3-Methylaniline (m-toluidine) imvura isina ruvara inoshanduka yero kana tsvuku tsvuku mumhepo kana pasi pesimba rechiedza. Zvishoma kunyungudika mumvura, soluble mu ethanol uye ether. Inogona kubuda pamwe chete nemhute yemvura uye inogadzirwa nekuderedza kuita kwem-nitrotoluene. 3-Methylaniline inonyanya kushandiswa semishonga synthesis yepakati.

Applications

Methylaniline ndeimwe yeakareruka inonhuhwirira amines uye inoshandiswa zvakanyanya organic synthesis yepakati. Inoshandiswa zvakanyanya se organic synthesis yepakati yedhayi, mishonga yezvipembenene, mishonga, nezvimwewo Chemicalbook. Parizvino, kugadzirwa kwemumba kunonyanya kushandisa nitrotoluene seyakabikwa, ethanol kana methanol se solvent, uye skeleton Ni sechigadziriso chekuita hydrogenation reaction kugadzirira methylaniline.

Iyo synthesis nzira inoshandisa nickel sechinhu chinokonzeresa kuita kwehydrogenation yem-nitrotoluene muindasitiri methanol solvent kugadzira m-toluidine. Kuburikidza nekuongororwa kwechinhu chimwe chete uye orthogonal kuyedza, kushandisa 80g m-nitrotoluene seyekuverenga bhenji uye pasi pezvakatarwa mamiriro e200mL industrial methanol solvent, iyo yakakwana Chemicalbook reaction conditions yaive: 2.0g catalyst, 6h reaction time, uye reaction tembiricha Tembiricha i90 ℃, uye iyo reaction pressure ndeye 1.6MPa. Iyo m-toluidine yemukati inowanikwa pasi pemamiriro aya ndeye 99.79%, iyo chiedza chikamu chiri 0.11%, uye chinorema chikamu chiri 0.10%
