This invention related to method of producing 5-ydroxymethyl furfural from fructose by using heterogeneous solid acid catalyst ICaT-2 without giving any considerable byproduct. This process is very economical as it involved high yield and simple separation process for product. Reactions are carried out by using the mixture of solvent system in batch reactor. The process is tolerance towards high fructose loading. The simplification in work-up, separation of product and very good recyclability of the catalyst make the process cost-effective, sustainable and efficient for industrial utilization. Isolation procedure for 5-hydroxymethyl furfural is also discussed. ICaT-2 is prepared by a co-condensation sol-gel route. Hexadecyl amine was dissolved in ethanol and water mixture. Mixture of tetraethyl orthosilicate and 3- (mercaptopropyl)trimethoxysilane were added to the above solution. It is treated with lanthanum chloride (400 mg) for 2 h. The slurry was filtered and treated with trifluromethanesulfonic acid (5.4 mmol) at 30 °C for 2 h. The slurry was filtered and washed with water and dried under vacuum to get the active ICaT-2 catalyst.
