Abstract: Processes for preparing a polyamide, a polyamide material obtained by such processes, a nylon salt to be used therein, and processes for making the nylon salt are disclosed. The processes for preparing the polyamide include a direct solid state polymerization process. The salt used herein is a granulate material, prepared by a process, comprising spraying an aqueous solution comprising a diamine and a dicarboxylic acid dissolved in an aqueous medium, or an aqueous slurry comprising a diammonium dicarboxylate salt dispersed in an aqueous medium directly obtained from such an aqueous solution, onto or in a fluidized bed of diammonium dicarboxylate salt particles, while evaporating the aqueous medium, thereby forming a granulate salt material.

Abstract: The invention relates to a method for making a tablet having a diameter, as determined by the longest enveloping circle, in the range of 1 to 5 mm and/or a weight in the range of 1 to 100 mg—comprising an active ingredient selected from the group of pharmaceutical substances and active substances for a dietary supplement or nutraceutical, comprising (a) providing a lactose agglomerate comprising lactose, and a sugar alcohol; (b) providing the active ingredient; (c) mixing the agglomerate and the active ingredient, thereby obtaining a mixture; and (d) forming the tablet by direct compression.

Abstract: The present invention relates to a process for preparing a granular nylon salt material, wherein an aqueous mixture, comprising at least 65 wt. % of salt components, and at most 35 wt. % of an aqueous medium, the weight percentages (wt. %) being relative to the total weight of the aqueous mixture, is flashed from a pressure vessel via a flash valve into a flash chamber, thereby evaporating the aqueous medium in an amount sufficient to result in a residual moisture content of at most 7.5 wt. %, and forming a granular nylon salt material. The invention also relates to a process for preparing a nylon polymer, comprising direct solid state polymerization of the granular salt material prepared by flash granulation.
