Thaum siv sodium nitrite rau kev tsim cov xim indigo hauv kev luam ntawv ncaj qha nrog naphthol AS dyes, kev tsim cov kua qaub sulfuric tsim cov kua qaub nitrous (HNO2).
Qhov no ua rau cov ntsev sodium ntawm naphthol AS ntawm daim ntaub poob ua xim liab-xim av, ua rau muaj keeb kwm yav dhau dawb. Txhawm rau tshem tawm cov kua qaub nitrous, feem ntau ntxiv 1-2 g / L ntawm oxalic acid rau hauv cov kua sulfuric acid, hloov lwm cov neeg sawv cev txo qis (piv txwv li, formic acid, urea, sulfur). Oxalic acid txo cov kua qaub nitrous mus rau hauv cov pa nitrogen, tiv thaiv HNO los ntawm kev hloov xim ntawm AS dyes.
Cov qauv sib xyaw ntawm oxalic acid thiab nitrous acid:
3H2C2O4 + 2HNO2 → 4H2 + 6CO2↑ + N2↑
