PROCESS FOR THE PREPARATION OF COMPOUNDS HAVING -CH2-CHF- GROUPS

摘要

Compounds each having a -CH2-CHF- group and a number of carbon atoms of 4 or above are prepared by hydrogenating a compound having a -CCl=CF- group and a number of carbon atoms of 4 or above in the presence of a noble metal catalyst in a liquid or gas phase. The compound having a -CCl=CF- group and a number of carbon atoms of 4 or above is preferably a C4-C10 alicyclic one, and can be prepared by reacting a compound having a -CCl=CCl- group and a number of carbon atoms of 4 or above with a fluorinating agent.
