Abstract: Solid drug forms are produced by mixing and melting at least one pharmacologically acceptable polymeric binder and at least one pharmaceutical active ingredient, with or without conventional pharmaceutical additives, in the absence of a solvent to give a plastic mixture and shaping the mixture to the required drug form by extrusion, where the shaping takes place in two steps, with the extrudate being broken into shaped articles in a first step, and these shaped articles being rounded off in a second step in the plastic state.

Abstract: In the course of a method for the structural analysis of a chemical compound by data signals measured with the chemical compound being compared with calculated data, a first data signal is generated for at least one first compound having a structure which is similar to the assumed structure and has the same first substructure, but a different substituent Sv (instead of the substituent Sa of the compound being studied) in the substitution position; a second data signal is generated which constitutes the difference between the data from a second Sv-substituted compound and an unsubstituted (third) compound; a third data signal is generated which constitutes the difference between the data from a fourth Sa-substituted compound and an unsubstituted compound; a fourth data signal is generated from the first three data signals, and the measured data signal and the fourth data signal are compared with one another.

Abstract: Neopentyl glycol hydroxypivalate (NGH) is isolated from a mixture containing NGH, lower- and higher-boiling products and inorganic salts and purified in a two-stage process, whereinin a first separation stage, the inorganic salts and part of the higher-boiling products are separated off in a wiped-film evaporator and a vapor stream consisting of NGH, lower- and higher-boiling products is discharged and fed to a heat exchanger and condensed therein,and, in a second separation stage, the resulting condensate is distilled in a rectification column from which NGH is taken off in a side stream and condensed. Further discharges of the rectification column containing lower-boiling products or higher-boiling products are separately taken off. The higher-boiling products which comprise residual NGH are partly or completely recycled to the lower region of the rectification column.
