Production Of N,N-Dialklylaminoethyl (Meth)Acrylates

US Patent:
7829738, Nov 9, 2010
Filed:
May 19, 2009
Appl. No.:
12/468585
Inventors:
Barbara E. Fair - Lisle IL, US
Cheng-Sung Huang - Naperville IL, US
Linh Quach - Arlington Heights IL, US
Peter E. Reed - Plainfield IL, US
Leonard M. Ver Vers - Downers Grove IL, US
Assignee:
Nalco Company - Naperville IL
International Classification:
C07C 69/52
US Classification:
560222
Abstract:
A method and apparatus for preparing a N,N-dialkylaminoalkyl acrylate 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.

Continuous Production Of Dmaea Quaternary Salts

US Patent:
8247597, Aug 21, 2012
Filed:
Jan 21, 2010
Appl. No.:
12/691159
Inventors:
Barbara E. Fair - Lisle IL, US
Peter E. Reed - Plainfield IL, US
Leonard M. Ver Vers - Downers Grove IL, US
Charles J. Holada - LaGrange Park IL, US
Cheng-Sung Huang - Naperville IL, US
Kailas B. Sawant - Aurora IL, US
Assignee:
Nalco Company - Naperville IL
International Classification:
C07C 69/52
US Classification:
560222
Abstract:
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.

Stabilization Of Manganese In Aqueous Systems

US Patent:
4963267, Oct 16, 1990
Filed:
Mar 26, 1990
Appl. No.:
7/501438
Inventors:
John E. Hoots - St. Charles IL
Kenneth P. Fivizzani - Naperville IL
Barbara E. Fair - Downers Grove IL
Assignee:
Nalco Chemical Company - Naperville IL
International Classification:
C02F 512
US Classification:
210701
Abstract:
The precipitate species of manganese in the presence of an oxidative condition in the waters of an aqueous system can be diminished by treating such waters with certain amide-containing polymer.

US Patent:
5023000, Jun 11, 1991
Filed:
May 10, 1990
Appl. No.:
7/521627
Inventors:
James F. Kneller - LaGrange Park IL
Barbara E. Fair - Downers Grove IL
Gianfranco F. Mazzani - Roma, IT
I. Sergio Di Simone - Roma, IT
Assignee:
Nalco Chemical Company - Naperville IL
International Classification:
C02F 514
US Classification:
210697
Abstract:
Calcium carbonate scale is controlled by treating calcium carbonate containing waters with a predominantly phosphinate containing composition where has as its major ingredient more than 32 mole percent of a phosphinicosuccinic acid oligomer having the probable structural formula. ##STR1## M is H, Na, K, NH. sub. 4, or mixtures thereof; and m and n are either 0 or a small whole number with proviso that either m or n is a small whole number and the sum of m plus n is greater than 2.
