Chemical Properties:Lub teeb daj flammable kua, uas tig liab xim av thaum raug huab cua thiab tshav ntuj. Me ntsis soluble hauv dej, soluble hauv ethanol thiab ether.

Lub hom phiaj:
1) Siv ua intermediates rau dyes, tshuaj tua kab, tshuaj thiab organic synthesis
2) Siv los ua kev tshuaj ntsuam xyuas cov tshuaj thiab cov tshuaj zas xim, thiab tseem siv rau hauv cov organic synthesis
3) Ortho-toluidine yog nruab nrab ntawm cov fungicides tricyclazole, metalaxyl, furoxaline, insecticides thiab acaricides dimethamidine, lilacan, herbicides ibutachlor, napachlor, acetochlor, thiab lwm yam. Nws kuj yog lub ntsiab nruab nrab ntawm cov dye Chemicalbook. Nws tuaj yeem tsim maroon puag GBC, loj liab puag G, liab puag RL, naphthol As-D, kua qaub liab 3B, yooj yim fuchsin, thiab lwm yam., thiab tuaj yeem tsim cov dyes reactive.
4) Nws yog siv los tsim cov khoom lag luam xws li maroon puag GBC, loj liab puag G, liab puag RL, naphthol ASD, kua qaub liab 3B, yooj yim fuchsin thiab yooj yim liab T, nrog rau cov tshuaj tua kab tua kab, saccharin, vulcanization nce tus neeg saib xyuas, beneficiation agent toluene arsenic acid, thiab lwm yam.

Txoj kev tsim khoom:

1) tau los ntawm kev txo cov o-nitrotoluene. Kev txo cov tshuaj tiv thaiv tuaj yeem siv cov hmoov hlau ua cov tshuaj txo qis, thiab tseem tuaj yeem ua hydrogenated nyob rau hauv lub xub ntiag ntawm tooj liab catalyst ntawm 260-280 ° C kom tau o-methyl Chemicalbook aniline. Cov ntsiab lus ntawm o-toluidine hauv cov khoom lag luam (tag nrho cov ntsiab lus amino) yog siab dua 99%, thiab txoj kev txo hydrogenation siv 1,300 kg ntawm o-nitrotoluene thiab 940 m3 ntawm hydrogen ib tuj ntawm cov khoom.

2) Txoj kev npaj yog npaj los ntawm catalytic hydrogenation txo ntawm o-nitrotoluene. Vim qhov sib txawv hydrogenation catalysts, cov tshuaj tiv thaiv kab mob sib txawv. Piv txwv li, tooj liab catalyst yog siv, thiab cov tshuaj tiv thaiv kub yog 260 ° C. Nickel catalysts kuj tseem siv tau.
