摘要:This invention provides a procedure for growing oligomers via a stepwise process. The oligomers can include porphyrins, which have been previously shown to be attractive candidates for molecular-based information storage. The stepwise synthesis procedure requires no protecting groups, thus eliminating protection/deprotection reactions that add complexity to the process.

摘要:A process for preparing cycloaliphatic amines by hydrogenating the corresponding aromatic compounds with hydrogen-comprising gas at a temperature of from 30 to 280° C. and a pressure of 50-350 bar, in the presence of ruthenium catalysts. The hydrogenation is performed in the presence of from 1% by weight to 500% by weight, based on the catalyst calculated as elemental ruthenium (Ru), of suspended inorganic additives, and to the use of the cycloaliphatic amines as a synthesis unit.

摘要:Synthesis and use of a new class of polymeric materials with favorable separation characteristics for the dehydration of ethanol and other organic solvents is described herein. The thermally rearranged (TR) polybenzoxazole (PBO), polybenzimidazole (PBI) and polybenzothiazole (PBT) membranes of the present invention can be used for the dehydration of ethanol during processing to fuel grade biodiesel by either pervaporation or vapor permeation. The unique microstructure of the membranes provides excellent separation characteristics, and this, coupled with their inherent thermal and chemical stability, enables their usage in other separations, such as the dehydration of other organic solvents.
