<p>This invention utilizes a mixed salt transesterification catalyst in a transesterification process for the production of esters of alkyl (meth)acrylate monomers.
For example, when the reactant alcohol is hydroxyl alkyl imidazolidin-2-one, having the following Formula IV:
<Chemistry id="chema01" num="0001"><Image id="ia01" he="33" wi="85" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" /></Chemistry>
wherein R" = C<Sub>1</Sub>-C<Sub>8</Sub> straight, branched or cyclic, and saturated or unsaturated, hydrocarbon, then the product (math)acrylate ester has Formula V as follows:
<Chemistry id="chema02" num="0002"><Image id="ia02" he="39" wi="107" file="IMGA0002.TIF" imgContent="chem" imgFormat="TIFF" /></Chemistry>
wherein R = H or CH<Sub>3</Sub>, and R" = C<Sub>1</Sub>-C<Sub>8</Sub> straight, branched or cyclic, and saturated or unsaturated, hydrocarbon.
The present invention also provides a mixed salt transesterification catalyst comprising at least two salts wherein at least one of the at least two salts is a base.</p> |
