Peroxide bleaching agent compositions
Patent
Report
The title compound is prepared by contacting with a ZSM-5 zeolite catalyst of Si02/Alz03
Aromatization
cyclohexanone ratio 2 12.
Treating zeolite A particles with an ammonium or substituted ammonium compound and heating to reduce the water cantent to < 24% gives activated particles that have a reduced tendency to catalyze the decomposition of liquid detergent components such as bleach precursors used with inorganic persalts in bleach systems.

Exhaust gases from internal-combustion engines are treated in a system comprising a catalyst bed of Cu-exchanged zeolite beads for removing NO,, CO, and hydrocarbons from the exhaust gases, and means for controlling the air/fuel ratio at s 14.6:1 while injecting air into the catalyst bed. The method prevents degradation of the catalyst bed.

The components of a gas mixture are separated by contacting the mixture with Li-exchanged chabazite having a Si/AI ratio of 2.1-2.8, where L 65% of the exchangeable ion capacity is in the Li form, thereby facilitating the chabazite to selectively adsorb the component with higher heat of adsorption from the mixture. The process can be used for separation of N from air by pressure-swing adsorption.

A dry mixture of a finely divided crystalline zeolite and a K or Na salt of a carboxy-containing polymer is treated with water to prepare granules that contain zeolite 60-80, polymer 2-15, and water 1425%, have high bulk density, high adsorption capacity for liquid or waxy detergent components such as non-ionic sutfactants, and disintegrate rapidly in water. The granules are useful in laundry detergent compositions, leaving no residue in washing machines or on fabrics.

Poly[ethylene terephthalate] films, having fewer defects, and useful for packaging and audio and video tapes, are prepared by polymerization of bis(2-hydroxyethyl)terephthalate in the presence of a catalyst and a slip additive comprising a Na aluminosilicate zeolite having average particle size 0.5-2.0 microns. The use of the zeolite eliminated the need for Sbz03 polymerization catalyst and reduced the amount of ‘diethylene glycol normally found during polymerization.
