Summary

The nature of the product depends upon (i) the nature of the hydrolysinand condensing agents and (ii) the concentrations of the reagents used therein. [...] Philips and Weihe reported the formation of lignin-furfural condensate by the interaction of the two in presence of hydrochloric acid "2 A. P. GUPTA AND B. C. GUHA Meigs9 patented a process showing that in the formation of resins by the interaction between phenol and dextrose the phenol might be substituted by farfural Hence it is quite evident that there is every Ogsibility of the formation of [...] With the rise of time above 4 hours most probably there is some tendency for deterioration in the quality of the resin as indicated by the slight lowering of the solubility in acetone due to a portion of the resin undegoing setting by excessive heat treatment or due to some local charring actions caused by the very high consistency of the product Influence of pressure of reaction.—In this s [...] The results of these experiments are shown in Table II From Table II it is quite evident that the quality of the product improves the solubility in acetone as also the total amount of resin fronied increase with increase in the pressure of digestion. [...] After the reaction was over the nature of the product was noted and the percentage of solubility of the product in acetone determined as usual.
