METHOD OF PREPARING POLYFLUOROALKYL METHYL KETONES Russian patent published in 1999 - IPC

Abstract RU 2143420 C1

FIELD: organic chemistry, more particularly, chemical and pharmaceutical industries. SUBSTANCE: described is method of preparing polyfluoroalkylmethyl ketone of general formula I: R_FC(O)CH₃ wherein by hydrolysis of fluorine-containing esters in the presence of sulfuric acid on heating. Original products include polyfluorinated esters of enol beta-diketones, and process is carried out at temperature of 100-200 C in the presence of 94-98% sulfuric acid. EFFECT: more efficient method of preparing polyfluoroalkylmethyl ketones with high yield. 8 ex
