Abstract

A process for the production of tablet-shaped granular material from a melt, in which(i) a melt is prepared,(ii) the prepared melt is shaped to droplets,(iii) the droplets are deposited on a cooling surface, and(iv) the deposited droplets solidify to give the granular material, wherein the melt comprises an alcohol, and the melt has a melting point of 30° C. or above.
