    摘要： R-α-Lipoic acid and its homologs are converted to their magnesium salts in the presence of a reduced form of the acid, dihydro-(+)-lipoic acid in the case of R-α-lipoic acid itself. The reduced form serves as a polymerization inhibitor, resulting in a Mg di-R-α-lipoate product of higher purity. The reduced acid retained in the product tends to convert to the starting acid, thereby avoiding the inclusion of an extraneous polymerization inhibitor in the product.

    摘要： Simulated moving bed (SMB) chromatography involving a series of columns serially connected in a circuit is performed in a modified protocol by dividing the columns into two groups isolated from flow communication with each other and using one of the two groups solely for extraction of the more strongly retained component from the solid phase while the other group is operated in the conventional SMB manner. The sites of introduction and withdrawal and the site of division between the two groups of columns are all rotated around the circuit as in conventional SMB chromatography, but the process is capable of separating component mixtures with non-linear isotherms and of extracting solutes that are very strongly retained on the solid phase.

    摘要： A method for releasing an anhydrous gas in a gas phase at a target rate includes the step of obtaining a vessel at least partially filled with the anhydrous gas. The anhydrous gas is at least partially in a liquid phase and the vessel has an outlet for releasing the anhydrous gas in the gas phase. The method further includes releasing at least a portion of the anhydrous gas from the vessel through the outlet in the gas phase; applying a heat transfer fluid having a temperature of 32° F. to 150° F. to an exterior surface of the vessel during the releasing step, such that the anhydrous gas in the liquid phase is evaporated and the anhydrous gas in the gas phase is released at the target rate; and measuring starting and end weights of the vessel to monitor the releasing of the anhydrous gas in the gas phase.

    摘要： A novel stereochemical mixture of 1,6-diaryl-2,5-diaminohexanes, such as a mixture of stereoisomers of 1,6-diphenylhexane-2,5-diamine, is described. Also described are methods of preparing stereochemically pure 1,6-diaryl-2,5-diaminohexanes, and particularly stereochemically pure 1,6-diphenyl-2,5-diaminohexane. Also described is the use of both the mixture of stereoisomers and the individual stereoisomers.
