A titania bound ion exchange composition is prepared by admixing crystalline sodium titanate and a hydrolyzable titanium compound and then drying the titania bound crystalline sodium titanate. The dried titania bound ion exchange composition is subjected to optional compaction and calcination steps to improve the physical strength of the titania bound composition.

Titania bound sodium titanate ion exchanger

This invention is method for preparing a titania bound ion exchange composition comprising admixing crystalline sodium titanate and a hydrolyzable titanium compound and, thereafter drying the titania bound crystalline sodium titanate and subjecting the dried titania bound ion exchange composition to optional compaction and calcination steps to improve the physical strength of the titania bound composition.

A method for converting Explosive D, i.e., ammonium picrate to oxygenated products, particularly hydroquinone or cyclohexanediol and ammonia by hydrogenation over a supported Group VIII metal catalyst. Preferably, the ammonium picrate is dissolved in a suitable solvent and then hydrogenated at a temperature of about 25.degree. to 250.degree. C., and a pressure of about 10 to 1000 psig (69 to 6900 kPa gauge) followed by separation of the commercially valuable products and ammonia.

Disposal of explosive D

The instant invention is a membrane useful for separating organic matter such as proteins from aqueous solutions which resists fouling and maintains a high flux during separation. The membrane is prepared by either drying a polysulfone composite membrane, or first treating a polysulfone composite membrane with aqueous methanol and then drying it. The membrane is then exposed to elemental fluorine in an inert gas in the substantial absence of oxygen at a temperature in the range of about -45.degree. to 70.degree. C. After fluorine treatment, the membrane is exposed to air. The fluorine content in the treatment mixture may be from 0.0125 to about 10 volume percent, preferably 0.025 to 2 volume percent. The fluorine treatment does not significantly alter the membrane pore size.
