process for the production of 1,1,1,3,3,3 - hexafluorpropan 2 oil by catalytic hydrogenation of hexafluoracetonhydrat in the vapour phase

摘要

1,1,1,3,3,3 - hexafluorpropan 2 oil with high yield and high selectivity by hydrogenolyse in the vapour phase of a hydrats of hexafluoraceton by using either a nickelkatalysators or a palladiumkatalysators or both.hydrate of hexafluoracetons are easy to handle and to store it at room temperature, liquid or solid, and can also be refined to high purity, so that the catalyst has a long life, without being poisoned. the hydrogenolysereaktion takes place at relatively low temperatures, such as 40 to 200 degrees c, at atmospheric pressure.
