3-Methylaniline (m-toluidine) waa dareere aan midab lahayn oo isu beddela huruud ama bunni guduudan hawada ama iftiinka iftiinka. Waxoogaa ku milmay biyaha, ku milmay ethanol iyo ether. Waxa ay la soo bixi kartaa uumiga biyaha waxaana soo saara falcelinta dhimista m-nitrotoluene. 3-Methylaniline waxaa inta badan loo isticmaalaa sidii dhexdhexaad ka mid ah farmasiga.

Codsiyada

Methylaniline waa mid ka mid ah aminyada udgoonka ugu fudud iyo dhex dhexaad ka samaysan organic si weyn loo isticmaalo. Waxa si weyn loogu isticmaalaa sida dhex dhexaad ka samaysan organic ee dheeha, sunta cayayaanka, daawooyinka, iwm. Kiimikada. Waqtigan xaadirka ah, wax soo saarka gudaha inta badan waxay u isticmaashaa nitrotoluene sida walxo ceeriin ah, ethanol ama methanol sida dareere ah, iyo qalfoofka Ni sida kicinta si loo sameeyo falcelinta hydrogenation si loogu diyaariyo methylaniline.

Habka isku-dubaridku wuxuu u adeegsadaa nikkel sida kicinta si uu u kiciyo falcelinta hydrogenation-ka ee m-nitrotoluene ee dareeraha methanol warshadaha si loo dhaliyo m-toluidine. Iyada oo loo marayo baaritaanka hal arrin iyo tijaabooyinka orthogonal, iyadoo la adeegsanayo 80g m-nitrotoluene sida qiyaasta xisaabinta iyo xaaladaha go'an ee 200mL dareeraha methanol warshadaha, xaaladaha falcelinta kiimikada ugu fiican waxay ahaayeen: 2.0g kicinta, 6h waqtiga falcelinta, iyo heerkulka falcelinta Heerkulka waa 90 ℃, iyo cadaadiska falcelintu waa 1.6MPa. Maaddada m-toluidine ee lagu helay xaaladahan waa 99.79%, ka kooban iftiinku waa 0.11%, iyo ka kooban yahay 0.10%
