US Patent:

43563112, Oct 26, 1982

Filed:

Dec 21, 1981

Appl. No.:

6/332782

Inventors:

Steven E. Diamond - New Providence NJ
Frank Mares - Whippany NJ
Deborah A. Muccigrosso - Somerville NJ
Jeffrey P. Solar - Flanders NJ

Assignee:

Allied Corporation - Morris Township, Morris County NJ

International Classification:

C07D30103

US Classification:

549524

Abstract:

An olefinically unsaturated substrate is reacted with a transition metal nitro complex, having the transition metal bonded to the nitrogen of the nitro radical, in the presence of a thallium(III) compound as cocatalyst to cause the production of oxirane products, rather than aldehydes or ketones. The process is applicable to the production of ethylene oxide, propylene oxide, epichlorohydrin, epoxidized fatty acids and oxiranes from various other internal and terminal olefins.

International Classification:

B01J 800
C01B 2100

US Classification:

423239

Abstract:

Catalysts for the selective catalytic reduction of NOx by ammonia are made from porous formed supports having a certain fraction of the pores with pore diameters larger than 600 Angstrom units. Thus macropores can be introduced in a formed TiO. sub. 2 support by adding burnout materials or some inorganic oxide prior to forming the titania into the formed support. Alternatively, titania is precipitated onto a porous inorganic oxide such as SiO. sub. 2, Al. sub. 2 O. sub. 3, ZrO. sub. 2, AlPO. sub. 4, Fe. sub. 2 O. sub. 3 and B. sub. 2 O. sub. 3 to form the support. Then conventional DeNOx catalytic metals are added. The support can be made by first impregnating the inorganic oxide particles with titania via a soluble precursor, forming titania and then shaping the coated particles into the desired shape such as a monolith. In a second embodiment, the inorganic oxide particles are first formed into the desired shape and then impregnated with the titania forming material. Barium sulfate can be added to the surface of the porous inorganic oxide to make an improved support.
