Oxypropylation of lignins and characterization of the ensuing polyols

Four lignin samples (Alcell, Indulin AT, Curan 27-11P and Sarkanda) were converted into liquid polyols by a chain extension reaction with propylene oxide (oxypropylation). The reaction was carried out in a batch reactor using potassium hydroxide (KOH) as a catalyst. The oxypropylation process was fi...
