dc.description.abstractDevelopment of active and selective catalyst for the process of obtaining methacrylate monomers from methyl propionate, propionic acid and formaldehyde is one of important stages to industrial implementation of this process. In order to solve this problem, we designed catalyst based on oxides of boron and phosphorus that were promoted by mixture oxides of zirconium and tungsten. The total yield of the target products at optimum temperature of 593 K is 52.3 % with the total selectivity of their formation at 96.4 % and the conversion of reagents of 54.2 %. We determined the effect of adding methanol on the ratio of products MMA/MAA.uk_UA
