  • Publication number: 20090137853
    Abstract: A process for the manufacture of CF3CH2CHF2 and/or CF3CH2CF3 is disclosed. The process involves (a) reacting HF and at least one halopropene of the formula CX3CCI?CCIX (where each X is independently F or Cl) to produce a product including both CF3CCI?CF2 and CF3CHCICF3; (b) reacting CF3CCI?CF2 and/or CF3CHCICF3 produced in (a) with hydrogen to produce a product including CF3CH2CHF2 and/or CF3CH2CF3; and (c) recovering CF3CH2CHF2 and/or CF3CH2CF3 from the product produced in (b). In (a), the CF3CCI?CF2 and CF3CHCICF3 are produced in the presence of a fluorination catalyst comprising at least one chromium-containing component selected from (i) a crystalline alpha-chromium oxide where at least 0.05 atom % of the chromium atoms in the alpha-chromium oxide lattice are replaced by divalent copper, and (ii) a chromium-containing composition of (i) which has been treated with a fluorinating agent.

  • Patent number: 7028760
    Abstract: A heat pipe with superior heat transfer between the heat pipe and the heat source and heat sink is provided. The heat pipe is held tightly against the heat source by mounting holes which penetrate the structure of the heat pipe but are sealed off from the vapor chamber because they each are located within a sealed structure such as a pillar or the solid layers of the casing surrounding the vapor chamber. Another feature of the heat pipe is the use of a plurality of particles joined together by a brazing compound such that fillets of the brazing compound are formed between adjacent ones of the plurality of particles so as to form a network of capillary passageways between the particles of the wick.
