The present invention is directed to the preparation of oxygenated, unsaturated hydrocarbon compounds, such as derivatives of furfural or hydroxymethyl furfural produced by aldol condensation with a ketone or a ketoester, as well as methods of deoxidatively reducing those compounds with hydrogen under acidic conditions to provide saturated hydrocarbons useful as fuels.

Lewis Bases are used to control the activity of an olefin polymerization reaction and, if need be, to substantially terminate the entire reaction completely. Such activity reduction or termination of the reaction by the one or more Lewis Bases can be completely reversed by the simple introduction of additional co-catalyst. The use of such Lewis Bases to control static is also disclosed.
There is provided a method for reducing or suppressing the formation of gels, oligomers, or both in a gas phase polymerization of at least one olefin or diolefin monomer conducted in the presence of a vanadium catalyst, which method comprises the addition of at least one sacrificial monomer or Lewis base.

An object of the present invention is to obtain an aqueous dispersion of polytetrafluoroethylene in which compounds containing fluorine are removed or reduced. The present invention is a method for producing an aqueous dispersion of purified polytetrafluoroethylene, the method including: removing or reducing a compound represented by Formula (1) or (2) below from an aqueous dispersion of polytetrafluoroethylene obtained using a hydrocarbon surfactant:
Formula (1): (H-(CF2)m-COO)pM1; or
Formula (2): (H-(CF2)n-SO3)qM2.
