WebAbstract. The catalytic hydrogenolysis of softwood lignins is normally conducted at temperatures below 200 °C but tends to provide monomer yields of less than 30 mol% as a consequence of the non-cleavable 4-O-5 and condensed (C–C) linkages of phenylpropane units in lignin.In the present study, catalytic hydrogenolysis at higher temperatures … WebBacterial polyester poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and alkaline lignin composites were prepared via melt processing method, and the influence of amorphous lignin on the crystallization behavior and thermal properties of PHBV were investigated. It was found that dual melting peaks appeared in DSC curves of PHBV/lignin composites, … ctrl+shift o que faz
