    摘要: A method of removing a fermentation inhibitor from an aqueous mixture of hydrolysis products from cellulosic biomass is disclosed. The method includes providing an aqueous mixture of hydrolysis products from cellulosic biomass, the hydrolysis products comprising at least one of pentose or hexose sugars and a fermentation inhibitor that inhibits a microorganism otherwise capable of fermenting pentose or hexose sugars; and at least partially extracting the fermentation inhibitor from the aqueous mixture with a first extractant by a first liquid-liquid extraction through a first porous membrane to provide a first extract and a raffmate, the first extractant having a water solubility of less than one percent by weight. In some embodiments, the aqueous mixture contains an insufficient amount of the microorganism to ferment the aqueous mixture. In some embodiments, the aqueous mixture is a fermentation broth. A membrane solvent extraction system for carrying out the method is also disclosed.

    摘要: This disclosure relates to flame retardants that are useful for epoxy resin systems. Coating compositions and methods are provided the include an epoxy resin and a phosphate-containing flame retardant wherein the phosphate-containing flame retardant is selected from Group 1 metallic salts of a phosphate of a saccharide, Group 2 salts of a glycerophosphate, and Group 1 metallic salts of a polyphosphate. The provided flame retardants have low toxicity and are friendly to the environment.
