Product Safety Assessment METATIN Catalyst S-26 (Stannous

ProcessStannous octoate is produced by dissolving tin metal in hydrochloric acid (HCl) to generate liquid stannous chloride (SnCl2). Stannous chloride is then reacted with sodium hydroxide (NaOH) and the resulting SnO is reacted further with 2-ethylhexanoic acid forming stannous octoate as the final product. The structure is shown below. C

How to Estimate the Tin Content Assay Determination

Zinc reduces tin chloride to the metallic state and it can then be filtered off and re-dissolved in strong HCl. Experiments showed that whilst being re-dissolved there was a tendency for the tin to oxidize to stannic chloride and in this method one is obliged to assume that the tin dissolves wholly as stannous chloride.

Assaying Tin OreMineral Processing Metallurgy

Tin in solution as stannic or stannous chloride is precipitated as metal by means of zinc. The fact that tin forms two well-defined series of compounds is taken advantage of in assaying (just as in the case of iron) by determining how much of an oxidising agent is required to convert it from the stannous
