Recovery Of Phosphorus Values And Salt Impurities From Aqueous Waste Streams

US Patent:
2012010, Apr 26, 2012
Filed:
May 13, 2010
Appl. No.:
13/319811
Inventors:
Chil Y. Choi - Chesterfield MO, US
Gregory A. Hartmann - Kirkwood MO, US
Peng Lei - St. Louis MO, US
Fuchen Liu - Ballwin MO, US
William Poncez - Kirkwood MO, US
Peter E. Rogers - Des Peres MO, US
William A. Scholle - Webster Groves MO, US
Lowell Smith - Kirkwood MO, US
Robert B. Weisenfeld - Chesterfield MO, US
Assignee:
MONSANTO TECHNOLOGY LLC - St. Louis MO
International Classification:
C01D 3/04
C07F 9/38
US Classification:
423181, 423184, 423207, 423204, 562 17
Abstract:
The present invention generally relates to processes for recovery of phosphorus values and salt impurities from aqueous waste streams. In particular, the present invention relates to processes for recovery of phosphorus values and salt impurities from aqueous waste streams generated in the manufacture of phospho-herbicides, including N-(phosphonomethyl)glycine and glufosinate.

Process For Purifying N-Phosphonomethylglycine

US Patent:
5087740, Feb 11, 1992
Filed:
Jul 30, 1990
Appl. No.:
7/561483
Inventors:
Lowell R. Smith - Kirkwood MO
Assignee:
Monsanto Company - St. Louis MO
International Classification:
C07F 938
US Classification:
562 17
Abstract:
N-Phosphonomethylglycine can be purified and concentrated from aqueous solutions containing N-phosphonomethylglycine and impurities, such as N-formyl-N-phosphonomethylglycine, phosphorous acid, and the like, by passing the aqueous solution through an ion exchange column containing a weakly basic ion exchange resin to remove such impurities.

Process For The Preparation Of Glyphosate And Glyphosate Derivatives

US Patent:
5578190, Nov 26, 1996
Filed:
Apr 7, 1995
Appl. No.:
8/418717
Inventors:
Thomas E. Rogers - Manchester MO
Lowell R. Smith - Kirkwood MO
Assignee:
Monsanto Company - St. Louis MO
International Classification:
C07F 938
C07F 940
C25B 300
US Classification:
205436
Abstract:
A process for preparing glyphosate and other secondary amines of related structure in which a precursor primary amine such as aminomethylphosphonic acid is condensed with glyoxylic acid, or a related aldehyde compound, and the condensation product reduced without isolation to produce the desired product.

Use Of Monosodium Iminodiacetic Acid Solutions In The Preparation Of N-Phosphonomethyliminodiacetic Acid

US Patent:
5986128, Nov 16, 1999
Filed:
Nov 1, 1996
Appl. No.:
8/742523
Inventors:
Lowell Richard Smith - Kirkwood MO
Assignee:
Monsanto Company - St. Louis MO
International Classification:
C07F 938
C07C22924
US Classification:
562 17
Abstract:
A method is described for making solution stable salts of iminodiacetic acid (IDA), useful as precursors in the manufacture of N-phosphonomethylglycine. Concentrated dialkali salts of IDA which are insoluble at temperatures below about 55. degree. C. , such as the disodium salt (DSIDA) are acidified to monoalkali salts, such as monosodium IDA (MSIDA). The resulting salts are stable in solution, and may conveniently be stored or transported in solution without recourse to dilution, heating, or similar measures.

Process For The Preparation Of Glyphosate And Glyphosate Derivatives

US Patent:
5874612, Feb 23, 1999
Filed:
Feb 5, 1990
Appl. No.:
7/474309
Inventors:

Thomas E. Rogers - Manchester MO
Lowell R. Smith - Kirkwood MO
International Classification:
C07F 938
US Classification:
562 17
Abstract:
A process for preparing glyphosate and other secondary amines of related structure in which a precursor primary amine such as aminomethylphosphonic acid is condensed with glyoxylic acid, or a related aldehyde compound, and the condensation product reduced without isolation to produce the desired product.

Process For Producing N-Phosphonomethyl Glycine

US Patent:
4002672, Jan 11, 1977
Filed:
Mar 22, 1972
Appl. No.:
5/236769
Inventors:
Lowell R. Smith - Chesterfield MO
Assignee:
Monsanto Company - St. Louis MO
International Classification:
C07F 938
US Classification:
2605025
Abstract:
N-phosphonomethyl glycine is produced by the strong acid catalyzed hydrolysis of N-(phosphonomethyl) imino-diacetic acid. N-phosphonomethyl glycine is useful as a post-emergent herbicide.
