  • Patent number: 5633397
    Abstract: Solid N-phosphonomethylglycine or glyphosate acid in "wet cake" form is charged to a suitable mixer/reactor. A stoichiometric equivalent of anhydrous ammonia gas is fed to the mixer for direct reaction with the glyphosate acid as it is agitated within the mixer. A water Jacket containing circulating water or other suitable heat transfer facilitating means readily known to those in the art is adapted to the mixer and used to remove heat from the reactor produced by the exothermic reaction. The moisture content of the glyphosate wet cake, the design of the mixer including a preferred close tolerance relation between the inner walls of the reactor and its mixing impellers together with the relative location of the ammonia gas inlet in the mixer/reactor and maintenance of a reaction temperature of about 60.degree. C. or below are all important process variables.

  • Patent number: 5306840
    Abstract: A process for preparing pure L-alpha-Glycerylphosphoryl-D-Myoinositol and its salts consists of a) preparing the crude Na+ or K+ salt of L-.alpha.-Glycerylphosphoryl-D-Myoinositol, passing an aqueous solution of the salt through an acid resin in H form whereby ion exchange occurs and the acid L-.alpha.-Glycerylphosphoryl-D-Myoinositol is eluted by washing the resin with water. Then the aqueous solution is passed through a basic resin whereby the L-.alpha.-Glycerylphosphoryl-D-Myoinositol is adsorbed on the resin as the anion. The resin is eluted first with a dilute solution of formic, acetic or propionic acid and then eluted with a more concentrated solution of the same acid. The preparation of severals salts is also described.
