    Abstract: Tertiary butyl hydroperoxide and tertiary butyl alcohol are prepared from isobutane and oxygen in a vertical reactor by sparging a mixture of isobutane with oxygen to the bottom of the reactor, by charging a reaction mixture recycle stream to the reactor above the sparge point, by centrally charging a downwardly flowing stream of cooled fresh isobutane to the top of the reactor to induce central downflow of the fresh isobutane annular and upflow of the sparged mixture and the recycle stream, by withdrawing a liquid product stream adjacent the top of the reactor, by withdrawing a vapor product stream from the top of the reactor, by condensing entrained liquids in the vapor product, by recycling the condensed liquids and by recovering the liquid product stream.

    Abstract: A polymerization method carried out in the presence of unsaturated hydroperoxides useful as molecular weight regulators, is disclosed. Also disclosed are polymers and oligomers made by this process and articles of manufacture comprising one or more polymers or oligomers made by this process. These molecular weight regulating hydroperoxides provide the ability to introduce an epoxy functionality to the oligomer or polymer as well as an additional functionality and a primary hydroxy group. Further, omega substituted or alpha, omega disubstituted polymers may be synthesized using the unsaturated hydroperoxides of the present invention.

    Abstract: The distillation product fraction obtained from an isobutane oxidation reaction product after the removal of unreacted isobutane will contain tertiary butyl hydroperoxide, tertiary butyl alcohol and carboxylic acid contaminants such as formic acid, acetic acid and isobutyric acid. It has been discovered that when the distillation product fraction is treated with about 1/2 to 1 equivalents of calcium oxide and/or calcium hydroxide based on the carboxylic acid content of the distillate product fraction, a portion of the carboxylic acid contaminants will precipitate thus partially purifying the distillation product fraction so that, thereafter, molybdenum precipitation will be substantially inhibited when the thus-treated distillation product fraction is used as a feedstock for an epoxidation reaction wherein tertiary butyl hydroperoxide is reacted with an olefin in the presence of a soluble molybdenum catalyst to provide an olefin epoxide and additional tertiary butyl hydroperoxide.
