no-20mL wamanzi esixazululweni se-Chemicalbook, bese uvuselela amahora ama-2.5. I-solid ehlungiwe ikhishwa njalo nge-petroleum ether ku-Soxhlet apparatus, i-extract yagezwa nge-ammonia encibilikisiwe kanye namanzi ancibilikisiwe, i-petroleum ether yashiswa, uketshezi olusele lwancibilikiswa ngaphansi kwengcindezi encishisiwe, kanti i-distillate engu-105~110℃ (4.67kpa) yaqoqwa ukuze kutholakale u-21.1g. Umkhiqizo oqediwe, obalwa njenge-bromoethane, unesivuno esingu-85%.

Isigaba:Ubuthi
Izici zokuvutha kanye nezingozi:iyasha; ukusha kubola igesi enobuthi ye-nitrogen oxide
Izici zokugcina kanye nezokuthutha:Indawo yokugcina impahla inomoya, izinga lokushisa eliphansi futhi yomile; igcinwa futhi ithuthwe ngokwehlukana nama-oxidants, ama-acids, kanye nokudla
I-ejenti yokucisha:i-carbon dioxide, igwebu, impuphu eyomile, isihlabathi
