However, a comprehensive study on the A in the presence of B has not yet been clearly established, which is probably due to the condensation reaction occurred that concurrently among the A components themselves during liquefaction. This could be lie in the reaction that the hydroxyl group of glycerol reacts with lignin can hinder the free-radical fragment, because of that retarded re-condensation of the fragments and increasing the liquefaction yield This is because high acid concentration enhances the re-condensation reactions for the liquefied fragments resulting in an increase in the amount of insoluble residue (re-polymerization) after liquefaction ¿´Ó¢Îı¾Éí£¬Ó﷨ʲôµÄÓÐ벡Â𣿠[ Last edited by hairongz on 2010-6-8 at 21:59 ] |
