摘要:Synthesis of tungsten pentahalide compositions having low impurity profiles are disclosed. The specific impurity profile permits deposition of high purity tungsten-containing films using vapor deposition processes or other semiconductor manufacturing processes without introduction of performance-impacting contaminants.

摘要:A method of synthesizing 2,3,3,3-tetrafluoropropene (1234yf) from 2-chloro-3,3,3-trifluoropropene (1233xf). The 2-chloro-3,3,3-trifluoropropene (1233xf) is reacted in the vapor phase, in the presence of a catalyst, at a temperature and pressure sufficient to selectively convert the 2-chloro-3,3,3-trifluoropropene (1233xf) to 2,3,3,3-tetrafluoropropene (1234yf) without the use of antimony-based catalysts.

摘要:A method of manufacturing a fluorinated polyhedral oligomeric silsesquioxane. The method for manufacture includes opening a single edge of a closed-cage F-POSS and bridging the opened, single edge with a sulfate group. The sulfate group is converted to a disilanol, which is then reacted with a functional dichlorosilane having an organic functional group comprising at least three carbon atoms.

摘要:In an embodiment, a method of producing a fluoroolefin comprises coupling 3,3-dichloro-1,1,1,2,2-pentafluoropropane (CF3—CF2—CHCl2) in a liquid phase in the presence of a catalyst to form a composition comprising 1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene (CF3CF2CHâ•?CHCF2CF3). In another embodiment, a method of producing a fluoroolefin comprises coupling 1,1,1-trichloropentafluoropropane (CF3—CF2—CCl3) in a vapor phase in the presence of a first catalyst to form a composition comprising 3,4-dichloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene (CF3—CF2—CClâ•?CCl—CF2—CF3). The method may further include forming the CF3—CF2—CCl3 in a vapor phase from CF3CF2CHmCl3-m and chlorine (Cl2). The method may further include hydrodechlorinating the 3,4-dichloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene with hydrogen (H2) in a vapor phase in the presence of a second catalyst to form a composition comprising CF3CF2CHâ•?CHCF2CF3 and 3-chloro-1,1,1,2,2,5,56,6,6-decafluoro-3-hexene (CF3CF2CClâ•?CHCF2CF3).
