Taw qhia
2,6-Dinitrotoluene, tseem hu ua DNMT, yog cov organic compound. Nws yog xim tsis muaj xim, crystalline khoom uas yuav luag insoluble hauv dej ntawm chav tsev kub thiab soluble hauv cov kuab tshuaj organic xws li ether thiab roj av ether.
2,6-Dinitrotoluene feem ntau yog siv los ua cov khoom siv hauv cov khoom tawg thiab tawg. Nws muaj qhov ua tau zoo tawg thiab ruaj khov, thiab feem ntau siv rau hauv kev npaj cov khoom tawg rog thiab tub rog.
Txoj kev npaj 2,6-dinitrotoluene feem ntau tau los ntawm nitrification ntawm toluene. Txoj kev npaj tshwj xeeb suav nrog dropwise toluene hauv kev sib xyaw ntawm nitric acid thiab sulfuric acid, thiab cov tshuaj tiv thaiv yog nqa tawm hauv cov xwm txheej kub.
Nyob rau hauv cov nqe lus ntawm kev nyab xeeb, 2,6-dinitrotoluene yog ib yam khoom txaus ntshai. Nws yog khaus heev thiab carcinogenic, thiab tej zaum yuav ua rau khaus thiab ua xua yog tias nqus tau los yog kov ntawm daim tawv nqaij. Thaum ua haujlwm, yuav tsum tau ua nruj me ntsis ntsuas kev nyab xeeb, xws li hnav hnab looj tes tiv thaiv, tsom iav thiab lub tshuab ua pa, thiab ua haujlwm hauv qhov chaw muaj cua zoo. Kev khaws cia thiab tuav ntawm 2,6-dinitrotoluene kuj yuav tsum tau ua raws li cov kev cai thiab cov qauv tsim kom muaj kev nyab xeeb ntawm tus kheej thiab ib puag ncig kev nyab xeeb.
