Patent number: 8247597Abstract: The invention provides a method of continuously producing high quality quaternized N,N-dialkylaminoethyl (meth)acrylates (DMAEA.MCQ) that has a long shelf life and which is stable in water. The method involves placing starting materials into a continuously stirred tank reactor in the presence of less than 6% water. This low amount of water causes two liquid phases to form and prevents unwanted side reactions. The denser liquid phase contains DMAEA.MCQ and the lighter phase contains the starting materials. Liquid from the denser phase is removed from a position where little of the lighter phase has been mixed in. The removed liquid then has any last traces of the starting materials reacted into DMAEA.MCQ and strips away any starting materials with a gas flow. The resulting liquid is high purity DMAEA.MCQ. Water can then safely be added to ease in the transport and use of the produced DMAEA.MCQ.Type: GrantFiled: January 21, 2010Date of Patent: August 21, 2012Assignee: Nalco CompanyInventors: Barbara E. Fair, Peter E. Reed, Leonard M. Ver Vers, Larry E. Brammer, Jr., Charles J. Holada, Cheng-Sung Huang, Kailas B. Sawant

Publication number: 20100298594Abstract: A method and apparatus for preparing a N,N-dialkylaminoalkyl acrytate in a continuous transesterification reaction. The reaction involves adding alkyl acrylates such as methacrylate or ethacrylate to a reboiler mechanism and efficiently removing alcohol co-products. Because the reaction is continuous, the alkyl acrylates can be added as needed to increase output, decrease output, or fine-tune the reaction dynamics. An entrainer is used to form a volatile azeotrope which contains both alcohol and entrainer and which is easily removed from the reboiler mechanism. This method reduces the amount of entrainer needed per unit of alkyl acrylate used and eliminates any need to purify the end product from entrainer contamination of the resulting N,N-dialkylaminoalkyl acrylate product.Type: ApplicationFiled: May 19, 2009Publication date: November 25, 2010Inventors: Larry E. Brammer, JR., Barbara E. Fair, Cheng-Sung Huang, Linh Quach, Peter E. Reed, Leonard M. Ver Vers
