International Classification:
C11D 754
US Classification:
252 99
Abstract:
A machine dishwashing composition is provided which comprises the following: (a) from 5 to 90 percent by weight of a compound corresponding to the formula ##STR1## wherein M is alkali metal or ammonium and wherein n is a number from 1 through 3, and wherein R is selected from an alkyl radical having from 1 to 20 carbon atoms, an alkenyl radical having from 1 to 20 carbon atoms, an alkynyl radical having from 1 to 20 carbon atoms, a cycloalkane radical having from 3 to 20 carbon atoms, an alkanol radical having from 2 to 20 carbon atoms, an ether radical having at least 3 carbon atoms, an aryl radical having at least 6 carbon atoms, a substituted aryl radical having at least 6 carbon atoms wherein the substituents are halogen, nitro, amide or carboxyalkyl substituents, aralkyl radicals having at least 7 carbon atoms and arylether radicals having at least 7 carbon atoms, and (b) from 0 to 5 percent by weight of a low-foaming anionic or nonionic surfactant, (c) a chlorine-providing material in an amount sufficient to provide from 0. 5 percent to 2 percent by weight available chlorine, and (d) from 5 percent to 30 percent by weight soluble sodium silicate having an SiO. sub. 2 to Na. sub. 2 O mole ratio of from 1:1 to 3. 2:1.

US Patent:
41566874, May 29, 1979
Filed:
Jul 27, 1978
Appl. No.:
5/928332
Inventors:
Marvin M. Crutchfield - Creve Coeur MO
Kent P. Lannert - Freeburg IL
Assignee:
Monsanto Company - St. Louis MO
International Classification:
C07D30724
US Classification:
2603473
Abstract:
A compound of the formula ##STR1## wherein R' is lower alkyl is useful as an intermediate to prepare a compound of the formula ##STR2## wherein X is selected from the group consisting of: ##STR3## wherein R is selected from the group consisting of alkali metal, NH. sub. 4. sup. +, NH(CH. sub. 2 CH. sub. 2 OH). sub. 3. sup. +, and lower alkyl, branched or straight chain, with up to about C. sub. 20 in the chain. The esters can be converted to salts useful as detergent builders.

US Patent:
42283000, Oct 14, 1980
Filed:
May 15, 1972
Appl. No.:
5/253357
Inventors:
Kent P. Lannert - Freeburg IL
Assignee:
Monsanto Company - St. Louis MO
International Classification:
C07C 5922
US Classification:
560180
Abstract:

Two-Stage Crystallization Of Nitrilotriacetonitrile From A Hot Solution

View page
US Patent:
44850492, Nov 27, 1984
Filed:
Jan 3, 1983
Appl. No.:
6/455394
Inventors:
Kent P. Lannert - Freeburg IL
Chung Y. Shen - St. Louis MO
Dat S. Trieu - St. Louis MO
Assignee:
Monsanto Company - St. Louis MO
International Classification:
C07C12143
US Classification:
2604655R
Abstract:
A process is disclosed for producing crystalline nitrilotriacetonitrile from a solution of nitrilotriacetonitrile and water in excess of 95. degree. C. , comprising: a. cooling the nitrilotriacetonitrile-water solution in a first stage to the range of about 70. degree. C. to about 90. degree. C. , preferably from about 80. degree. C. to about 90. degree. C. , and more preferably about 85. degree. C. , to produce a nitrilotriacetonitrile water slurry; and b. further cooling the nitrilotriacetonitrile-water slurry in a second stage to below about 35. degree. C. , carried out either continuously or in a batch process. Cooling in the first stage is preferably accomplished by recycling cooled nitrilotriacetonitrile-water slurry from the second stage. Cooling in the second stage is preferably accomplished by vacuum cooling.
