Kugadzira nzira:
1. Ethanol alkylation method: Zadza bhedha yakasvibiswa ine simba rezvikamu zve 400 neH3PO4-SiO2 catalyst, ine nzvimbo yemukati ye 400m2 / g, uye H3PO4 zvinyorwa zve10%. Mune evaporator yequartz yakaiswa muchikamu chezasi chemubhedha wakanyungudika, 110 zvikamu zvemusanganiswa weiyo inotevera kuumbwa, zvinoti 66% o-toluidine uye 34% ethanol [reshiyo 1:1.2 (molar ratio)] yakanyungudika pa250°C. . Mubhedha wakanyungudika unodziiswa kusvika 330°C ne Chemicalbook. 108 zvikamu zve condensate zvinowanikwa paawa, izvo zvinyorwa zveN-ethyl o-toluidine zvikamu 60.0, zvinyorwa zveN, N-diethyl o-toluidine zvikamu 10.7, uye zvinyorwa zve o-toluidine zvikamu 14.5. Chiyero chekushandura i80%, 82.5% ye-o-toluidine yakabatwa inoshandurwa kuva N-ethyl o-toluidine, uye 13.1% inoshandurwa kuva N, N-diethyl o-toluidine. Alkylating agent ethanol 5% inoshandurwa kuita ethylene.

2. Bromoethane alkylation nzira? Wedzera 40mL (0.37mol) ye o-toluidine uye 14mL (0.185mol) yebromoethane mu250mL ine mitsipa mitatu. Mushure mekupisa uye kudzoreredza kwemaawa maviri, inogadziriswa ne40% sodium hydroxide solution. Wobva wawedzera 18.5g (0.136mol) yezinc chloride uye 20mL yemvura muChemicalbook solution, uye simbisa kwe2.5h. Iyo yakasimba yakasefa yairamba ichibudiswa nepetroleum ether mumidziyo yeSoxhlet, iyo yakabviswa yakagezwa nedilute ammonia uye yakanyungudutswa mvura, iyo petroleum ether yakanyungudutswa, mvura yakasara yakanyungudutswa pasi pekumanikidzwa kwakaderedzwa, uye 105 ~ 110 ℃ (4.67kpa) distillate yakaunganidzwa kuti iwane 21.1g Chigadzirwa chakapedzwa, chakaverengerwa sebromoethane, chine goho re85%.
