Abstract

Polyethylene glycol was found to undergo anionic 'catalyst poisoning' by lipophilic anions in a manner similar to that of quaternary ammonium salts, even though the interaction between alkali salts and the catalyst is generally considered to be influenced only by the cation. From reaction profiles which indicated catalyst poisoning, an exact kinetic equation describing the conversion as a function of time could be used to compute selectivity constants, Ks, by graphic iterations.
