Sodium Lignosulphonate ( lignosulfonate ) is a water reducer and is mainly used for concrete mixture as water-reducing additive. This chemical has low air content, water reducing rate is high, low dosage, adapt to most kind of cement.

Although sodium superoxide is the primary product (90 % theoretical), quantitative and qualitative evaluation of the side-products (using (1) H NMR, iodometric titration, and on-line mass spectrometry) shows the presence of sodium acetate (∼3.5 %), and th
