Aluminum acetates
Aluminum acetate are the aluminum - salts of acetic acid , which are present as colorless solids and according to their three derivatives are distinguished:
- the neutral aluminum triacetate, Al (OOCCH 3 ) 3
- the basic aluminum diacetate , HOAl (OOCCH 3 ) 2 and
- the basic aluminum monoacetate , (HO) 2 AlOOCCH 3
Essentially, only aluminum diacetate , which is also known as acetic acid clay , is of practical significance . It is used in folk medicine and for the water-repellent impregnation of cotton fabrics.
synthesis
If aluminum sulfate is brought into a barium acetate solution, the triacetate is obtained. Another possibility for presentation is by combining aluminum hydroxide , acetic anhydride and glacial acetic acid in an aqueous solution, whereby the basic aluminum acetates are initially formed. The diacetate can be prepared directly by reacting sodium aluminate with acetic acid.
