I-3-Methylaniline (m-toluidine) iwuketshezi olungenambala oluphenduka lube phuzi noma lube nsundu ngokubomvu emoyeni noma ngaphansi kwethonya lokukhanya. Incibilika kancane emanzini, incibilika ku-ethanol ne-ether. Ingahwamuka kanye nomhwamuko wamanzi futhi ikhiqizwa ukusabela kokuncipha kwe-m-nitrotoluene. I-3-Methylaniline isetshenziswa kakhulu njenge-pharmaceutical synthesis intermediate.

Izinhlelo zokusebenza

I-Methylaniline ingenye yama-amine anamakha alula futhi isetshenziswa kabanzi i-organic synthesis intermediate. Isetshenziswa kabanzi njenge-organic synthesis medium for odayi, izibulala-zinambuzane, imithi, njll. Chemicalbook. Njengamanje, ukukhiqizwa kwasekhaya ikakhulukazi kusebenzisa i-nitrotoluene njengempahla eluhlaza, i-ethanol noma i-methanol njenge-solvent, kanye ne-skeleton Ni njenge-catalyst yokwenza ukusabela kwe-hydrogenation ukulungiselela i-methylaniline.

Indlela yokuhlanganisa isebenzisa i-nickel njenge-catalyst ukuze ibangele ukusabela kwe-hydrogenation ye-m-nitrotoluene ku-solvent ye-methanol yezimboni ukuze kukhiqizwe i-m-toluidine. Ngokuhlolwa kwesici esisodwa kanye nokuhlolwa kwe-orthogonal, kusetshenziswa u-80g m-nitrotoluene njengesilinganiso sokubala nangaphansi kwezimo ezigxilile ze-200mL ye-methanol solvent yezimboni, izimo ezilungile zokusabela kwe-Chemicalbook bekuyizi: 2.0g catalyst, isikhathi sokusabela esingu-6h, nezinga lokushisa lokusabela izinga lokushisa ngu-90 ℃, futhi ingcindezi yokusabela ingu-1.6MPa. Okuqukethwe kwe-m-toluidine okutholwe ngaphansi kwalezi zimo kungu-99.79%, okuqukethwe kwengxenye yokukhanya kungu-0.11%, kanti ingxenye esindayo ingu-0.10%
