4 aminobenzenesulfonic acid refractive index. Academiaedu is a platform for academics to share research papers. Handbook of Chemistry and Physics 84th - David R Lide. The treatment of cotton fabrics with 4-aminobenzenesulfonic acid-chloro-triazine adduct increased the anionic sites on the fabric surface and facilitated the exhaustion of QACs Son et al 2006.
In the study the exhaustion was affected by pH concentration temperature and exhaustion time. For polyester fibres which contain carboxylic or sulfonate groups QAC can be directly exhausted.
