The present invention relates, in part, to an improved process for oxidation of alcohols containing oxidatively sensitive functional groups, using inexpensive reagents under mild reaction conditions to provide high yields of carbonyl products such as aldehydes or ketones. In certain embodiments, an aldehyde product is obtained by contacting an oxidatively sensitive alcohol, such as an alkenol, with an oxidant and a TEMPO catalyst under conditions sufficient to convert the alkenol to the aldehyde.

The present invention provides a method of making a methylene malonate monomer that includes the steps of reacting a malonic acid ester with a source of formaldehyde optionally in the presence of an acidic or basic catalyst and optionally in the presence of an acidic or non-acidic solvent to form reaction complex. The reaction is optionally performed in the presence of or contacted with an energy transfer means such as a heat transfer agent, a heat transfer surface, a source of radiation or a laser such that reaction complex is substantially vaporized to produce a vapor phase comprising methylene malonate monomer which may be isolated. The present invention further provides methylene malonate monomers prepared by the method of the invention, as well as compositions and products formed from the methylene malonate monomers, including monomer-based products (e.g., inks, adhesives, coatings, sealants or reactive molding) and polymer-based products (e.g., fibers, films, sheets, medical polymers, composite polymers and surfactants).

The present invention provides counter flow cascade separation systems useful to separate solute/solute pairs present in a solvent. The separation systems include a series of interconnected stages with each stage comprising a diafilter preferentially permeable for one solute. Solute/solute pairs are preferentially separated by the diafilter into permeate and retentate flows. Stages are combined to form separation systems capable of operation approaching an ideal cascade.
