Abstract: Procedure for the flotation of silvina from crude potassium salts, characterized in that diamines of the formula are used as collectors ** (see formula) ** Wherein n has values of 2 to 4 and r as well as r'represent saturated or unbranched, branched or straight chain alkylic moieties, which together contain about 7 to 22 carbon atoms.

Abstract: 2-(perfluoroalkyl)-ethanols of the formula RfCH2CH2OH are obtained from 2-(perfluoroalkyl)-ethyl iodides of the formula RfCH2CH2I as a mixture with 2-(perfluoroalkyl)-ethylenes of the formula RfCH=CH2 and possibly also with 2-(perfluoroalkyl)-ethylcarboxylic acid esters of the formula RfCH2CH2OCOR. From these mixtures, the 2-(perfluoroalkyl)-ethanols are obtained with a high purity degree when adding during the distillation separation as entrainer an alkanol having from 1 to 8 carbon atoms or a monoalkyl ether of ethyleneglycol the alkyl radical of which contains 1 to 4 carbon atoms, or a mixture of such alkanols and/or alkylglycols, and in the presence of 2-(perfluoroalkyl)-ethylcarboxylic acid esters, furthermore an acidic ester interchange catalyst.
