Using Response Surface Method to Optimize Conversion Reaction Conditions of Sucrose Into 5-hydroxymethyl-2-fufuraldehyde by A Combination of Heat and HCl as A Catalyst

5-Hydroxymethyl-2-furfuraldehyde is one of intermediate products of caramel reaction and it has a variety of applications in industry. Based on primary results, response surface method is employed to optimize conversion reaction conditions of sucrose into 5-HMF by a combination of heat and HCl as a catalyst and the target function is 5-HMF yield. The optimized conditions of conversion reaction is T = 17.4 (min), C = 1.81 (M), and R = 6.6:1 (mL:g); with the optimized conditions conversion reaction yield reaches the maximal value of 56,229 ± 2,519%. This research has provided important information for further research of 5-HMF and approach to large scale production and industrial production of 5-HMF
