    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:Al.sup.iv (Al.sub.12-x M.sub.x).sup.vi O.sub.4 (OH).sub.24.sup.a+where x is a number from 1 to 6; a depends on the selection of M and N; N is selected from Al.sup.3+, Si.sup.4+, Ga.sup.3+, Ge.sup.4+, As.sup.5+, P.sup.5+, Cr.sup.3+, Fe.sup.3+, V.sup.5+, Ru.sup.3+, Ru.sup.4+, N.sup.3+ ; and M is selected from a metal from Groups 5B, 6B, 7B and 8 of the 4th, 5th and 6th Periods of the Periodic Table of the Elements.

    Abstract: This present invention includes a composition of matter made up of a kandite clay which has been treated with large molecules containing multi-atom metallic or semi-metallic species and heated to produce pillars within the clay which are located generally between the clay's layers. The pillared kandite composition is useful as a catalyst support, sorbent, or ion exchanger.The present invention also includes a process for producing the pillared kandite composition comprises mixing the finely divided clay in an aqueous solution with the pillaring medium and heating the resulting composition at a temperature high enough to decompose the added compound.

    Abstract: This invention is a composition of matter made up of an expanded smectite clay having multimetallic pillars separating the clay layers. The expanded clay may be used as a shape selective catalyst, catalyst support, or as an adsorbent material. More particularly, this invention relates to expanded smectite clays wherein the pillars are made up of aluminum and one or more transition metals.
