Ko te 3-Methylaniline (m-toluidine) he wai kore tae ka huri ki te kowhai, ki te whero whero ranei i te rangi, i raro ranei i te awe o te marama. He iti te wairewa ki te wai, ka memeha ki te waiwaro me te etera. Ka taea te whakaeto tahi me te kohu wai ka puta mai i te tauhohenga whakaheke o te m-nitrotoluene. Ko te 3-Methylaniline te nuinga o te whakamahi hei takawaenga whakahiato rongoa.

Nga tono

Ko te Methylaniline tetahi o nga amine kakara tino ngawari me te takawaenga whakahiato waro e whakamahia nuitia ana. E whakamahia nuitia ana hei takawaenga whakahiato waro mo nga waikano, pesticides, rongoa, aha atu. Chemicalbook. I tenei wa, ko te nuinga o nga mahi hanga whare te whakamahi i te nitrotoluene hei rauemi mata, te waihano, te mewaro ranei hei whakarewa, me te kohiwi Ni hei whakakorikori hei mahi i te tauhohenga hauwai hei whakarite i te methylaniline.

Ko te tikanga whakahiato ka whakamahi i te nickel hei whakakorikori hei whakakorikori i te tauhohenga hauwai o te m-nitrotoluene i roto i te whakarewa methanol ahumahi hei whakaputa m-toluidine. Na roto i te whakamatautau tauwehe kotahi me nga whakamatautau orthogonal, ma te whakamahi i te 80g m-nitrotoluene hei tohu tohu tatauranga me nga tikanga pumau o te whakarewa methanol ahumahi 200mL, ko nga tikanga tauhohenga Puka Maama tino pai ko: 2.0g te whakakorikori, 6h te wa tauhohenga, me te pāmahana tauhohenga Ko te 90 te pāmahana. ℃, me te pēhanga tauhohenga he 1.6MPa. Ko te ihirangi m-toluidine i whiwhi i raro i enei tikanga ko te 99.79%, ko te waahanga marama ko te 0.11%, ko te waahanga taimaha he 0.10%
