Page/Page column 22, (2008/06/13)
A hydrofluoroether compound comprises two terminal fluoroalkyl groups and an intervening substituted or unsubstituted oxymethylene group, each of the fluoroalkyl groups comprising only one hydrogen atom and, optionally, at least one catenated (that is, in-chain) heteroatom; with the proviso that the hydrogen atom is part of a monofluoromethylene moiety.

Present invention relates to a process for the manufacture of fluorinated alcohols as well as borates which are employed in the manufacture of the fluorinated alcohols. Fluorinated alcohols of the formulae HOCHRCF(CF3)CHFCF(CF3)2 and HOCHRCF(CF(CF3)2)CHFCF3, HOCHRCF(CF2CF3)CH(CF3)2 and HOCHRC(CF3)2CHFCF2CF3 are made by heating a mixture of a borate of the formula (RCH2O)3B, wherein R═H or a C1 to C7 alkyl group, with perfluoro-4-methyl-2-pentene or perfluoro-2-methyl-2-pentene and a free-radical initiator to form a mixture of borates, optionally separating the mixture of borates from any reactants, solvents, and by-products; hydrolyzing the mixture of borates to form a hydrolysis product mixture; and separating the alcohols from the hydrolysis product mixture.
