ʻO 3-Methylaniline (m-toluidine) he wai waihoʻoluʻu ʻole e huli melemele a ʻulaʻula paha i ka lewa a i ʻole ma lalo o ka mana o ka mālamalama. Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka ethanol a me ka etera. Hiki iā ia ke hoʻoheheʻe pū me ka mahu wai a hana ʻia e ka hopena hoʻemi o ka m-nitrotoluene. Hoʻohana nui ʻia ka 3-Methylaniline ma ke ʻano he pharmaceutical synthesis intermediate.

ʻO ka Methylaniline kekahi o nā amine ʻala maʻalahi loa a me ka hoʻohana nui ʻana o ka synthesis organik. Hoʻohana nui ʻia ʻo ia ma ke ʻano he mea hoʻohuihui kūlohelohe no nā mea kala, pesticides, lāʻau lapaʻau, etc. Chemicalbook. I kēia manawa, hoʻohana nui ka hana home i ka nitrotoluene ma ke ʻano he mea maka, ethanol a i ʻole methanol ma ke ʻano he mea hoʻoheheʻe, a me ka iwi Ni e like me ka catalyst e hana i ka hydrogenation reaction e hoʻomākaukau ai i ka methylaniline.

Hoʻohana ke ʻano hana synthesis i ka nickel ma ke ʻano he catalyst no ka hoʻoulu ʻana i ka hopena hydrogenation o m-nitrotoluene i loko o ka mea hoʻoheheʻe methanol ʻoihana e hana ai i ka m-toluidine. Ma o ka hoʻokolohua kumu hoʻokahi a me nā hoʻokolohua orthogonal, me ka hoʻohana ʻana i ka 80g m-nitrotoluene ma ke ʻano he helu helu helu a ma lalo o nā kūlana paʻa o 200mL ʻoihana methanol solvent, ʻo nā kūlana hoʻohālikelike ʻo Chemicalbook: 2.0g catalyst, 6h manawa pane, a me ka mahana hopena ʻO 90 ka mahana. ℃, a ʻo ke kaomi ʻana he 1.6MPa. ʻO ka ʻike m-toluidine i loaʻa ma lalo o kēia mau kūlana he 99.79%, ʻo ka ʻāpana māmā he 0.11%, a ʻo ka ʻāpana kaumaha he 0.10%
