    摘要： Provided is a method for producing an aqueous zirconium chloride solution having a higher decomposition rate of zircon sand and a lower impurity content, as compared with conventional methods.
    The method for producing an aqueous zirconium chloride solution according to the present invention comprises:
    step 1 of grinding zircon sand to an average particle diameter of 10 µm or less;
    step 2 of adding a sodium compound to the ground zircon sand to thereby obtain a mixture;
    step 3 of firing the mixture in an iron container at 400°C or less to thereby obtain a decomposed product;
    step 4 of firing the decomposed product in a stainless-steel container at 400 to 1,100°C to thereby obtain a fired product;
    step 5 of dispersing the fired product in water to prepare a dispersion, and washing the fired product with water while adjusting the temperature of the dispersion to 70°C or less, thereby obtaining a water-washed cake;
    step 6 of washing the water-washed cake with hydrochloric acid with a pH of 1 to 6 to thereby obtain zirconium hydrate; and
    step 7 of dissolving the zirconium hydrate in hydrochloric acid, and then removing insoluble components to thereby obtain a salt solution.

    摘要： This invention relates to a method of forming activated antiperspirant salts, wherein the activated salts are formed by heating a solution of Z 2 (OH) 6-a X a , wherein Z is a member selected from the group consisting of aluminum, zirconium and mixtures thereof, a ranges from 0.3 to 4 and X is a member selected from the group consisting of Cl, Br, I and mixtures thereof, to a temperature from about 140° to about 200 °C. for a period of time ranging from one to five minutes or one to thirty minutes if a recycling loop heat exchanger is used and then drying said salt solution in its activated state. This process provides a much more rapid means of making activated antiperspirant salts, as it is taught in the art to heat the starting materials for periods up to thirty days.
