Fig. 7From: Effects of aromatic ring type on reactions subsequent to the β-O-4 bond cleavage of non-phenolic lignin model compounds under alkaline pulping conditionsTime courses of the changes in the yields of the identified reaction products, when each β-O-4-type lignin model compound was individually reacted. The white and black marks represent the data obtained from the first and second trials, respectively. Reaction products are not illustrated, when their yields were very low (< 1%)Back to article page
