Sulfanilic acid → HCID 131733075, compound

Participants

Reaction Steps

The powder prepared by Example 1 was calcined at 600° C. for 24 hrs in a high-temperature oven to form magnesium aluminum layered double oxide (LDO). Next, 30.06 g (1.5 times of the AEC of the magnesium aluminum layered double hydroxide) of sulfanilic acid salt (SAS) as a modifier was dissolved in 50 ml of water to form a modifier aqueous solution. 10 g of magnesium aluminum layered double oxide was then slowly added to the modifier aqueous solution and then the modifier aqueous solution was placed in a high-pressure autoclave to react at 100° C. overnight with agitation to form a mixture. The mixture was then washed with deionized water. After centrifugation for several times, the mixture was completely dried in a freeze-drying machine. The dried mixture was then milled to form magnesium aluminum sulfanilic acid salt (Mg—Al-SAS) layered double hydroxide powder. The XRD diffraction thereof is shown in FIG. 1.
