PROCESS FOR PRODUCING A FREE-FLOWING AND STORAGE-STABLE SOLID COMPRISING ESSENTIALLY .ALPHA.-ALANINE-N,N-DIACETIC ACID AND/OR ONE OR MORE DERIVATIVES OF .ALPHA.-ALANINE-N,N-DIACETIC ACID

摘要

A process is proposed for producing a free-flowing and storage-stable solid comprising essentially .alpha.-alanine-N,N-diacetic acid and/or one or more derivatives of .alpha.-alanine-N,N-diacetic acid proceeding from a powder of .alpha.-alanine-N,N-diacetic acid and/or one or more derivatives of .alpha.-alanine-N,N-diacetic acid by a. compacting the powder of .alpha.-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.
