Abstract: Methods and compositions for improving performance of flocculants in an industrial production process. Methods include pH triggered cross-linking reaction between a flocculating agent, such as dextran, and a composition comprising a boronic acid-containing polymer. The pH trigger can be provided by a fluid having a pH of 8 or more. The production process can be a Bayer Process and the fluid is caustic liquor or slurry in the fluid circuit of the Bayer, wherein the reaction time is reduced over conventional methods and the cross-linked dextran composition effectuates improved flocculation of the trihydrate particles.

Abstract: Alkaline spray-on cleaners that can be delivered by pump or pressurized gas aerosol spray have been made with reduced choking mists are disclosed. The cleaning composition comprises the use of anti-mist components consisting of large anionic copolymer comprised of acrylamide and AMPS (acrylamide-sodium 2-acrylamido-2-methylpropane sulfonate), and polyethylene oxide polymers that create non-Newtonian solutions. The composition also includes a surfactant, and a source of alkalinity.
Abstract translation: 通过泵或加压气雾剂喷雾可以输送的碱性喷雾清洁剂已经被制成，减少了窒息雾。 清洁组合物包括使用由丙烯酰胺和AMPS（丙烯酰胺 - 2-丙烯酰胺基-2-甲基丙烷磺酸钠）组成的大型阴离子共聚物和产生非牛顿溶液的聚环氧乙烷聚合物组成的防雾组分。 该组合物还包括表面活性剂和碱度源。
