  • Patent number: H2211
    Abstract: Fluorinated ketones, for example, 1,1,1-trifluoroacetone, can be stabilized against storage degradation by combining with a content of hexafluoroisopropanol (HFIP). Containers containing the stabilized mixture show prolonged storage times compared to containers containing the fluorinated ketones alone. The stabilized mixture can be used as a starting material for reactions requiring fluorinated ketones, for example, 1,1,1-trifluoroacetone, as a starting material.
