Abstract: The present invention is a process for the production of isophorone having improved color and color stability. Crude isophorone is selectively hydrogenated to remove color forming impurities. The product isophorone will have an APHA color of about 10 or less.

Abstract: The present invention is one-step method for synthesizing a synthetic anion intercalated hydrotalcite material. The method comprises reacting an aluminum source with a magnesium source in the presence of an inorganic acid of the anion to be intercalated, and in the absence of a Group IA metal source. The resulting slurry can be dried to form the final product.
