Abstract: Xylene isomerization processes, especially those processes in which ethylbenzene is also converted, are beneficially affected by adding benzene to the feed.

Abstract: Processes and apparatus are provided that provide high yields of xylenes per unit of aromatic-containing feed while enabling a high purity benzene co-product to be obtained without the need for an extraction or distillation to remove C6 naphthenes. The processes of this invention include a transalkylation section and a disproportionation section in the benzene and toluene-containing feed is directly provided to the transalkylation section and in which a benzene recycle loop in the transalkylation section isolates the disproportionation section from C6 naphthenes.

Abstract: An improved process is disclosed for ethylbenzene and xylene isomerization in a non-equilibrium mixture of xylenes and ethylbenzene. By addition of trace quantities of water to the reaction zone, equivalent isomerization is effected at lower temperatures wherein benefits could be realized in reduced losses and improved catalyst life.

Abstract: D-allose has been found to substantially inhibit segmented neutrophil production and to lower platelet counts during in vivo trials, without other significant detrimental clinical effects. Such pharmacological activity makes D-allose a good candidate for treatment, either alone or as an adjuvant, of such conditions as chronic myelogenous leukemia. It also holds promise in reducing thrombus formation during post-operative periods, especially in combination with other anti-clotting drugs.
