Procedure
3.96 g of tri-isobutyl aluminum were dissolved in 100 ml of benzene, and the solution was maintained at 15° C. under nitrogen gas current by ice cooling. A solution of 8.28 g of salicylic acid dissolved in 100 ml of tetrahydrofuran was added dropwise little by little to the above benzene solution. After completion of the dropwise addition, the reaction was further carried out for 2 hours at room temperature under agitation. After completion of the reaction, the solvent was distilled off under reduced pressure to yield 7.5 g of aluminum tris-(o-hydroxybenzoate) in the form of a white powder having a melting point above 300° C. The resulting aluminum salt had a molecular weight of about 530, and the average degree of polymerization was found to be about 1.2. The infrared absorption spectrum of the salt is as follows:
