The amorphous salicylate‐bearing product precipitated when C 3 A and related compounds are placed in contact with salicylic acid in aqueous solution and the residual contents of the solutions were examined by ir spectroscopy. Comparison with spectra of several aluminosalicylate complexes and crystalline aluminosalicylic acid indicated that the amorphous product is a hydroxylated chelate complex designated as Al(sal)OH, precipitated over a period of time from the cationic aluminosalicylate complex Al(sal) + , which is formed rapidly in solution.
