3-Methylaniline (m-toluidine) ndi madzi opanda mtundu omwe amasanduka achikasu kapena ofiira abulauni mumlengalenga kapena chifukwa cha kuwala. Kusungunuka pang'ono m'madzi, kusungunuka mu ethanol ndi ether. Ikhoza kusanduka nthunzi pamodzi ndi nthunzi wa madzi ndipo imapangidwa ndi kuchepetsa kachitidwe ka m-nitrotoluene. 3-Methylaniline imagwiritsidwa ntchito makamaka ngati mankhwala apakati.

Mapulogalamu

Methylaniline ndi amodzi mwa ma amine onunkhira osavuta komanso ogwiritsidwa ntchito kwambiri ndi organic synthesis wapakatikati. Amagwiritsidwa ntchito ngati organic kaphatikizidwe wapakatikati kwa utoto, mankhwala ophera tizilombo, mankhwala, etc. Chemicalbook. Pakali pano, zoweta kupanga makamaka ntchito nitrotoluene monga zopangira, Mowa kapena methanol monga zosungunulira, ndi mafupa Ni monga chothandizira kuchita hydrogenation anachita kukonzekera methylaniline.

The kaphatikizidwe njira amagwiritsa faifi tambala monga chothandizira kuti catalyze hydrogenation anachita wa m-nitrotoluene mu mafakitale methanol zosungunulira kupanga m-toluidine. Kupyolera mu kufufuza chinthu chimodzi ndi kuyesa kwa orthogonal, pogwiritsa ntchito 80g m-nitrotoluene monga chiwerengero cha mawerengedwe ndi pansi pa 200mL mafakitale a methanol zosungunulira, mulingo woyenera kwambiri wa Chemicalbook zomwe zimachitika zinali: 2.0g chothandizira, 6h nthawi, ndi kutentha kwa kutentha Kutentha ndi 90 ℃, ndipo kuthamanga kwake ndi 1.6MPa. Zomwe zili m-toluidine zomwe zimapezeka pansi pazimenezi ndi 99.79%, zowunikira ndi 0.11%, ndipo chigawo cholemera ndi 0.10%
