N2 - Pervaporation enrichment of chlorine containing organic hydrocarbons from dilute aqueous solution through poly (acrylate-co-acrylic acid) composite membranes with crosslinked structure was investigated. Five copolymers were synthesized and their membranes were prepared on a porous poly (propylene) sheet. These membranes have selectivity in favor of halogen containing hydrocarbons in addition to permeability, depending on side chains. The following acrylate monomers were used: butyl acrylate (BA), (ert-butyl acrylate (tert-BA), lauryl methacrylate (LaMA), benzyl acrylate (BeA), cyclohexyl acrylate (CHA). Ratio of the acrylate monomer and acrylic acid was mostly 8.5/1.5 and 8.2/1.8. During the preparation of the membrane, crosslinking structure was introduced with ŅŅŅŅ-tetra glycidyl metaxylenediamine (TGXDA). Pervaporation was carried out for aqueous solutions of 1,1,2-trichloroethane (TCE), trichloro-ethylene and tetrachloroethylene using the copolymer membranes. Separation factor 500 of TCE/water and flux 24g/m2. hr were obtained at 25 C, about 0.2wt.% aqueous feed composition for copoly (BA-acrylic acid) membrane.
