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.
