Abstract: A method of separating a composition containing at least one organofluorine compound from at least one inorganic compound by contacts the composition with a semipermeable membrane. Other methods separate a organofluorine compound from a composition containing at least one other organofluorine compound or chlorocarbon. Methods also include isolating a single organofluorine compound from a composition comprising a mixture of organofluorine compounds, chlorocarbons, and/or inorganic compounds.

Abstract: A stable polyol pre-mix composition comprises a blowing agent, a polyol, a surfactant, and a catalyst composition comprising an oxygen-containing amine catalyst and a metallic salt. The oxygen-containing amine catalyst may be, for example, one or more of an alkanol amine, an ether amine, or a morpholine group-containing compound such as, for example, 2-(2-dimethylaminoethoxy)ethanol or N,N,N′-trimethylaminoethyl-ethanolamine. The metallic salt may be, for example, alkali earth carboxylates, alkali carboxylates, and carboxylates of metals selected form the group consisting of zinc (Zn), cobalt (Co), tin (Sn), cerium (Ce), lanthanum (La), aluminum (Al), vanadium (V), manganese (Mn), copper (Cu), nickel (Ni), iron (Fe), titanium (Ti), zirconium (Zr), chromium (Cr), scandium (Sc), calcium (Ca), magnesium (Mg), strontium (Sr), and barium (Ba)

Abstract: A polyol pre-mix containing at least one halogenated hydroolefin blowing agent and having improved shelf life stability is provided, wherein each polyol combined with the halogenated hydroolefin blowing agent has an apparent pH of between 3 and 11.4. Controlling the apparent pH of the polyol(s) enables the polyol pre-mix to be stored for extended periods of time and then used in combination with organic polyisocyanate to produce foam formulations having gel times and tack free times not significantly different from those exhibited when freshly prepared polyol pre-mix is used.

Abstract: A fluorination catalyst such as a chromium oxide-based fluorination catalyst may be activated or reactivated by contacting the catalyst. with a source of reactive fluorine, for example nitrogen trifluoride (NF3) or fluorine (F2). Fluorinated compounds may be prepared by the gas phase reaction of hydrogen fluoride (HF) with various substrates such as chlorinated compounds. A number of metal oxide-based catalysts have been developed for this purpose.
