Abstract

5-Hydroxymethyl-2-furfural is produced by heating an aqueous solution of a keto-hexose sugar at a temperature between 125 DEG and 225 DEG C. in the presence of an unsubstituted saturated aliphatic monohydric alcohol, preferably having from 1 to 5 carbon atoms in the molecule, the molar ratio of the alcohol to water in the solution being between 0.1 and 0.4. Preferably a catalyst is used. An acidic catalyst, i.e. an inorganic or organic acid or a substance which generates an inorganic or organic acid radical is used, e.g. hydrochloric acid, hydrobromic acid, phosphoric acid, zinc chloride and aluminium chloride. The preferred catalysts are strong mineral acids, especially sulphuric acid. In some cases it may be desirable to stop the reaction before the maximum yield of 5-hydroxy methyl-2-furfural is obtained. In the examples: (a) levulose, dilute sulphuric acid and n-butyl alcohol are heated together at 170 DEG C.; (b) sucrose, dilute sulphuric acid and n-butyl alcohol are heated together at 150 DEG C. in two stages; (c) crude black-strap molasses is diluted with water and de-ashed by passage over a column of cation exchange resin; this solution is mixed with butanol and heated at 150 DEG C.; and (d) various mixtures of sucrose, sulphuric acid, n-butyl alcohol and water are heated at 150 DEG C. In all cases 5-hydroxymethyl-2-furfural is obtained. Another material which may be used as starting material is inulin from Jerusalem artichoke tubers or chicory. When sucrose is used as starting material it is rapidly hydrolysed to invert sugar. Specifications 591,858, [Group IV], 600,871 and U.S.A. Specification 2,498,918 are referred to.
