| 20120022228 | PURIFICATION OF AMPHOTERIC PRODUCTS, OR OF PRODUCTS LIABLE TO BE CONVERTED INTO AMPHOTERIC PRODUCTS - A process for purifying at least one product from a substrate containing at least one product, includes subjecting the substrate to centrifugal partition chromatography in an ion exchange displacement mode to purify the at least one product from the substrate, the at least one product being an amphoteric product. | 01-26-2012 |
| 20110150727 | Micro-Reactor System Assembly - A micro-reactor system assembly comprises a stack of at least n process modules ( | 06-23-2011 |
| 20110004007 | PROCESS FOR THE PREPARATION OF N-MONOSUBSTITUTED beta-AMINO ALCOHOLS - A process is disclosed for the preparation of a compound of formula | 01-06-2011 |
| 20100298567 | NITRATION OF ACTIVATED AROMATICS IN MICROREACTORS - The invention relates to the nitration of aromatic or heteroaromatic compounds, wherein an activated aromatic or heteroaromatic compound and a nitration agent, optionally in the presence of a solvent, are mixed intensely in a microreactor, and wherein the proportion of the nitration agent to the activated aromatic or heteroaromatic compound, the concentration of nitration agent in the reaction mixture, and the temperature are selected at levels such high that the nitration begins autocatalytically, and wherein the nitration product is obtained after leaving the microreactor and, optionally after an after-reaction time outside the microreactor. | 11-25-2010 |
| 20100249370 | PROCESS FOR THE PRODUCTION OF PRAMLINTIDE - Pramlintide, a peptide having the 37 amino acid sequence KCNTATCATQRLANFLVHSSNNFGPILPPT-NVGSNTY-NH2 is prepared via a convergent three-fragment synthesis strategy from the fragments comprising the amino acid residues 1-12, 13-24 and 25-37, respectively. | 09-30-2010 |
