摘要： 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.

摘要： A hollowed frusto-conical member has its base mounted adjacent the output of a laser. The apex portion extends outwardly from the laser output. The design of the member causes laser light to reflect many times as it travels from the base at a large aperture of the member down to the apex or focal point. The member may be made from light absorbing plastic material which absorbs most of the laser light and reflects only an infinitesimal portion.
