Abstract: The present invention relates to a method of recycling aluminum clad materials. In particular, the method relates to recycling clad materials such as brazing sheet comprised of two or more aluminum alloys, by selective melting of one of the alloys. The feedstock is agitated during heating to allow separation of the molten alloy from the unmelted core, and the molten alloy is removed, such as by draining off during the process.
Abstract: The invention includes a process for performing high performance liquid chromatography in the reverse phase. The present process for high performance separations by liquid chromatography uses a separations media, including separations packing materials for packed column separations, of polybutadiene coated and crosslinked on a surface of generally spherical metal oxide/hydroxide support particles comprising crystals of metal oxide/hydroxide with the crystals extending radially outward from a central core region and having a shape selected from principally acicular to principally lamellar. It has been found that liquid chromatography using the process of the present invention works particularly well in separating basic, nitrogen-containing compounds.
