PREPARATION AND EVALUATION OF NEW HYDRAULIC FLUIDS.
Abstract
A larger Simon's cell has been constructed for use in the preparation of sufficient amounts of CF3-SF4-CF2-CF2-SF4-CF3 and (CF2SF4)3. The cell is now operating, and the fluorination of strithiane was carried out in an attempt to prepare the perfluorinated compound (CF2SF4)3. A new method is being used in an attempt to prepare pentafluorophenysulfur pentafluoride, by reacting C6F5MgBr and SF5C1. Correlations have been made to determine the effect of structure on the viscosity-temperature relationship. Although it is realized that other important variables such as molecular weight must be included in order to make the correlations complete, certain trends are evident: (1) aromatic compounds are better than cyclics; (2) esters seem to be better than substituted paraffins; (3) the -CH-CF-SF5 groups seem to be desirable; and (4) ethers and OSF5 compounds do not look promising.
