Acrylate monomer preparation using alkali metal alkoxides as ester interchange catalysts |
摘要 |
The present invention relates to a process to prepare alkyl (meth)acrylate esters from corresponding alkyl/methacrylate esters using an alkali metal alkoxide as an ester interchange catalyst to produce an alkyl (meth)acrylate ester monomer product C <CHEM> The present invention further relates to the use of bromide and iodide salts as free radical polymerization inhibitors. The present invention further relates to the use of a noninterfering alcohol or polyol that prevents anionic polymerization reactions of reactant ester B and/or alkyl (meth)acrylate product C. The present invention further relates to a process for inhibiting polymerization of (meth)acrylates being synthesized in a transesterification or ester-ester interchange reaction system
