摘要:
A process is disclosed for the preparation of bis-(N-oxypyridyl-thio) derivatives of aluminum sulfonates by reacting a bis-isopropylate aluminum derivative of an organic sulfonate with two equivalents of the N-oxide of pyridine-2 thiol. The bis-isopropylate aluminum derivative of the organic sulfonate is formed by reacting the organic sulfonic acid precursor with aluminum isopropylate.
