Process for removing olefinic impurities from fluorinated C3-C6-hydrocarbons The invention relates to a process for removing olefinic impurities from fluorinated C3-C6-hydrocarbons, with the exception of 1,1,1,2,3,3,3-heptafluoropropane (R 227), by bringing the contaminated fluorinated C3-C6-hydrocarbons into contact with an alcohol and a base and, simultaneously or subsequently, distilling off the fluorinated C3-C6-hydrocarbons.
