Abstract
This method is used for purifying /met/acrylates, which are used in the production of construction polymers, intended for use in optical, optico-electronical and light-conducting equipment. It ensures purity of the target product between 99.99 and 99.999%, by operating in simple technological conditions.Description : /met/acrylates, with a formula CH=C/R1/-COOR2, are purified (where R1 is H or CH3, R2 is C1-3 alkyl radical), with a filling column, and the filling is zeolite, arranged from bottom to up along the height of the column in four layers with the size of the pores, respectively 10, 5, 4 and 3 angstroms.
