Outline of Final Research Achievements

To make hydrolysis of cellulose and production of 5-hydroxymethylfurfural (HMF) in a highly concentrated aqueous solution of lithium bromide which dissolves cellulose, various catalysts including a Bronsted acid, a solid acid/ base catalyst, a photocatalyst, a combined catalyst in which Lewis acid and a surfactant is combined, were tested. Among them, the highest HMF yield of 33.7% was obtained when a catalyst system in which a Lewis acid (SnCl2) and sodium dodecylsulfate was combined was added to a pressure-resistant test tube following the hydrolysis of cellulose and the neutralization with Bronsted acid. At this time, the selectivity of HMF was 33.7%, and the rate of residual solid was 21.8%.
