Abstract: Disclosed is an optimized process and apparatus for more efficiently and economically carrying out the liquid-phase oxidation of an oxidizable compound. Such liquid-phase oxidation is carried out in a bubble column reactor that provides for a highly efficient reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product from the oxidation reaction is crude terephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than could be employed if the CTA were formed by a conventional high-temperature oxidation process.

Abstract: A portable patient support includes a platform having a rigid platform received in an interior of an end cap. Elongated rails attached to side walls of the end cap receive accessories, such as stirrups for elevating a patient's legs during insertion of brachytherapy needles for treating prostate cancer and a leg support table for comfortable support of a patient's legs during transport. The portable patient support also has a transfer device including an inflatable mattress having micro-fenestrations in a bottom sheet or a semi-rigid sliding member located beneath the platform. The platform is preferably secured to the transfer device, using straps or by receipt of the platform in built-in pocket. Alternatively, the support may include a fenestrated lower tray attached to the platform by expandable connectors to contain the transfer device. A method of preparing a patient for prostate brachytherapy using the portable patient support is described.
