N2 - The heats of adsorption of MeCN on metal substituted AlPO4-5 and AlPO4-11 compared to the pure AlPO's indicate the formation of strong acidic sites. Besides these strong sites some weaker acidic centers, probably P-OH groups were found. Accordingly, IR measurements on the loaded MeAPO's show some weakly Broensted bonded MeCN in combination with a strong Lewis complex. The Lewis bonded MeCN in the MeAPO's originate from coordinative interaction of the lone pair with the bivalent framework metal ions such as Mg2+, Mn2+, Co2+ or Zn2+. [on SciFinder (R)]
