  • Patent number: 8308840
    Abstract: A continuous method and a production device for producing hydrolysis-resistant stable ionic titanium (Ti4+) are provided. The method comprises six steps: (i) carrying out a redox reaction between metal titanium and excess strong acid; (ii) carrying out primary chelation; (iii) diluting; (iv) adjusting pH value for the first time; (v) carrying out secondary chelation; and (vi) adding microelement and adjusting pH value for a second time. The device includes a reaction kettle, multiple metering pumps, a chelation kettle, dilution tank, multiple precise mixing reaction kettles, a first chelator storage tank, a pure water storage tank, an alkali liquor storage tank, a second chelator storage tank, multiple microelements storage tanks, a control center, etc. The method uses a multi-point, spiral, reverse and atomization spraying technique synchronously to carry out digital fully automatic continuous production and reach the effect of elaborately mixing the material.
