Abstract: Disclosed herein are aqueous compositions comprising fructose and methods of production thereof. A method for producing an aqueous composition comprising fructose can comprise, for example, conducting an enzymatic reaction by contacting water, sucrose, and a glucosyltransferase enzyme that synthesizes poly alpha-1,3-glucan having at least 30% alpha-1,3-linkages. A soluble fraction produced by such a reaction comprises at least about 55% fructose on a dry weight basis, and can be separated from insoluble poly alpha-1,3-glucan product(s), thereby providing an aqueous composition comprising fructose.

Abstract: The present invention provides a process for separating iodine from a NaCl brine, comprising the following steps: (a) providing said NaCl brine containing iodide, (b) adjusting the pH of said NaCl brine to be no greater than 1.5, (c) adding oxidizing agent, such as chlorine containing oxidizing agent, to said NaCl brine resulting from step (b) to obtain an oxidation-reduction potential in said NaCl brine of from 560 mV to 925 mV, the combination of said pH of no greater than 1.5 and oxidation-reduction potential of 560 mV to 925 mV resulting in the formation of an iodine-chlorine anionic complex, and (d) contacting nonionic adsorption resin and said NaCl brine from step (c) one with the other to adsorb said iodine from this brine, to obtain as a result thereof NaCl brine wherein the iodine content therein is preferably no greater than 100 ppbw, more preferably no greater than 10 ppbw.

Abstract: A process for reducing fluorosurfactant content of a stabilized fluorosurfactant-containing aqueous fluoropolymer dispersion comprising contacting the stabilized fluorosurfactant-containing aqueous fluoropolymer dispersion with an anion exchange resin comprising a polymer and quaternary ammonium functional groups to reduce fluorosurfactant content, the functional groups being resistant to degradation which releases trialkylamines. The anion exchange resin is separated from the dispersion after the fluorosurfactant content has been reduced.

Abstract: The invention is a process for the purification of ethanol. In one embodiment the process includes boiling a degassed beer feed (106) in a pre-boiler (110) to provide a vapor by-pass fraction (112) that by-passes the conventional beer column and is fed into the rectifier column (124). The process allows free capacity in the rectifier column of new or established plants to be filled by ethanol-water vapor and/or condensate streams that do not originate from the beer column.
