Since the chemical valence state of the key element tin in the product stannous octoate is bivalent, and belongs to the unstable intermediate valence state of tin, in the actual production process, the stannous octoate is extremely easy to generate oxidation reaction to generate stannous octoate possibly due to the existence of oxidizing agents (air, chlorine, sulfuric acid and the like), wherein the bivalent tin is oxidized to the tetravalent metal valence state, and although tetravalent tin compounds can be used as anti-aging agents, the foaming activity of the stannous octoate is greatly reduced by the substances, and the content of the stannous octoate is obviously reduced. In addition, in the production process of the product, due to the difference of chemical processes, in the process of synthesizing stannous octoate by taking stannous chloride as a raw material, unreacted metal simple substances also exist in the raw material stannous chloride, so that the content of the product is low.
