O-toluidine yog ib qho organic compound uas muaj ntau yam kev siv. Cov hauv qab no yog nws cov kev siv tseem ceeb:

Kev lag luam zas xim: siv los npaj cov xim azo, cov xim triphenylmethane, thiab lwm yam, thiab tseem yog cov xim nruab nrab, nws ua lub luag haujlwm tseem ceeb hauv kev tsim cov xim sib txawv xws li GBC liab thiab G liab.
Kev lag luam tshuaj: siv los npaj cov tshuaj xws li o-cloxacillin, methaqualone, bisoprolol thiab rhodin.
Kev lag luam tshuaj tua kab: siv los ua cov tshuaj tua kab xws li chlordimeform.
Lwm yam kev siv: kuj siv ua cov roj hmab vulcanization accelerator, xim ziab tus neeg sawv cev, thiab saccharin hluavtaws, thiab lwm yam.
Hauv kev xaus, o-toluidine yog siv dav hauv cov xim pleev xim, tshuaj, tshuaj tua kab thiab lwm yam tshuaj lom neeg, thiab yog cov khoom siv tseem ceeb ntawm cov organic synthesis.

Cov txheej txheem npaj ntawm o-toluidine feem ntau suav nrog cov hauv qab no:

Txoj kev txo qis Hydrogenation: o-nitrotoluene thiab hydrogen raug ntxiv rau hauv lub reactor, thiab qhov kev txo qis raug ua tiav ntawm qhov kub thiab siab kom tsim tau o-toluidine.
Txoj kev txo cov hmoov hlau: o-nitrotoluene raug txo nrog cov hmoov hlau hauv cov kua qaub dilute, thiab tom qab ntawd cov o-toluidine nyoos raug sib cais, thiab tom qab ntawd cov khoom ntshiab tau txais los ntawm kev yaj cov kua qaub, alkali precipitation thiab lwm yam kauj ruam.
Txoj kev amination ncaj qha: o-nitrotoluene raug tshuaj xyuas ncaj qha nrog ammonia nyob rau hauv qhov kev ua ntawm cov tshuaj catalyst los tsim o-toluidine, tab sis cov khoom purity qis.
Cov txheej txheem no muaj lawv tus kheej cov yam ntxwv thiab tsim nyog rau ntau yam kev xav tau ntawm kev tsim khoom. Hauv kev siv tiag tiag, txoj kev npaj tsim nyog tuaj yeem xaiv tau raws li qhov xwm txheej tshwj xeeb.
