Procedure

77 grams of triethanolamine (0.52 mole) is added to 200 grams of water with stirring, followed by the addition of 20 grams of an 85% solution of phosphoric acid (0.17 mole phosphoric acid), to form a solution of triethanolamine phosphate. 221 grams (0.76 mole) of antimony trioxide, 1201 grams of water, and 147 grams (1.51 moles) of hydrogen peroxide are heated at reflux for approximately 22 minutes. The triethanolamine phosphate solution from above is then charged to the reaction mixture. The product is a colloidal dispersion of hydrous antimony pentoxide particles in an essentially aqueous medium. The dispersion contains approximately 9% antimony, has an average particle size of less than 40 Å, and is stabilized with approximately 0.3 moles of the alkanolamine salt per mole of antimony.
