Examples
Embodiment 1
[0024] Take 50g of the mixed product and 200g of sulfuric acid solution (wt%: 5%) for mixing and stirring. After stirring evenly, let it stand for stratification. The mass of the upper organic oil phase is 42g, and the lower aluminum-containing aqueous phase is 206g. The lower aqueous phase was concentrated by heating, and crystallized by cooling to obtain 32 g of solid aluminum sulfate.
Embodiment 2
[0026] Take 50g of the mixed product and 100g of sulfuric acid solution (wt%: 10%) for mixing and stirring. After stirring evenly, let it stand for stratification. The mass of the upper organic oil phase is 41g, and the lower layer contains aluminum-containing aqueous phase 108g. The lower aqueous phase was concentrated by heating, and crystallized by cooling to obtain 33 g of solid aluminum sulfate.
Embodiment 3
[0028] Take 50g of the mixed product and 75g of sulfuric acid solution (wt%: 15%) for mixing and stirring. After stirring evenly, let it stand for stratification. The mass of the upper organic oil phase is 42g, and the lower aluminum-containing aqueous phase is 81g. The lower aqueous phase was concentrated by heating and crystallized by cooling to obtain 31 g of solid aluminum sulfate.
