SATURATED LINEAR POLYFLUOROHYDROCARBONS, METHOD OF THEIR SYNTHESIS (VARIANTS), COMPOSITION FOR SOLID SURFACE CLEANSING Russian patent published in 1997 - IPC

Abstract RU 2073664 C1

FIELD: organic chemistry, polymers. SUBSTANCE: product: compounds of the formulas and compositions including thereof. Invention relates to catalytic processes using metals of the VIII group and interaction of the selected parent olefins with hydrogen to synthesize dihydropolyfluoroalkanes or trihydropolyfluoroalkanes as the main products. Hydrogen atoms were located near two adjacent carbon atoms. Invention relates to methods of reduction of the selected parent olefins to dihydropolyfluoroalkanes and trihydropolyfluoroalkanes using iodine and/or hydrogen iodide. EFFECT: improved method of synthesis.
