Abstract: The process disclosed herein is method of recovering aluminum from multilayered packaging. The process comprises subjecting multilayered packaging to a reactor with aqueous formic acid, wherein the solution is sonicated using sonic horns. This process allows the recovery of aluminum in its pure metal form. PP/PE components of the multilayered packaging are recovered utilizing density separation, while ink and PET components require further treatment in a toluene reactor which may include sonication.

Abstract: The present invention includes a method of preparing a composition comprising (+)-doxapram or a salt thereof, wherein the composition is essentially free of (?)-doxapram or a salt thereof.

Abstract: The present disclosure relates to methods for preparing compounds, which are useful for regulating the expression of apolipoprotein A-I (ApoA-I), and in the treatment and prevention of cardiovascular disease and related disease states, including cholesterol- or lipid-related disorders, such as, for example, atherosclerosis.

Abstract: A process for the separation of a polyol or multiple polyols in admixture with other organic compounds, usually those produced with the polyol, is described. The process uses a distillation in a column (11) of a cyclic acetal from an aqueous solution which acetal is formed in a reaction mixture of the polyol and an aldehyde or ketone. The polyols, such as ethylene glycol and propylene glycol, are staple articles of commerce with many uses.

Abstract: The present invention provides a process for preparation of low molecular weight polyols from high molecular weight polyols in a hydrogenolysis reaction under elevated temperature and hydrogen pressure. The process comprises providing in a reaction mixture the polyols, a base, and a metal catalyst prepared by depositing a transition metal salt on an inert support, reducing the metal salt to the metal with hydrogen, and passivating the metal with oxygen, and wherein the catalyst is reduced with hydrogen prior to the reaction. In particular, the process provides for the preparation of glycerol, propylene glycol, and ethylene glycol from sugar alcohols such as sorbitol or xylitol. In a preferred process, the metal catalyst comprises ruthenium which is deposited on an alumina, titania, or carbon support, and the dispersion of the ruthenium on the support increases during the hydrogenolysis reaction.
