    摘要: Method for the manufacture of 5-hydroxymethylfurfural derivatives by reacting a fructose and/or glucose-containing starting material with an alcohol in the presence of a catalytic or sub-stoichiometric amount of solid (“heterogeneous”) acid catalyst. The catalysts may be employed in a continuous flow fixed bed or catalytic distillation reactor. The ethers can be applied as a fuel or fuel additive.

    摘要: The invention provides a fuel composition comprising a ring-hydrogenated alkyl furfuryl ether of the general formula (I): (I) R″-TF-CH2-O—R wherein TF represents a 2,5-disubstituted tetrahydrofuran ring, wherein each R independently represents a hydrocarbyl group having from 1 to 20 carbon atoms and wherein each R″ independently represents a methyl group, a hydroxymethyl group, the product of an aldol condensation reaction or an alkoxymethyl group of the general formula (II): (II) —CH2-O—R′ wherein each R′ independently represents a hydrocarbyl group having from 1 to 20 carbon atoms. The invention also provides novel and useful ring-hydrogenated alkoxymethyltetrahydrofuran ethers of the general formula (I) above. Moreover, these ring-hydrogenated alkoxymethyltetrahydrofuran ethers disclosed herein have never been used as fuel component, and therefore the use of these ethers has also been claimed as an invention. A further embodiment of the current invention is the process for preparing these components. Finally, the use of a 5-(alkoxymethyl)furfural, and/or a 2,5-bis(alkoxymethyl)furan as hydrogen storage molecules, in particular for fuel purposes is claimed as a further embodiment of the current invention.
