  • Transesterification process
    Patent number: 9416092
    Abstract: A transesterification process produces a (meth)acrylate ester product from a mixture comprising an alkyl(meth)acrylate reactant, an alcohol reactant, a catalyst, and a polymerization inhibitor. The mixture is subjected to reaction conditions sufficient to produce a product (meth)acrylate and a product alcohol, which are different than the reactants.
    Type: Grant
    Filed: February 11, 2013
    Date of Patent: August 16, 2016
    Assignee: Rohm and Haas Company
    Inventors: David A. Flosser, Philippe P. Maillot, Nawal K. Sharma, Alejandro Ceron, Mingyu Ye
  • Transesterification process
    Patent number: 9394224
    Abstract: A transesterification process produces a (meth)acrylate ester product from a mixture comprising an alkyl(meth)acrylate reactant, an alcohol reactant, a catalyst, and a polymerization inhibitor, wherein the water content in the reaction zone at the start of the transesterification step is from 0.2 to 1.1 weight percent, based on the weight of the materials in the reaction zone. The mixture is subjected to reaction conditions sufficient to produce a product (meth)acrylate and a product alcohol, which are different than the reactants.
