  • Patent number: 8039658
    Abstract: A method of removing trace levels of arsenic-containing impurities from raw triethylphosphate (TEPO) is disclosed. The method uses adsorption, or adsorption followed by a flash distillation. The method comprises contacting raw triethylphosphate (TEPO) with an adsorbent which selectively adsorbs the arsenic-containing impurities in the raw triethylphosphate (TEPO). The adsorbent is a base promoted alumina containing adsorbent represented by a formula: ZxWy; where x is the weight percentage of Z in the adsorbent ranging from 30% to 99.999%; y is the weight percentage of W in the adsorbent, and x+y=100%; Z is selected from the group consisting of alumina (Al2O3), magnesium-alumina based layered double hydroxide (MgO—Al2O3), alumina-zeolite, and mixtures thereof; and W is selected from the group consisting of at least one basic metal oxide, at least one basic metal carbonate, and mixtures thereof.
