3-Methylaniline (m-toluidine) ndi madzi opanda mtundu omwe amasanduka achikasu kapena ofiira abulauni mumlengalenga kapena motsogozedwa ndi kuwala. Amasungunuka pang'ono m'madzi, amasungunuka mu ethanol ndi ether. Amatha kusungunuka pamodzi ndi nthunzi ya madzi ndipo amapangidwa ndi kuchepa kwa m-nitrotoluene. 3-Methylaniline imagwiritsidwa ntchito makamaka ngati mankhwala ophatikizika.

Mapulogalamu

Methylaniline ndi imodzi mwa amino acids osavuta komanso organic synthesis intermediate yomwe imagwiritsidwa ntchito kwambiri. Imagwiritsidwa ntchito kwambiri ngati organic synthesis intermediate ya utoto, mankhwala ophera tizilombo, mankhwala, ndi zina zotero. Chemicalbook. Pakadali pano, kupanga m'nyumba kumagwiritsa ntchito nitrotoluene ngati zopangira, ethanol kapena methanol ngati zosungunulira, ndi skeleton Ni ngati chothandizira kuchita hydrogenation reaction pokonzekera methylaniline.

Njira yopangira imagwiritsa ntchito nickel ngati chothandizira kuyambitsa hydrogenation reaction ya m-nitrotoluene mu industrial methanol solvent kuti ipange m-toluidine. Kudzera mu single factor examination ndi orthogonal experiments, pogwiritsa ntchito 80g m-nitrotoluene ngati benchmark yowerengera komanso pansi pa mikhalidwe yokhazikika ya 200mL industrial methanol solvent, mikhalidwe yabwino kwambiri ya Chemicalbook reaction inali: 2.0g catalyst, 6h reaction time, ndi reaction temperature. Kutentha ndi 90℃, ndipo reaction pressure ndi 1.6MPa. M-toluidine yomwe yapezeka pansi pa mikhalidwe iyi ndi 99.79%, kuwala kwa gawo ndi 0.11%, ndipo kulemera kwa gawo ndi 0.10%.
