The present invention aims to provide a method by which fluorine-containing sulfide compounds, particularly sulfide compounds that contain hydrogen and fluorine, can be produced in a simple, low-cost and industrial manner. Provided is a method of producing a fluorine-containing sulfide compound represented by the following formula (2):

(F).sub.n-A.sup.3-S-A.sup.4-(F).sub.m(2)

(wherein A.sup.3 and A.sup.4 are independently an optionally substituted hydrocarbyl group with a carbon number of 1 to 3; n and m represent the numbers of fluorine atoms binding to A.sup.3 and A.sup.4, with n+m=1 to 13 being satisfied), comprising reacting a chlorine-containing sulfide compound represented by the following formula (1):

(Cl).sub.n-A.sup.1-S-A.sup.2-(Cl).sub.m(1)

(wherein A.sup.1 and A.sup.2 are independently an optionally substituted hydrocarbyl group with a carbon number of 1 to 3; n and m represent the numbers of chlorine atoms binding to A.sup.1 and A.sup.2, with n+m=1 to 13 being satisfied) and a fluorinating agent.

Provided is a novel curable composition that is a two-pack type curable composition that includes an epoxy resin and a crosslinkable silicon group-containing organic polymer, excels in storage stability, and does not experience curing delays, an increase in viscosity of the base material, or the deterioration of the base material such as gelation or the deposition of insoluble material. Also provided is a novel curable composition that excels in storage stability even when water is added to improve deep portion curability. A two-pack type epoxy composition according to the present invention contains: a base material that includes (A) an epoxy resin, (B) a compound having an SiF bond, and (C) an alkoxysilane not having at least one group selected from the group consisting of a primary amino group, a secondary amino group, and a mercapto group; and a curing agent that includes (D) a crosslinkable silicon group-containing organic polymer, and (E) a tertiary amine compound.

Provided herein is a unique process that prepares a saturated hydrocarbon mixture with well-controlled structural characteristics that address the performance requirements driven by the stricter environmental and fuel economy regulations for automotive engine oils. The process allows for the branching characteristics of the hydrocarbon molecules to be controlled so as to consistently provide a composition that has a surprising CCS viscosity at 35 C. (ASTM D5329) and Noack volatility (ASTM D5800) relationship. The process comprises providing a specific olefinic feedstock, oligomerizing in the presence of a BF.sub.3 catalyst, and hydroisomerizing in the presence of a noble-metal impregnated, 10-member ring zeolite catalyst.

The present invention discloses processes for oligomerizing an olefin feedstock containing C.sub.4 to C.sub.20 alpha olefins using a catalyst system containing a metallocene compound, an organoaluminum compound, and a suspension of a chemically-treated solid oxide. The liquid medium for the suspension of the chemically-treated solid oxide can be an alpha-olefin oligomer product formed by the oligomerization process.

Silica-coated alumina activator-supports, and catalyst compositions containing these activator-supports, are disclosed. Methods also are provided for preparing silica-coated alumina activator-supports, for preparing catalyst compositions, and for using the catalyst compositions to polymerize olefins.

Methods for producing supported catalysts containing a transition metal and a bound zeolite base are disclosed. These methods employ a step of impregnating the bound zeolite base with the transition metal, fluorine, and high loadings of chlorine. The resultant high chlorine content supported catalysts have improved catalyst activity in aromatization reactions.
