Solvolysis lignin

Solvolysis lignin prepared with 2,2-dimethoxypropane (24). c Wood meal singly labeled with 14C was employed. This estimation was made on the basis of radioactivity and UV absorbance (25). [Pg.155]

This paper, then, describes the preparation and characterization of a solvolysis lignin prepared under conditions that are very different to previous solvolytic lignin preparations. In particular, no water, acid or base is used in this process during the delignification step. The lignin is then acid precipitated and hydrolyzed in dilute aqueous solution to produce monomeric substituted phenols. [Pg.236]

In the present study, PU s containing lignin were investigated with reference to thermal stability, which is one of the basic thermal properties of polymers. Thermal degradation of PU s which were obtained from solvolysis lignin was studied using thermogravimetry (TG). The inflammability of... [Pg.384]
