| titleOfInvention | Method for Producing Highly Basic Aluminum Chloride Aqueous Solution Suitable for Alumina Powder Synthesis |
| abstract | 【Task】 By synthesizing a highly basic aluminum chloride aqueous solution having a low content of impurities Fe, Ca, Mg and Si and a basicity of 67 to 85%, it is possible to produce uncolored alumina powder by firing. Provided is a method for producing a highly basic aluminum chloride aqueous solution. SOLUTION: In the present invention, after mixing water, sodium aluminate and an aluminum sulfate solution, 15 to 20% by weight of Al and 0 to 0.2% by weight of sulfate ion concentration are contained in the aqueous solution in terms of Al 2 O 3 . A raw aluminum chloride aqueous solution having a basicity of 40 to 65% is added, and the reaction is carried out at 45 to 85 ° C. for 40 to 240 minutes, and then slowly cooled to a range of 40 to 65 ° C. over 7 to 18 hours. Provided is a method for producing a highly basic aluminum chloride aqueous solution having a basicity of 67 to 85%, which comprises 8 to 13% by weight of Al in terms of Al 2 O 3 .
