PHYSICAL REUTILIZATION OF SILICONIZED SHEETS

The method for the physical reutilization of sheet-like siliconized structures comprises treating the sheet-like siliconized structure in a liquid digestion system comprising acetic anhydride and/or an acetoxysiloxane, and at least one Brøonsted acid, optionally solvent, preferably with addition of acetic acid, and removing the desiliconized sheet-like structure from the liquid phase.

Salts of diaminoacetals and diaminoketals and their synthesis, and their transformations to diaminoacetals and diaminoketals

This application relates, in part, to novel salts represented by the following structure of Formula (1): ##STR00001##
wherein R.sup.1a is selected from the group consisting of hydrogen and optionally substituted alkyl (e.g., unsubstituted C.sub.1-6 alkyl, e.g., —CH.sub.3); R.sup.1b is optionally substituted alkyl (e.g., unsubstituted C.sub.1-6 alkyl, e.g., —CH.sub.3); each occurrence of R.sup.2 and R.sup.3 is independently selected from the group consisting of hydrogen, optionally substituted alkyl, optionally substituted cycloalkyl, and optionally substituted aryl; R.sup.2 and R.sup.3 can combine with each other to form optionally substituted cycloalkyl; each m and n is independently an integer ranging from 1 to 20 (e.g., m and n is independently an integer ranging from 1 to 5); and each of Q.sup.1.sup. and Q.sup.2.sup.is independently a counterion (e.g., each of Q.sup.1.sup.and Q.sup.2.sup. is independently a counterion selected from the group consisting of chloride, bromide, fluoride, iodide, acetate, carboxylate, hydrogen sulfate, nitrate, and phenolate, and sulfonate, e.g., chloride), and methods of making the same.

Method for Recovering Aluminum from Multilayered Packaging Utilizing Sonication and Formic Acid

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.
