Tikanga whakaputa:
1. Tikanga ethanol alkylation: Whakakiia he reactor moenga wai me te kaha o nga wahanga 400 ki te H3PO4-SiO2 catalyst, me te waahanga o roto o te 400m2 / g, me te ihirangi H3PO4 o 10%. I roto i te whakaetonga kiripaka i whakauruhia ki te taha o raro o te moenga wai, 110 nga wahanga o te ranunga o te hanganga e whai ake nei, ara ko te 66% o-toluidine me te 34% te ethanol [wwehenga 1:1.2 (molar ratio)] i whakaeto i te 250°C . Ka whakamahanahia te moenga wai ki te 330°C me te Chemicalbook. 108 nga wahanga o te condensate e whiwhi ana i ia haora, e 60.0 nga wahanga o te N-ethyl o-toluidine, 10.7 nga wahanga o te N,N-diethyl o-toluidine, 14.5 nga wahanga o te o-toluidine. Ko te tere o te hurihanga ko te 80%, ko te 82.5% o te o-toluidine tauhohe ka huri ki te N-ethyl o-toluidine, me te 13.1% ka hurihia hei N,N-diethyl o-toluidine. Ka hurihia te ethanol 5% ki te ethylene.

2. Te tikanga whakamaoritanga Bromoethane? Tāpirihia te 40mL (0.37mol) o-toluidine me te 14mL (0.185mol) o te bromoethane ki roto i te ipu 250mL toru-kaki. I muri i te whakamahana me te whakamaarama mo te 2h, ka whakamaarama ki te 40% wairewa konutai wai. Kātahi ka tāpirihia te 18.5g (0.136mol) o te konutea pūhaumāota me te 20mL o te wai ki roto i te wairewa Puka Matū, ka kōrori i te 2.5h. Ko te totoka kua tātarihia i tangohia tonutia me te hinu etera i roto i te taputapu Soxhlet, ka horoia te tangohanga ki te haukini waimeha me te wai marumaru, ka whakaeto te hinu hinu, ka whakahekehia te toenga wai i raro i te pehanga iti, me te 105~110 ℃ (4.67kpa) I kohia te distillate ki te whiwhi 21.1g Ko te hua kua oti, kua kiia hei bromoethane, he 85%.

Kāwai:paitini
Te mura me nga ahuatanga morearea:mura ahi; ka pirau te ngingiha hau hauota waikura paitini
Nga ahuatanga rokiroki me te kawe:he hau te whare putunga, he iti te pāmahana me te maroke; ka rongoatia, ka haria motuhake mai i nga waikura, waikawa, me te kai
Kaipatu tinei:hauhā, pahuka, paura maroke, onepu
