| 21 | Method of synthesizing levorotatory p-hydroxyphenylglycine compounds | US13994085 | 2012-02-15 | US08940928B2 | 2015-01-27 | Jianzhong Xie; Xiubin Guo; Lixian Zhao; Chao Liu |
| The present invention relates to the field of chemical synthesis, particularly to a method of synthesizing levorotatory p-hydroxyphenylglycine compounds, which eliminates the subsequent processes of resolution, racemization processings, etc., simplifies operational steps; and acids with small organic molecule are chosen as catalyst in the second step, which not only is conducive to the realization of a industrialized production, but also makes the ee value of the end products be 88.1˜98.0% by determining the catalyst, the reaction solvent, the reactive substance, the reaction temperature, and the reaction duration; non-aqueous solvent is used in the second step, to avoid the discharging of phenol-containing waste water, thus environmental pollution is reduced. | ||||||
| 22 | Compositions and methods for making alpha-(1,2)-branched alpha-(1,6) oligodextrans | US12775656 | 2010-05-07 | US08816067B2 | 2014-08-26 | Thierry Naeye; Alexandra Einerhand; Michel Lopez; Susan M. Potter; Magali Remaud-Siméon; Pierre Frédéric Emmanuel Monsan |
| Compositions for improving the health of a subject comprise alpha-(1,2)-branched alpha-(1,6) oligodextrans, preferably with an average molecular weight between about 10 kDa and 70 kDa, between about 10% and 50% alpha-(1,2)-osidic side chains, and having at least partial indigestibility in the subject. Methods for improving the health of a subject comprise administering the composition to a subject in an amount effective to improve gut health, or to prevent or treat a gastrointestinal disorder, a cholesterol-related disorder, diabetes, or obesity. Methods for making oligodextrans having controlled size and controlled degree of branching comprise providing alpha-(1,6) oligodextrans having an average molecular weight between 0.5 and 100 kDa and introducing at least 10% alpha-(1,2)-osidic side chains onto the alpha-(1,6) oligodextrans. | ||||||
| 23 | Use of ultra-low sodium silica-aluminas in the alkylation of aromatics | US944571 | 1992-09-14 | US5302732A | 1994-04-12 | Karl Z. Steigleder; Christine M. Conway; David M. Baldwin; Diane C. Dierking |
| Silica-aluminas having a sodium content less than about 0.1 weight percent show increased stability when used as a catalyst for the alkylation of aromatic compounds. Where such silica-aluminas are used as the catalyst in detergent alkylation their increased stability permits continuous alkylation to be performed at lower temperatures, as a result of which the detergent alkylate product shows an incrementally higher linearity. Fluorided silica-aluminas having a sodium content of under 0.05 weight percent are particularly advantageous. | ||||||
