Abstract: Process for making a powder or granule containing at least one chelating agent selected from alkali metal salts of methyl glycine diacetic acid (MGDA) and glutamic acid diacetate (GLDA) and iminodisuccinic acid (IDS), said process comprising the steps of (a) introducing an aqueous solution or aqueous slurry of the respective chelating agent (A) into a spray-dryer or spray-granulator, and removing most of said water by spray-drying or spray granulation using a gas with an inlet temperature of 125 to 250° C.

Abstract: The invention relates to a process for preparing silica-coated particles of an inorganic expanding agent, the silica-coated particles and their use. The silica-coated particles show a delayed release of the expanding agent particularly in alkaline medium and at elevated temperatures. They are therefore useful in the oil and construction industry.

Abstract: Process for manufacturing granules of at least one alkali metal salt of aminopolycarboxylic acid (A), comprising the steps of (a) providing an aqueous slurry of alkali metal salt of aminopolycarboxylic acid (A), (b) maintaining said aqueous slurry at a temperature in the range of from 50 to 90° C. over a period of time in the range of from 2 to 180 hours, (c) spray granulating said slurry with a gas inlet temperature of at least 150° C.

Abstract: The present invention relates to a process for drying particulate polymers, comprising the steps of: a) providing a particulate polymer comprising from 60 wt % to 90 wt % of at least one solvent based on the total weight of particulate polymer and solvent, b) mechanically predrying the particulate polymer to a content of the at least one solvent of from 20 wt % to 50 wt % based on the total weight of particulate polymer and solvent, wherein the mechanical predrying in step b) is carried out with a roller press, and c) end-drying the particulate polymer to a content of the at least one solvent of from 0 wt % to 15 wt % based on the total weight of particulate polymer and solvent, wherein the particulate polymer is a polymer comprising repeating units of formulae I, II and/or III The present invention further relates to a process for working up particulate polymers.

Abstract: Pharmaceutical coatings obtained from coating compositions based on film-forming copolymers of N,N-diethylaminoethyl methacrylate (DEAEMA) and methyl methacrylate (MMA) comprising a weight ratio of DEAEMA:MMA in the range of 35:65 to 55:45, where the copolymers are present partially neutralized with C3-C10-dicarboxylic acids.

Abstract: Described is a storage-stable dust-free homogeneous particulate formulation. The formulation consists of (a) at least one water-soluble Vitamin E-derivative, (b) at least one hydrophilic polymer, (c) optionally additional surface-active substances, and (d) optionally additional pharmaceutical additives. The sum of (a), (b), (c) and (d) equals 100% by weight of the formulation. The fines fraction with particle diameters of less than 100 ?m is less than 10% by weight. Describe also is a process for manufacturing the formulation, and use of the formulation as a solubilizing composition in pharmaceutical formulations.
