Method for Producing Quaternary Hydroxyalkylammonium Granules

摘要

The present invention relates a method for producing quaternary hydroxyalkylammonium granules, which is characterized by spraying an aqueous solution or suspension comprising a) a quaternary hydroxyalkylammonium compound b) a carrier material and c) optionally binders and/or other additives into a fluidized-bed apparatus. The fluidized-bed consists of granules that have the same composition as the aqueous solution or suspension sprayed into the apparatus.
