摘要:
The present invention concerns the use of a furan ether as fuel or fuel additive and a fuel composition comprising a furan ether, wherein the furan ether has been selected from 2-alkoxymethylfuran, 5-(tertbutoxymethyl)-2-(methoxymethyl)furan, 5-(tertbutoxymethyl)-2-(ethoxymethyl)furan, 5-(2-butoxymethyl)-2-(methoxymethyl)furan and the ether produced by the method of reacting a starting material comprising at least one 5-substituted furfural and optionally comprising furfural with hydrogen in the presence of an alcohol and a catalyst system.
摘要:
The invention provides a fuel component, based on or comprising a ring-hydrogenated alkyl furfuryl ether of the general formula (I): €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ (I)€ƒ€ƒ€ƒ€ƒ€ƒR"-TF-CH2-O-R wherein TF represents a 2,5-substituted tetrahydrofuran ring, wherein each R independently represents an alkyl group having from 1 to 20 carbon atoms and wherein each R" independently represents a hydrogen atom, a methyl group, a hydroxymethyl group, the product of an aldol condensation reaction or an alkoxymethyl group of the general formula (II): €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ (II)€ƒ€ƒ€ƒ€ƒ€ƒ-CH2-O-R' wherein each R' independently represents an alkyl group having from 1 to 20 carbon atoms. The invention also provides novel and useful ring-hydrogenated alkoxymethyltetrahydrofuran ethers such as 2-(alkoxymethyl)tetrahydrofuran, 5-methyl-2-(alkoxymethyl)tetrahydrofuran, 5-hydroxymethyl-2-(alkoxymethyl)tetrahydrofuran and 2,5-bis(alkoxymethyl)tetrahydrofuran 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, 2-alkoxymethylfuran 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.
摘要:
Method for the manufacture of 5-alkoxymethyl furfural derivatives by reacting a fructose and/or glucose-containing starting material with an alcohol in the presence of a catalytic or sub-stoechiometric amount of 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.
