Abstract

The solubility of lignin in aqueous NaOH solutions was studied in relation to the lignin molecular weight, temperature, liquid to solid ratio, and ionic strength. A new procedure for determining the content of phenolic hydroxyls in lignin was developed. A formula was suggested for calculating the lignin solubility in aqueous alkali solutions.
