Cov tshuaj nruab nrab: Hauv kev lag luam tshuaj, p-toluidine yog ib qho nruab nrab ntawm cov tshuaj pyrimethamine, thiab kuj tseem siv rau hauv kev npaj cov tshuaj tua kab xws li pyrimethamine thiab lwm yam khoom.
Lwm yam kev siv: p-Toluidine kuj tseem siv tau ua cov tshuaj reagent thiab kuj tseem siv tau rau hauv kev tsim cov organic. Hauv kev tshuaj lom neeg, ntxiv rau kev ua cov kuab tshuaj, nws kuj tseem siv tau ua cov kua impregnating rau cov ntsuas refractive ntawm cov zaub mov.
Hauv kev xaus, p-toluidine muaj txiaj ntsig dav dav hauv cov xim pleev, tshuaj thiab lwm yam tshuaj synthesis.

p-Toluidine ua lub luag haujlwm tseem ceeb ua ib qho tshuaj nruab nrab. Cov lus piav qhia ntxaws ntxaws hauv qab no:

Cov xim zas thiab tshuaj intermediates: p-Toluidine feem ntau yog siv ua cov xim zas nruab nrab thiab cov tshuaj intermediate rau cov tshuaj pyrimethamine, thiab ua lub luag haujlwm tseem ceeb hauv kev lag luam xim zas thiab kev tsim tshuaj.

Kev tsim ntau yam tshuaj: Nws cov khoom siv, xws li N, N-dimethyl-p-toluidine thiab N, N-dihydroxyethyl-p-toluidine, muaj cov haujlwm pharmacological muaj zog thiab tuaj yeem siv los tsim cov tshuaj tua kab mob, tshuaj tiv thaiv kab mob qog noj ntshav, thiab lwm yam tshuaj.

Daim ntawv thov dav: p-Toluidine thiab nws cov derivatives yog siv ua intermediates hauv kev tsim tshuaj thiab muaj ntau yam kev cia siab rau daim ntawv thov, tsis yog tsuas yog txwv rau cov tshuaj ib txwm muaj, tab sis kuj suav nrog kev tsim tshuaj ntau dua thiab kev tsim cov khoom siv polymer.

Hauv kev xaus, p-toluidine, ua ib qho tshuaj nruab nrab, muaj txoj haujlwm tseem ceeb thiab muaj txiaj ntsig dav hauv kev lag luam tshuaj.
