    摘要: Methods of preparing stannous oxide including neutralizing a solution of divalent tin ions in a mineral acid using a weak base, followed by heating the neutralized solution optionally under an inert atmosphere are provided. The stannous oxide particles produced are readily soluble in alkyl sulfonic acids.

    摘要: Disclosed are processes for the selective extraction of tin from aqueous acidic solutions bearing tin and other metal cations. Branched tertiary phosphine oxides comprising at least two branches per alkyl group show higher extraction coefficients, E, for tin than other metals, e.g. zinc (III), iron (II), iron (III), copper (II) and lead (II). Novel compositions for selectively extracting tin comprising combinations of symmetrical branched phosphine oxides and unsymmetrical phosphine oxides are also disclosed.

    摘要: Disclosed is a method for preparing aqueous negatively charged tin oxide sols having substantially uniform particle size no greater than about 50 nm and preferably from about 5 to about 20 nm, the sols being characterized as being substantially free of any other reagents which may adversely affect contemplated usage as a catalyst.
