    摘要: Methods are provided for cleaning a component having internal passages. A method includes contacting the component with an aqueous hydrogen fluoride solution without agitating the solution for a time period in a range of about 20 minutes to about an hour to dissolve a solid piece of blockage material blocking at least a portion of the internal passages, the aqueous hydrogen fluoride solution comprising, by volume, about 40 percent to about 60 percent hydrogen fluoride and optionally, a corrosion inhibitor, and the blockage material comprising a silicate and rinsing the component with water to remove at least a portion of the aqueous hydrogen fluoride solution from surfaces of the component defining at least a portion of the internal passages.

    摘要: Provided are azeotropic and azeotrope-like compositions of 1,2,3,3,3-pentafluoropropene (HFO-1225ye) and water. Such azeotropic and azeotrope-like compositions are useful in isolating 1,2,3,3,3-pentafluoropropene from impurities during production. Azeotropes of the instant invention are similarly useful in final compositions or manufacturing final compositions, such as blowing agent, propellants, refrigerants, diluents for gaseous sterilization and the like.
