VERFAHREN ZUR HERSTELLUNG VON HYDROXYMETHYLCYCLOPROPAN (CYCLOPROPYLMETHANOL)

摘要

For the selective production of hydroxymethylcyclopropane, cyclopropanecarboxylic acid esters are hydrogenated in the presence of a Zn chromite catalyst in the sump phase or trickling phase under a hydrogen pressure of 200-320 bar and at temperatures of 200 DEG -350 DEG C. Preferably, cyclopropanecarboxylic acid esters are used, the alcohol component of which contains 1-10, especially 1-8 carbon atoms.
