20090082587 | Process for chemical reactions involving cyanohydrins - The present invention provides a method for minimizing the decomposition of cyanohydrins in exothermic chemical reactions involving cyanohydrins. The method comprises providing a reaction medium and reactants to a tubular reactor having internal mixing means, mixing the reaction medium and reactants to form a homogenous reaction mixture, removing heat from the reaction process and reacting the reactants to produce a mixed product having a bulk temperature. The method may further comprise cooling the reaction medium to a temperature from 1-10° C. cooler than the bulk temperature of the mixed product prior to providing the reaction medium to the tubular reactor. | 03-26-2009 |

20090076297 | Process for converting a hydroxycarboxylic acid, or salts thereof, to an unsaturated carboxylic acid and/or its esters - 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 | 03-19-2009 |

20090048411 | Processes for producing ethylene and carbon monoxide mixtures from ethane - 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. | 02-19-2009 |
