Filed:

Sep 12, 2003

Appl. No.:

10/661724

Inventors:

Joel Tenney - Marietta GA, US
Tom Isaac - Newnan GA, US
William Ernst - Roswell GA, US

Assignee:

ICA Trinova, LLC - Forest Park GA

International Classification:

A01N 25/08
A01N 25/12
A01N 59/04
A01N 59/16
A01N 37/02

US Classification:

424 84, 424409, 424647, 424666, 424700, 424715, 424716, 424717, 514557, 431321

Abstract:

The invention is a method for attracting mosquitoes by producing a volatilized acid by combining an acid precursor with water to produce the humidified vapor acid attractant, preferably hydrogen chloride. The humidified volatilized acid can be further combined with carbon dioxide, or carbon dioxide can be simultaneously produced to attract mosquitoes. The acid precursor can be a hydrate of ferric chloride, such as ferric chloride hexahydrate. The acid precursor can be impregnated in a carrier, and can be combined with water through exposure to water vapor in the atmosphere, the intentional addition of water, or water produced by a chemical reaction.

International Classification:

A23L 3/3427

US Classification:

423438, 25218311, 25218316, 25218625, 25218636, 426263

Abstract:

The invention is a method and composition for producing carbon dioxide that is based on the reaction or activation of at least one carbon-containing compound with protons. The carbon-containing compound can be in the form of a powder, an impregnated carrier (e. g. zeolite crystals) or an aqueous solution and is preferably selected from the group consisting of carbonates, bicarbonates or sesquicarbonates. The protons are preferably provided by a proton-generating species such as an acid or metal salt. The method and composition can further include a water-retaining substance and/or a chlorine dioxide-producing compound in accordance with the invention.

Filed:

Jul 8, 1983

Appl. No.:

6/512288

Inventors:

Michael S. Chen - Zionsville PA
Thomas J. Edwards - Allentown PA
William R. Ernst - Roswell GA

Assignee:

Air Products and Chemicals, Inc. - Allentown PA

International Classification:

C01B 1700

US Classification:

423243

Abstract:

Hydrolysis of COS in gas streams to H. sub. 2 S and CO. sub. 2 can be improved by using certain bicyclo tertiary amine catalysts. Bicyclo tertiary amine catalysts can enhance COS hydrolysis in an acid gas removal solvent in the liquid phase or on a solid support system in the gas phase.
