Process for producing a free-flowing, storage-stable solid, and use of a free-flowing, storage-stable solid.

摘要

A process is proposed for producing a free-flowing and storage-stable solid comprising essentially -alanine-N,N-diacetic acid and/or one or more derivatives of -alanine-N,N-diacetic acid proceeding from a powder of -alanine-N,N-diacetic acid and/or one or more derivatives of -alanine-N,N-diacetic acid by a. compacting the powder of -alanine-N,N-diacetic acid on a roller press to obtain slugs, b. crushing the slugs and c. screening the crushed slugs, which comprises performing the compaction on the roller press with addition of polyethylene glycol with a melting point greater than 35° C.
