● Siv2,7-Tsis Tsim Nyog Ntsig ntsev yog ib qho kev tshawb xyuas ib qho kev xaiv kom txhaj tshuaj kom zoo sab nrauv cov chromatographic.
2,7-naphthhalenedisulfonic samo ntsev yog ib qho tshuaj lom neeg muaj kuab lom nrog cov mis molecular mis nyuj C10H6NA2o6S2. Nws yog ntsev tsis txog ntawm 2,7-naphthhalenedisulored acid, uas txhais tau tias nws muaj ob qho kev sib xyaw ua ke yog ib txwm pom muaj cov hmoov dawb lossis tawv-dawb thiab yog cov dej-viav-soluble. Nws yog ib qho siv tau siv cov kev zas xim nruab nrab hauv kev tsim cov reactive dyes, kua qaub ua kua qaub, thiab dyes ncaj. Cov qauv tsis sib xws rau cov solubility thiab ruaj khov ntawm cov khoom siv dej. Nws cov sulfonic acid pawg ua rau nws acidic heev, uas tuaj yeem siv nyob rau hauv cov ntawv thov uas yog qhov tseem ceeb rau kev coj ua tsis zoo li ntawm kev saib xyuas cov ntsev nrog kev saib xyuas thiab ua tib zoo saib xyuas kev nyab xeeb. Nws raug nquahu kom tshab xyuas cov ntaub ntawv cov ntaub ntawv kev nyab xeeb (MSDS) thiab ua raws li txhua cov lus qhia kev nyab xeeb thaum ua haujlwm nrog cov compound no.
