Lignosulfonate solubility and pH value of the relationship

The use of spectrophotometry at 25 ℃ ligosulfonate at different pH medium solubility. The results show that the strong acid solution, its solubility is very small and almost constant, and in the neutral or alkaline medium, the concentration of the saturated solution 200g / L or so. Sodium lignosulphonate  from kraft …

Lignin production of carbon fiber is a trend

Goals for the future development of carbon fiber is applied so that more low-cost producers in the car . From the Federal University of Rio de Janeiro, Brazil (Federal University of Rio De Janeiro) professor Kawei Du (Calvado) states: If the United States uses 13 kg per car carbon fiber, …

The difference between lignin and lignosulfonate

Lignosulfonate is one of  lignin derivatives. It is the source and lignin, chemical structures and physical properties are different. Lignosulfonate mainly from the sulfite pulping process resulting “black liquor”, separated from the black liquor extracted, mainly  sodium lignosulphonate or calcium lignosulphonate. The three components of wood lignin itself (the other two …
