The high cellulose content in cassava peel has an opportunity to produce bio-based chemical productsin 5-hydroxymethylfurfural (5-HMF) form. This study aimed to determine the optimum conditions ofglucose dehydration reaction as a result of hydrolysis of the best cassava peel cellulose. The variablesobserved in this study were H2SO4 catalyst concentrations in the hydrolysis reaction, temperature andamount of deep eutectic solvents based on choline chloride/citric acid. The optimum dehydrationreaction conditions in this study was the glucose:deep eutectic solvents mass ratio of 1:6 at the reactiontemperature of 80 ºC. The highest yield of 64.50% at an initial glucose concentration of 5.70% usinga 1.5% H2SO4 catalyst during the hydrolysis of cassava peel cellulose. The results obtained in thisstudy indicated that addition of choline chloride/citric acid as deep eutectic solvent can increase theyield of 5-HMF.
