Process For Converting A Hydroxycarboxylic Acid, Or Salts Thereof, To An Unsaturated Carboxylic Acid And/Or Its Esters
US Patent:
7754916, Jul 13, 2010
Filed:
Sep 9, 2008
Appl. No.:
12/283050
Inventors:
Mark Anthony Silvano - New Hope PA, US
Donald L. Zolotorofe - Ivyland PA, US
Donald L. Zolotorofe - Ivyland PA, US
Assignee:
Rohm and Haas Company - Philadelphia PA
International Classification:
C07B 35/06
US Classification:
562599
Abstract:
A process for converting a salt of a hydroxycarboxylic acid to an unsaturated carboxylic acid, or esters thereof. The process involves converting an ammonium salt of a hydroxycarboxylic acid in aqueous solution to a corresponding hydroxycarboxylic acid and ammonium cation in aqueous solution; and separating the ammonium cation from the aqueous solution, leaving the hydroxycarboxylic acid in aqueous solution. The converting and separating steps may be accomplished by employing a hydrophobic acid or an acid ion exchange resin, each of which must have an acid dissociation constant, i. e. , pK, at least 0. 5 less that that of the salt of the hydroxycarboxylic acid. Where a hydrophobic acid is used, it must be immiscible in water, and its salt must also be immiscible in water, and the resulting multi-phase solution comprises an aqueous phase comprising the corresponding hydroxycarboxylic acid, as well as a non-aqueous phase comprising a neutralized acid. Alternatively, where the ion exchange resin is used, the aqueous solution of the ammonium salt of a hydroxycarboxylic acid is contacted with the resin, thereby converting the salt to a hydroxycarboxylic acid and capturing the ammonium cations on the resin. In either case, the aqueous solution is treated, such as by heating, to separate and recover the hydroxycarboxylic acid.

US Classification:
585654, 585661, 585656, 585659
Abstract:
A method for producing a mixture of ethylene and carbon monoxide by contacting ethane and an oxygen source at a temperature of at least 500 C. to produce ethylene and carbon monoxide. A method for producing an alkyl propionate by steps of: (a) contacting ethane and an oxygen source at a temperature of at least 500 C. to produce ethylene; (b) contacting an alcohol, ethylene and carbon monoxide with an ethylene carbonylation catalyst to produce the alkyl propionate; and (c) separating the alkyl propionate from byproducts and starting materials. The method further comprises condensing the alkyl propionate with formaldehyde to produce an alkyl methacrylate.

Process For Production Of Acrolein From Glycerol
US Patent:
8198477, Jun 12, 2012
Filed:
Nov 20, 2009
Appl. No.:
12/592182
Inventors:
Mark Anthony Silvano - New Hope PA, US
International Classification:
C07C 51/16
C07C 45/00
C07C 45/00
US Classification:
562532, 568486
Abstract:
The present invention relates to a process for producing acrolein by liquid phase dehydration of glycerol by preparing a mixture of a catalyst suspended in an organic solvent comprising one or more vinyl polymers and glycerol; and then mixing and heating the mixture to between 150 C. and 350 C. to dehydrate the glycerol and form acrolein. The vinyl polymers are selected from the group consisting of polyolefins, polystyrene, and mixtures thereof. The polyolefins may be polyethylene, polypropylene, polybutylene, polyisobutylene, polyisoprene, polypentene, or mixtures thereof. The acrolein may be subjected to vapor phase oxidation in the presence of a catalyst, such as a mixed metal oxide, to produce acrylic acid.
