20090318735 | PREPARATION OF GLUTARALDEHYDE - Provided is a process for the preparation of glutaraldehyde. The process comprises reacting an alkoxydihydropyran with water in the presence of an acidic catalyst. The alcohol by-product distilled from the reaction mixture is subjected to a heterogeneous catalyst that is located external to the distillation column used for distilling the alcohol, thereby increasing glutaraldehyde yield and decreasing the level of alkoxydihydropyran contamination in the alcohol. | 12-24-2009 |
20100096326 | METHOD TO CONTROL REVERSE OSMOSIS MEMBRANE BIOFOULING IN MUNICIPAL WATER PRODUCTION - A method of treating water for municipal use comprises treating the feedwater stream on the feed side of a reverse osmosis membrane with a non-oxidizing, bromine-containing biocide in the substantial absence of a reducing agent, such that biofouling of the membrane is reduced or prevented, and measuring the produced water stream on the permeate side for the presence of bromine-containing compounds. Advantages may include preservation of the membrane, production of water that meets applicable regulations for safe drinking, and simplified processing without additional steps to remove the biocide or its degradation products from the produced water. | 04-22-2010 |
