3-Methylaniline (m-toluidine) yog cov kua tsis muaj xim uas hloov xim daj lossis xim av xim av hauv huab cua lossis hauv qab ntawm lub teeb. Me ntsis soluble hauv dej, soluble hauv ethanol thiab ether. Nws tuaj yeem evaporate ua ke nrog dej vapor thiab tsim los ntawm kev txo cov tshuaj tiv thaiv ntawm m-nitrotoluene. 3-Methylaniline feem ntau yog siv los ua cov tshuaj synthesis nruab nrab.

Daim ntawv thov

Methylaniline yog ib qho yooj yim tshaj plaws aromatic amines thiab siv dav siv organic synthesis intermediate. Nws yog dav siv los ua organic synthesis intermediate rau dyes, tshuaj tua kab, tshuaj, thiab lwm yam. Chemicalbook. Tam sim no, kev tsim khoom hauv tsev tsuas yog siv nitrotoluene ua raw khoom, ethanol lossis methanol ua hnyav, thiab pob txha Ni ua cov tshuaj tiv thaiv hydrogenation los npaj methylaniline.

Cov txheej txheem synthesis siv nickel ua ib qho catalyst rau catalyze hydrogenation cov tshuaj tiv thaiv ntawm m-nitrotoluene hauv industrial methanol hnyav los tsim m-toluidine. Los ntawm ib qho kev kuaj xyuas thiab kev sim orthogonal, siv 80g m-nitrotoluene raws li kev ntsuas kev ntsuas thiab nyob rau hauv cov xwm txheej ruaj khov ntawm 200mL industrial methanol hnyav, qhov zoo tshaj plaws tshuaj lom neeg cov tshuaj tiv thaiv yog: 2.0g catalyst, 6h cov tshuaj tiv thaiv lub sij hawm, thiab cov tshuaj tiv thaiv kub kub yog 90. ℃, thiab cov tshuaj tiv thaiv siab yog 1.6MPa. Cov ntsiab lus m-toluidine tau txais nyob rau hauv cov xwm txheej no yog 99.79%, cov ntsiab lus ntawm lub teeb yog 0.11%, thiab cov ntsiab lus hnyav yog 0.10%.
