VERFAHREN ZUR HERSTELLUNG VON HYDROXIPIVALINSÄURENEOPENTYLGLYKOLESTER- GRANULATEN |
摘要 |
The production of neopentyl glycolhydroxypivalate (NPG-HP) granules (I) comprises pouring molten NPG-HP onto a cooling surface so that the melt solidifies, using a melt containing 3 wt.% NPG-HP crystals. Also claimed are: (i) NPG-HP granules (I) obtained by the above process, especially: (a) spherical granules with an average diameter of 3-16 mm; or (b) granules with an average diameter of 20-100 mm and at least two parallel faces 15-30 mm apart; and (ii) the use of a granulating system for the above process, with a precooler (2) for the NPG-HP melt, a precrystalliser (3), and a drop-forming system (4) or a flat spreader to bring the melt onto a cooling belt (6), with a crusher if a flat spreader is used. |
