| 20110257346 | Polyester Ethers Derived From Asymmetrical Monomers Based Upon Bisanydrohexitols - Asymmetrically substituted compounds of bisanhydrohexitols are described, including the bisanhydrohexitol isosorbide. The compounds are useful as monomers. The synthesis of polymers from the monomers is also described. | 10-20-2011 |
| 20110252503 | Plants With Improved Nitrogen Utilization and Stress Tolerance - The present invention relates to transgenic plants that have increased nitrogen use efficiency, stress tolerance, and/or alleviating a limitation such that yield is increased, or a combination of these and that have been transformed using a novel vector construct including a synthetic N-acetyl glutamate kinase (NAGK) gene that modulates nitrogen use in plants. The invention also includes the overexpression and enzymatic characterization of an arginine-insensitive NAGK isolated from a bacterial strain that improves stress tolerance and nitrogen uptake, metabolism or both. In various embodiments, the vector construct includes one or more nucleic acid sequences including SEQ ID NO: 1. The invention also relates to isolated vectors for transforming plants and to antibodies used for detecting transformed plants. The invention also relates to methods of expressing in plants the nucleic acid molecules corresponding to the nucleic acid sequences that modulate nitrogen use in plants or are modulated by nitrogen conditions. | 10-13-2011 |
| 20110237757 | Polyesters From Assymetrical Monomers Based Upon Bisanhydrohexitols - Asymmetrically substituted compounds of bisanhydrohexitols are described, including the bisanhydrohexitol isosorbide. The compounds are useful as AB monomers. The synthesis of polymers from the monomers is also described. | 09-29-2011 |
| 20090259057 | Dianhydrosugar Production Process - An enhanced process for the production of a dianhydrosugar, such as isosorbide, from the corresponding sugar alcohol is described. The sugar alcohol is combined with an acid catalyst and reacted at elevated temperatures and at atmospheric pressure, eliminating the need for a vacuum. High selectivity and yields are achieved. | 10-15-2009 |
| 20090259056 | Recovery and Refining of Dianhydrosugars - A process for the production of a refined dianhydrosugar-containing product is disclosed. The process includes controlled continuous crystallization of the dianhydrosugar-containing product to produce a solution saturated with the dianhydrosugar. The saturated solution is mechanically separated, for example by centrifugation, and the crystalline product is washed. The only solvent used is water. The dianhydrosugar-containing product is upgraded to at least 99.8% purity and recovery is 95% or greater. | 10-15-2009 |
