SCHIFF BASE BASED METAL COMPLEX COMPOUND AND OXYGEN ADSORBENT AND OXYGEN-SEPARATING MEMBRANE CONSISTING OF SAID COMPOUND

摘要

NEW MATERIAL:A compound expressed by formula I [rings A and B are O- phenylene having long-chain hydrocarbon group expressed by formula -X-CnHm (14<=n<=22; 21<=m<=45); X is -O-, -COO-, -NHCO- or -S-; R0 is -CH2CH2-, formula II, formula III or 1-6C hydrocarbon; M is Fe, Co, Ni, Mn, Cr or Zn]. EXAMPLE:Bis[2-hydroxy-4-octadecyl-oxy-benzal)ethylenediiminecobalt. USE:An oxygen adsorbent. PREPARATION:A metal ion selected from Fe, Co, Cu, Ni, Mn, Cr or Zn is feeded to a non circular multidentate coordination compound to form a chelate ring between metal ions.
