发明名称 A method for producing basic aluminium sulphate (III).
摘要 <p>The present invention relates to a method for producing sulphate-poor, polynucleate aluminium hydroxide sulphate complexes of the general formula &lt;Chemistry id="chema01" num="0001"&gt;&lt;Image id="ia01" he="7" wi="52" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /&gt;&lt;/Chemistry&gt;in which n is an integer; x is 0.75-2.0; y is 0.5-1.12; x + 2y is 3; z is 1.5-4 when the product in solid form, and z 4 when the product is in the form of an aqueous solution, an amorphous aluminium hydroxide being admixed with aluminium sulphate and/or sulphuric acid to y = 0.5-1.12; preferably 0.5-0.75.</p>
