| titleOfInvention | High-concentration tin sulfonic acid aqueous solution and preparation method thereof |
| abstract | The high-concentration tin sulfonate aqueous solution of the present invention has a divalent tin ion (Sn 2 + ) concentration of 360 g/L to 420 g/L, a tetravalent tin ion (Sn 4 + ) concentration of 10 g/L or less, and free The resulting methanesulfonic acid concentration is 40 g/L or less, the hazen unit color number (APHA) is 240 or less, and the turbidity is 25 FTU or less. In this aqueous solution, stannous oxide powder adjusted to a temperature of 10 °C or less was added to an aqueous solution of methanesulfonic acid having a circulating concentration of 60% by mass to 90% by mass while maintained at a temperature of 10°C or less to obtain tin oxide powder. It is prepared by dissolving. |
