Very little research has been done to explore commercial application of the thermochemical degradation of polysaccharide materials to organic acids in alkaline solution. Much of the work on alkaline degradation of polysaccharides has been conducted at 100C or lower to investigate mechanisms of degradation, reaction termination and the effects of molecular structure. However, little conversion of polysaccaharides to acids occurs at these low temperatures. Most investigations at higher temperatures have involved study of the alkaline pulping process at approximately 170C, where polysaccharide degradation is limited and not desired.
