    Kev piav qhia

    Lub disodium ntsev thiab caustic soda concentrated tov ntawm Koch acid (1-naphthylamine-3 mine6 thiab 8-trisulfonic acid) tau rhuab thiab melted nyob rau hauv lub siab kub ntawm txog 180-190 ℃, ces cov melts yog yaj nyob rau hauv dej thiab ces acidified thiab nag xob nag cua.Me ntsis soluble hauv dej txias, soluble hauv alkaline daws xws li dej qab zib tshauv thiab caustic soda.

    Nrog ferric chloride tov yog xim av liab.Cov kua qaub ntsev muaj xim liab fluorescence, thiab dhau los ua ntshav liab tom qab ntxiv alkali.H acid cov khoom feem ntau yog muab tshuaj txhuam los yog hmoov.
