Particle-Size Distribution of Wood Resin and Sulfate Lignin in Aqueous Alkaline Solution

“…We found that the systems are heterogeneous, containing mainly nanoparticles, and tend to aggregate with changing temperature. We also proved formation of coagulation compounds in solutions containing sulfate lignin and wood resin [3]. These compounds are unstable not only at temperature changes but also in the presence of electrolytes [4].…”
