Abstract
Official abstract text for this publication.
Psicose is converted into 5-hydroxymethylfurfural or an alkyl ether thereof in a process for the catalyzed conversion of psicose, including the steps of: a. forming a feed including psicose and water or at least one alkanol or a mixture thereof and b. converting the psicose in the feed at a temperature in the range of 50 to 300 degrees Celsius in the presence of a catalyst.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for the catalysed conversion of psicose into 5-hydroxymethylfurfural or an alkyl ether thereof, comprising the steps of: a. forming a feed comprising psicose and water and at least one alkanol or a mixture thereof, wherein the at least one alkanol is selected from the group consisting of 2-hydroxymethyl-propanol and 1-butanol, and mixtures thereof; and b. converting the psicose in the feed at a temperature in the range of 50 to 300 degrees Celsius in the presence of an acid catalyst. 2. The process of claim 1 , wherein the feed comprises water and at least one alkanol, or a mixture thereof in a molar ratio versus the psicose that is greater than 1. 3. The process of claim 1 , wherein the feed comprises a co-solvent. 4. The process of claim 1 , wherein an amount of water and alkanol or a mixture thereof is used that is sufficient to dissolve the psicose. 5. The process of claim 1 , wherein the acid catalyst is selected from organic acids, inorganic acids, salts, Lewis acids, ion exchange resins, zeolites and combinations or mixtures thereof. 6. The process of claim 1 , wherein the acid catalyst is a heterogeneous catalyst. 7. The process of claim 1 , wherein the acid catalyst is added to the feed in an amount varying from 0.01 to 40 mol % drawn on the psicose. 8. The process of claim 1 , wherein the psicose is included in the feed in the form of an alkyl glycoside. 9. The process of claim 8 , wherein the alkyl glycoside is formed by reacting psicose in the at least one alkanol in the presence of a homogeneous catalyst. 10. The process of claim 8 , wherein the alkyl glycoside is formed by reacting psicose in the at least one alkanol in the presence of a heterogeneous catalyst. 11. The process of claim 1 , which is performed in a continuous flow process.
