catalysts by using a filter aid depending on the final product specifications excess mma was stripped out by applying full vacuum during the required time or mma was added to the system and the solution is mixed for homogenization comparative examples utilizing typical catalysts were prepared against the catalyst systems as descried herein comparative examples as shown in table 1 are as follows r 1094 135 28 r 1094 116 28 and r 1094 133 28 which utilize lioh and cao as the catalyst system as can be seen from table 1 the comparative examples have a high conversion of final product i e compound of formula i when the molar ratio is high at 5 1 of maa heeu respectively 87 79 conversion the comparative examples utilize 277 ppm lioh 724 ppm cao the catalyst system of the present invention 250 ppm lioh 300 ppm cao had a higher conversion at the same 5 1 weight ratio of maa heeu respectively 89 conversion however when using a ratio 3 1 of maa heeu respectively the conversion of final product i e compound of formula i of the comparative example is at a low 66 conversion the catalyst system of the present invention 250 ppm lioh 300 ppm cao had a much higher conversion at the same 3 1 weight ratio of maa heeu respectively 85 conversion versus a 66 conversion rate of the comparative example the present invention therefore is well adapted to carry out the objects and attain the ends and advantages mentioned as well as others inherent therein while the invention has been depicted and described and is defined by reference to particular preferred embodiments of the invention such references do not imply a limitation on the invention and no such limitation in scope is to be.
