ABSTRACT:
A method for preparing unsymmetrical dialkyl ethers and derivatives thereof. The ethers are prepared by reacting a C.sub.1 to C.sub.3 aliphatic alcohol with a tertiary alcohol in the presence of a novel catalyst comprised of a transition metal pillared interlayered clay having generally separated layers wherein the interlayer distances are substantially greater than a precursor of the same but non-separated clay and wherein the product includes multimetallic pillars comprised of a cationic polymeric complex of the formula:
