Abstract

In a process for the production of neopentyl glycol hydroxypivalate granules by depositing a neopentyl glycol hydroxypivalate melt on a chill surface, on which the melt solidifies, as a flat film, which, after solidification, is comminuted to give granules. The melt contains less than 3% by weight, based on the total amount of neopentyl glycol hydroxypivalate, of neopentyl glycol hydroxypivalate crystals.
