I-3-Methylaniline (m-toluidine) iwuketshezi olungenambala oluphenduka lube phuzi noma lube nsundu ngokubomvu emoyeni noma ngaphansi kwethonya lokukhanya. Luncibilika kancane emanzini, luncibilika ku-ethanol kanye ne-ether. Lungahwamuka kanye nomhwamuko wamanzi futhi lukhiqizwa ukusabela kokunciphisa kwe-m-nitrotoluene. I-3-Methylaniline isetshenziswa kakhulu njenge-intermediate yokwenziwa kwemithi.

Izicelo

I-Methylaniline ingenye yama-aromatic amine alula kakhulu kanye ne-organic synthesis intermediate esetshenziswa kabanzi. Isetshenziswa kabanzi njenge-organic synthesis intermediate yamadayi, izibulala-zinambuzane, imithi, njll. I-Chemicalbook. Njengamanje, ukukhiqizwa kwasekhaya kusebenzisa kakhulu i-nitrotoluene njengezinto zokusetshenziswa, i-ethanol noma i-methanol njenge-solvent, kanye ne-skeleton Ni njenge-catalyst yokwenza ukusabela kwe-hydrogenation ukulungiselela i-methylaniline.

Indlela yokwenza isebenzisa i-nickel njenge-catalyst ukuze ivuselele ukusabela kwe-hydrogenation kwe-m-nitrotoluene ku-solvent ye-methanol yezimboni ukuze kukhiqizwe i-m-toluidine. Ngokuhlola i-single factor kanye nokuhlolwa kwe-orthogonal, kusetshenziswa i-80g m-nitrotoluene njengesilinganiso sokubala nangaphansi kwezimo ezihleliwe ze-solvent ye-methanol yezimboni engu-200mL, izimo zokusabela ze-Chemicalbook ezinhle kakhulu zaziyi: i-catalyst engu-2.0g, isikhathi sokusabela samahora angu-6, kanye nokushisa kokusabela. Izinga lokushisa lingu-90℃, kanti ingcindezi yokusabela ingu-1.6MPa. Okuqukethwe kwe-m-toluidine okutholwe ngaphansi kwalezi zimo kungu-99.79%, okuqukethwe kwengxenye yokukhanya kungu-0.11%, kanti okuqukethwe kwengxenye esindayo kungu-0.10%.
