| 20110282020 | PROCESS FOR PREPARING A POLYMER HAVING A 2,5-FURANDICARBOXYLATE MOIETY WITHIN THE POLYMER BACKBONE AND SUCH (CO)POLYMERS - A process for preparing a polymer having a 2,5-furandicarboxylate moiety within the polymer backbone and having a number average molecular weight of at least 10,000 (as determined by GPC based on polystyrene standards) includes a first step where a prepolymer is made having the 2,5-furandicarboxylate moiety within the polymer backbone, followed in a second step by a polycondensation reaction. In the first step a 2,5-furandicarboxylate ester is transesterified with a compound or mixture of compounds containing two or more hydroxyl groups, in the presence of a tin(IV) based transesterification catalyst. In the second step at reduced pressure and under melt conditions the prepolymer prepared in the first step is polycondensed in the presence of a tin (II) based polycondensation catalyst until the polymer is obtained. This polymer may then be subjected to Solid State Polycondensation. Polymers so produced may have a 2,5-furandicarboxylate moiety within the polymer backbone, and having a number average molecular weight of at least 20,000 (as determined by GPC based on styrene standards), and an absorbance as a 5 mg/mL solution in a dichloromethane:hexafluoroisopropanol 8:2 at 400 nm of below 0.05. | 11-17-2011 |
| 20110107659 | FUEL COMPOSITION - 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. | 05-12-2011 |
