Process for preparing 2-hydroxyethyl methacrylic acid ester |
| abstract |
Process for preparing 2-hydroxyethyl ester of an acidnmethacrylic re-esterification with methyl ornmethacrylic acid ethyl esters with ethylene glycolnunder the catalytic action of alcoholnalkali metal or quaternary ammoniumnthe base of being a distillatenconsisting of methyl or ethyl alcoholnmixture with methyl methacrylate leads tonwith water in which the respective alcohol is separatednfrom the reaction component to water anunreacted methyl methacrylate is recycledninto the reactor. Boiling point of the reaction mixturencontrolled by the pressure maintained at the top of the columnnrespectively, in a capacitor. Listed backnThe production of HEMY is widely used innmedical prosthetics, as a body replacementntissues, to make contact lenses ornpreparation of copolymers for special lacquers. |
