Abstract: The present invention relates to azeotropic blends and pseudoazeotropic blends and to coating compositions including such blends. In one aspect, an azeotropic blend or a pseudoazeotropic blend consists essentially of octamethyltrisiloxane and a second component selected from the following: amyl acetate, 2-propoxyethanol, 1-methoxy-2-propylacetate, and 1-propoxy-2-propanol.

Abstract: A method for extracting water from an aqueous solution of a protein comprising the steps of: (a) intermixing the aqueous solution of the protein with a sufficient quantity of at least one glycol ether at a temperature at least 30 centigrade degrees above the lower critical solution temperature (LCST), preferably at least 20 centigrade degrees above the LCST, and most preferably at least 10 degrees above the LCST, to form a suspension comprising a concentrated aqueous protein phase and a liquid organic phase comprising said at least one glycol ether and at least 10 percent water extracted from the aqueous solution of the protein, wherein the glycol ether has an inverse solubility in water, with the proviso that the solubility of the glycol ether in water is significantly less than the solubility of water in the glycol ether, and the glycol ether does not significantly deactivate the protein, and (b) separating the concentrated aqueous protein phase formed in step (a) from at least a portion of the liquid organ

Abstract: A method for a liquid-liquid extraction of hydrophilic organic compounds from aqueous solutions thereof is described. The method generally includes intermixing a sufficient quantity of a specified glycol ether with the aqueous liquor at a first temperature to form a suspension comprising an aqueous raffinate phase and a glycol ether extract phase; separating the glycol ether extract phase from the aqueous raffinate phase; heating the glycol ether extract phase to a second, higher temperature to form a suspension comprising an aqueous extract phase containing a portion of the hydrophilic organic compound and a glycol ether raffinate phase; and separating this glycol ether raffinate phase from the aqueous extract phase. The selected glycol ether has an inverse solubility in water and the partition ratio, value K, for the hydrophilic organic compound is greater than 0.1.

Abstract: Glycol ether acetates, and in particular propylene glycol alkyl (or aryl) ether acetates, can be resolved enzymatically by enantioselective hydrolysis with a hydrolase at high concentrations of substrates; in some embodiments, the hydrolase is a lipase. Glycol ethers, and in particular propylene glycol alkyl (or aryl) ethers, can be resolved enzymatically by enantioselective transesterification with a hydrolase, in the presence of an acyl donor, at high concentrations of substrates; in some embodiments, the hydrolase is a lipase.
