Abstract: There is disclosed a composition comprising an alloy represented by the following generic formula Aa)n(Bb)n(Cc)n(Dd)n(ee)n( . . . )n; wherein A is an oxygen storage agent; B is an anti-sintering agent; C is an oxidation catalyst; D is a reduction catalyst; and E is a NOx absorbing agent; wherein each subscript letter represents compositional stoichiometry; wherein n is greater than or equal to zero; wherein the sum of the n's is equal to or greater than 2, and wherein the alloy comprises at least two different metals. There is also disclosed a washcoat composition; a catalyst support; methods of making the alloy, the washcoat composition, and the catalyst support.

Abstract: Dodecene-1 and 1-tetradecene can be rectified from a mixture containing 1-dodecene and 1-tetradecene and triethylaluminum ("TEA") which has about the same normal boiling point as 1-dodecene and 1-tetradecene by feeding the above mixture to an intermediate point of a rectification column maintained under sufficient vacuum (e.g. 5-30 torr) such that the temperature at the intermediate feed point is about 250.degree.-260.degree. F. and the overhead distillation temperature is about 190.degree.-240.degree. F. The TEA which normally boils at about the same temperature as 1-dodecene and 1-tetradecene will exist as a dimer permitting part of the 1-dodecene and 1-tetradecene to distill overhead and most of the TEA to exit the bottom of the column.
