8283500, Oct 9, 2012

Filed:

Feb 9, 2006

Appl. No.:

11/815673

Inventors:

Paul Mazzell - Aiken SC, US
Barry Jones - Martinez GA, US
Neville Pavri - Evans GA, US
Joel Swinson - Evans GA, US

Assignee:

Halocarbon Products Corporation - River Edge NJ

International Classification:

C07C 43/00

US Classification:

568683, 568681, 568682

Abstract:

An azeotrope comprising desflurane (CFCFHOCFH) and hydrogen fluoride (HF). The azeotrope can be prepared by fractionally distilling a crude mixture of desflurane and HF. Purer desflurane can be readily and easily separated from the azeotrope. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader quickly to ascertain the subject matter of the technical disclosure.

Assignee:

HALOCARBON PRODUCTS CORPORATION - River Road NJ

International Classification:

Appl. No.:

11/687774

Inventors:

Neville Pavri - Evans GA, US
Danny Graham - Martinez GA, US
Mark Harris - N. Augusta SC, US
Paul Mazzell - Aiken SC, US

Assignee:

Halocarbon Products Corporation - River Edge NJ

International Classification:

C07C 45/86

US Classification:

568304

Abstract:

Fluorinated ketones, for example, 1,1,1-trifluoroacetone, can be stabilized against storage degradation by combining with a content of hexafluoroisopropanol (HFIP). Containers containing the stabilized mixture show prolonged storage times compared to containers containing the fluorinated ketones alone. The stabilized mixture can be used as a starting material for reactions requiring fluorinated ketones, for example, 1,1,1-trifluoroacetone, as a starting material.
