Gaosiga auala:
1. Metotia alkylation ethanol: Faatumu se reactor moega fluidized ma se gafatia o vaega 400 ma H3PO4-SiO2 catalyst, faatasi ai ma se vaega i luga o le 400m2 / g, ma se H3PO4 mea o le 10%.I totonu o se quartz evaporator faʻapipiʻiina i le pito i lalo o le moega faʻafefe, 110 vaega o le faʻafefiloi o mea nei, e taʻua o le 66% o-toluidine ma le 34% ethanol [ratio 1:1.2 (molar ratio)] na faʻafefe i le 250 ° C. .O le moega fa'asuavaia e fa'avevela i le 330°C ma le Chemicalbook.108 vaega o le condensate e maua i le itula, lea o le anotusi o le N-ethyl o-toluidine e 60.0 vaega, o le anotusi o le N,N-diethyl o-toluidine o le 10.7 vaega, ma le anotusi o le o-toluidine e 14.5 vaega.O le fua faatatau o le liua o le 80%, 82.5% o le o-toluidine fa'afoliga ua liua i le N-ethyl o-toluidine, ma le 13.1% ua liua i le N,N-diethyl o-toluidine.Alkylating agent ethanol 5% ua liua i le ethylene.

2. Bromoethane alkylation auala?Faaopopo le 40mL (0.37mol) o le o-toluidine ma le 14mL (0.185mol) o le bromoethane i totonu o se fagu 250mL tolu-ua.A maeʻa le faʻamafanafanaina ma le faʻafefe mo le 2h, e faʻasalaina i le 40% sodium hydroxide solution.Ona faaopoopo lea o le 18.5g (0.136mol) o le zinc chloride ma le 20mL o le vai i totonu o le vaifofo o le Chemicalbook, ma faʻafefe mo le 2.5h.O le faʻamaʻa faʻamamaina sa faʻaauau pea ona faʻaaogaina ma le suauʻu ether i totonu o se masini Soxhlet, o le faʻasalaga na fufuluina i le ammonia faʻafefe ma vai faʻafefe, o le suauʻu ether na faʻafefe, o le vai na totoe na faʻafefe i lalo o le faʻaitiitia o le mamafa, ma le 105 ~ 110 ℃ (4.67kpa) distillate na aoina e maua ai le 21.1g O le oloa maeʻa, fuafuaina o le bromoethane, e maua ai le 85%.
