The soluble lignin concentration in the filtrate was determined through UV-spectroscopy by measuring the absorbance at 205 nm, using the value of 110 L·g−1·cm−1 as the absorptivity. The concentration of monomeric sugars and acetic acid in the soluble fraction was determined via high-...
The catalytic glycerol valorization has gained attention [14], in particular, its oxidation, transesterification, esterification, and hydrolysis (Figure 2). Figure 2. Processes for conversion of glycerol into added-value chemicals according to the number of articles published on the subject in the ...
