US Patent:

20110076387, Mar 31, 2011
Filed:

Sep 29, 2009
Appl. No.:

12/569564
Inventors:

David Joseph Koehl - Bethlehem PA, US
Joseph Kimler - Yardville NJ, US
Larry Kent Hall - Easton PA, US
Philip Gerdon Sweeny - Hackettstown NJ, US
Assignee:

LONZA, INC. - Allendale NJ
International Classification:

B05D 3/02
B05D 3/06
US Classification:

427 231, 4273855, 427536, 4273899
Abstract:

The present invention relates to a method for imparting antibiotic activity to a surface of a solid substrate by exposing a solid substrate composition to conditions suitable for covalent grafting and thermal polymerization of the substrate.

Alkylation Process Of Alkyl-Benzene With Olefin Using A Sodium-And-Potassium Catalyst
view source
US Patent:

61004375, Aug 8, 2000
Filed:

Jul 10, 1998
Appl. No.:

9/113650
Inventors:

David J. Koehl - Orangeburg SC
Edward A. Burt - Lexington SC
Patrick T. Ward - Austin TX
Assignee:

Albemarle Corporation - Richmond VA
International Classification:

C07C 264
C07C 15067
C07C 266
US Classification:

585452
Abstract:

An alkylbenzene is alkylated with an alkene, in the presence of a sodium/potassium alloy catalyst, on a saturated carbon atom which is alpha to the ring at temperatures which are lower than the temperatures used in a current commercial process. In a pre-alkylation reaction, the catalyst is reacted with a compound which has a saturated carbon atom alpha to a double bond in order to form a catalytic species. Higher amounts of catalyst are used in the pre-alkylation reaction than in the analogous reaction of the current commercial process. Following alkylation, the phase which contains the alkylation product is separated from the phase which contains the catalytic species. The process produces less isomeric and other soluble byproducts, and enables the efficacious production of longer chain alkylbenzenes without the formation of insoluble tars characteristic of the current commercial process.
