  • Patent number: 10173960
    Abstract: An object of the present invention is to provide a method for stabilizing an acrylic acid derivative, and a composition containing an acrylic acid derivative in which the acrylic acid derivative is stabilized. The present invention provides a composition comprising: (A) an acrylic acid derivative represented by Formula (I): (wherein Ra represents alkyl, fluoroalkyl, aryl that may have one or more substituents, or hydrogen; and X represents fluorine, alkyl, perfluoroalkyl, or hydrogen); and (B) aldehyde, wherein the content of acrylic acid derivative (A) is 30% (w/w) or more.
    Type: Grant

  • Patent number: 9950984
    Abstract: An object of the present invention is to provide a process for producing ?-fluoroacrylic acid esters at a high starting material conversion and a high yield. The present invention provides, as a means to achieve the object, a process for producing a compound represented by formula (1): wherein R1 and R2 are the same or different and each represent alkyl, fluoroalkyl, aryl optionally substituted with at least one substituent, halogen, or hydrogen; and R3 represents alkyl, fluoroalkyl, or aryl optionally substituted with at least one substituent, the process comprising step A of reacting a compound represented by formula (2): wherein the symbols are as defined above, with carbon monoxide and an alcohol represented by formula (3): R3—OH??(3) wherein the symbol is as defined above, in the presence of a transition metal complex catalyst containing at least one bidentate phosphine ligand and a base to thereby obtain the compound represented by formula (1).
