3-Methylaniline (m-toluidine) yog cov kua tsis muaj xim uas hloov daj lossis xim av liab hauv huab cua lossis nyob rau hauv lub teeb. Me ntsis soluble hauv dej, soluble hauv ethanol thiab ether. Nws tuaj yeem ua pa nrog cov dej pa thiab yog tsim los ntawm kev txo qis ntawm m-nitrotoluene. 3-Methylaniline feem ntau yog siv ua cov tshuaj synthesis intermediate.

Cov ntawv thov
Methylaniline yog ib qho ntawm cov amines aromatic yooj yim tshaj plaws thiab yog ib qho siv dav hauv kev tsim cov organic synthesis intermediate. Nws yog dav siv ua cov organic synthesis intermediate rau cov xim, tshuaj tua kab, tshuaj, thiab lwm yam. Tam sim no, kev tsim khoom hauv tsev feem ntau siv nitrotoluene ua cov khoom siv raw, ethanol lossis methanol ua cov kuab tshuaj, thiab pob txha Ni ua catalyst los ua cov tshuaj hydrogenation los npaj methylaniline.
Txoj kev tsim cov tshuaj siv nickel ua tus catalyst los ua kom cov tshuaj hydrogenation ntawm m-nitrotoluene hauv cov tshuaj methanol industrial kom tsim tau m-toluidine. Los ntawm kev kuaj xyuas ib qho thiab kev sim orthogonal, siv 80g m-nitrotoluene ua tus qauv xam thiab nyob rau hauv cov xwm txheej ruaj khov ntawm 200mL industrial methanol solvent, cov xwm txheej tshuaj tiv thaiv zoo tshaj plaws ntawm Chemicalbook yog: 2.0g catalyst, 6 teev lub sijhawm tshuaj tiv thaiv, thiab qhov kub ntawm cov tshuaj tiv thaiv Qhov kub yog 90 ℃, thiab qhov siab ntawm cov tshuaj tiv thaiv yog 1.6MPa. Cov ntsiab lus m-toluidine tau txais nyob rau hauv cov xwm txheej no yog 99.79%, cov ntsiab lus ntawm cov khoom sib xyaw yog 0.11%, thiab cov ntsiab lus ntawm cov khoom hnyav yog 0.10%
