标 题 :Method for the synthesis of acrylic (co)polymers from oligomers of acrylic acid
发明人：SUAU JEAN-MARC; CHAMPAGNE CLEMENTINE
权利人:ARKEMA FRANCE
摘要:The present invention relates to the synthesis of an associative acrylic (co)polymer by aqueous emulsion radical polymerization. The (co)polymer contains at least one oligomer of acrylic acid represented by the formula (I): n nwhere n is an integer ranging from 1 to 10. The oligomer is prepared from acrylic acid at a temperature of between 50° C. and 200° C. in the presence of a basic or acid catalyst, water, and polymerization inhibitors. The present invention also relates to the associative acrylic (co)polymer obtained from the method and also to the use of this (co)polymer as a thickener in various formulations.

标题:Direct biocatalytic production of acrylic acid and other carboxylic acid compounds
发明人：VALLE FERNANDO; AGARD NICHOLAS JOHN; NORIEGA CHRISTOPHER
权利人:CODEXIS INC
摘要:The present disclosure relates to biocatalytic methods or processes for the synthesis of acrylic acid and its derivatives, or other carboxylic acid compounds of the formula R—CO2H, wherein R is a carbon chain of 5 carbons or fewer, such as methacrylic acid or 3-hydroxypropionic acid. More specifically, the disclosure relates to methods of using an acyl-CoA hydrolase (such as a thioesterase) as a biocatalyst for the hydrolysis (and removal of the CoA moiety) of a substrate acyl-CoA compound to produce the corresponding carboxylic acid compound, such as acrylic acid. In some embodiments, the disclosure provides non-naturally occurring microorganisms that have been transformed with a heterologous acyl-CoA hydrolase, such as a thioesterase, that is capable of hydrolyzing an acyl-CoA produced in a pathway of the microorganism and produce the corresponding carboxylic acid compound, thereby allowing methods for the direct fermentative production of the compound.

摘要:The invention relates to a biocatalytic method or process for the synthesis of esters of acrylic acid and/or methacrylic acid free of positively chargeable/charged groups, comprising reacting one or more alcohols (alcohol starting materials) which are free of positively chargeable or charged groups with (meth)acrylyl-CoA, preferably in the presence of a catalyst (inorganic, organic or organometallic, or preferably a biocatalyst) capable of effecting the transfer of an alcohol radical from an alcohol starting material as defined above or below to (meth)acrylyl CoA under removal of the CoA moiety transferase activity, such as an enzyme of the transferase or hydrolase class of enzymes. The (meth)acrylyl-CoA is preferably formed by reaction of (meth)acrylic acid or its salts with coenzyme A in the presence of an energy providing substance and a biocatalyst e.g. with S-acetyl coenzyme A synthetase activity or by reaction of acrylate or methacrylate produced metabolically in the presence of a biocatalyst or metabolically.

标题:Effects of catalyst concentration and solid activator on nickel-mediated olefin/carbon dioxide coupling to acrylates
发明人：Iacono Pasquale; HLAVINKA MARK L
权利人:CHEVRON PHILLIPS CHEMICAL CO LP
摘要:This disclosure provides for routes of synthesis of acrylic acid and other α,β-unsaturated carboxylic acids and their salts, including catalytic methods. For example, there is provided a process for producing an α,β-unsaturated carboxylic acid or a salt thereof, the process comprising: (1) contacting in any order, a group 8-11 transition metal precursor, an olefin, carbon dioxide, a diluent, and a metal-treated chemically-modified solid oxide such as a sulfur oxoacid anion-modified solid oxide, a phosphorus oxoacid anion-modified solid oxide, or a halide ion-modified solid oxide, to provide a reaction mixture; and (2) applying reaction conditions to the reaction mixture suitable to produce the α,β-unsaturated carboxylic acid or the salt thereof. Methods of regenerating the metal-treated chemically-modified solid oxide are described.
