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., (b) withdrawing powder or granules, respectively, from the spray-dryer or spray-granulator, respectively, (c) separating off fmes from said powder or granules, wherein said fmes have a maximum particle diameter of 350 (d) separating off lumps from said powder or granules, wherein said lumps have a particle diameter of 1,500 m or more, (e) milling said lumps to a maximum particle diameter of 500 m, (f) re-introducing said fmes from step (c) and milled lumps from step (e) into the spray-dryer or spray-granulator, wherein the share of fines is in the range of from 0.5 to 20% by weight of the total chelating agent (A) withdrawn in step (b) and the share of milled lumps is in the range of from 5 to 60% by weight of the total chelating agent (A) withdrawn in step (b).

Process for making a solid alkali metal salt (A) of an aminocarboxylate complexing agent, said process comprising the steps of (a) providing a 40 to 80% by weight aqueous solution or slurry comprising salt (A), (b) optionally, heating said slurry or solution to a temperature in the range of from 50 to 150? C., (c) introducing the slurry or solution from step (a) or, if applicable, step (b) into an essentially horizontal cylindrical drying apparatus containing a stirring element that rotates around an essentially horizontal axis and that is charged with solid particles of salt (A), and (d) removing most of the water by evaporation, (e) removing solid salt (A) as granule.

Methods of making polyamides from renewable materials, such as natural oils, are generally disclosed herein. In some embodiments, the polyamides are nylon-10. In some such embodiments, nylon-10 is made by polymerizing 10-aminodecanoic acid, or esters thereof. In some further such embodiments, the 10-aminodecanoic acid monomers (or esters thereof) are derived from natural oils via the metathesis of unsaturated fatty acid moieties of the natural oil.

A problem to be solved by the present invention is to provide an acylcarnitine composition easy to handle in a solution state and having long-term storage stability. The problem is solved by an acylcarnitine composition characterized by having at least one or more acylcarnitines dissolved in an organic solvent containing an organic acid.
