Abstract
1,240,798. Disodium nitrilotriacetate compositions. MONSANTO CO. 4 March, 1969 [4 March, 1968], No. 11488/69. Addition to 1,232,890. Heading C2C. [Also in Division C5] A water-soluble granular composition, suitable as a detergent additive, comprises 10- 87% by weight of disodium nitrilotriacetate, 0-88À5% by weight of trisodium nitrilotriacetate and 1À5-30% by weight of a soluble sodium salt of a second acid, the product having a bulk density of 0À4-0À8 g./c.c. and having greater than 50% of its particles larger than the openings in a U.S. Standard 80-mesh screen and smaller than a 4-mesh screen. The product is obtained by treating trisodium nitrilotriacetate with 10-100% of a molar equivalent of a waterdispersible acidic material in the presence of 5-25% by weight of water, based on the total reaction medium, agglomerating the mixture and drying to give the desired product. Suitable second acids are sulphuric, orthophosphoric, pyrophosphoric and condensed phosphoric acids or acidic Na or K salts of such acids, or mixtures thereof. The acid is preferably used as a 30- 75% by weight aqueous solution.
