I-3-Methylaniline (m-toluidine) lulwelo olungenambala olujika lube tyheli okanye lubomvu bumdaka emoyeni okanye phantsi kweempembelelo zokukhanya. Inyibilika kancinci emanzini, inyibilika kwi-ethanol kunye ne-ether. Iyakwazi ukuphuphuma kunye nomphunga wamanzi kwaye iveliswe kukusabela kokuncipha kwe-m-nitrotoluene. I-3-Methylaniline isetyenziswa kakhulu njenge-pharmaceutical synthesis intermediate.

Usetyenziso

I-Methylaniline yenye yezona zinto zilula ezinuka kamnandi kunye ne-organic synthesis ephakathi. Isetyenziswa ngokubanzi njenge-organic synthesis intermediate kwiidayi, izibulala-zinambuzane, amayeza, njl. Okwangoku, imveliso yasekhaya ikakhulu isebenzisa i-nitrotoluene njengento ekrwada, i-ethanol okanye i-methanol njenge-solvent, kunye ne-skeleton ye-Ni njenge-catalyst yokwenza i-hydrogenation reaction ukuze ilungiselele i-methylaniline.

Indlela yokudibanisa isebenzisa i-nickel njenge-catalyst yokwenza i-hydrogenation reaction ye-m-nitrotoluene kwi-industrial methanol solvent ukuvelisa i-m-toluidine. Ngovavanyo lwento enye kunye novavanyo lwe-orthogonal, kusetyenziswa i-80g m-nitrotoluene njengomlinganiselo wokubala naphantsi kweemeko ezimiselweyo ze-200mL ye-methanol ye-solvent ye-methanol yoshishino, iimeko ezifanelekileyo zokuphendula i-Chemicalbook yaba: 2.0g catalyst, 6h ixesha lokuphendula, kunye nobushushu bokuphendula Ubushushu ngama-90 ℃, kunye noxinzelelo lokusabela yi-1.6MPa. Umxholo we-m-toluidine ofunyenwe phantsi kwezi meko ngu-99.79%, umxholo wecandelo lokukhanya ngu-0.11%, kwaye umxholo wecandelo elinzima ngu-0.10%
