The Uses of Stannous chloride dihydrate
Powerful reducing agent, particularly in manufacture of dyes and 99mTc radiopharmaceuticals; in tinning by galvanic methods; in liquor finishing of wire; in sensitizing of glass and plastics before metallizing; as soldering flux; as mordant in dyeing with cochineal; in manufacture of tin chemicals, color pigments, pharmaceuticals, sensitized paper, lubricating oil additives; as tanning agent; in removing ink stains; in yeast revivers; as reagent in analytical chemistry; as catalyst in organic reactions.
The Uses of Stannous chloride dihydrate
To a solution of the SM (10.9 g, 27.7 mmol) in EtOAc (100 mL) was added SnCl2-2H2O (18.7 g, 83.1 mmol). The reaction mixture was stirred at 50 C overnight. The mixture was filtered through celite, and the filtrate was washed with 10% NaHCO3. The layers were separated and the aq layer was further extracted with EtOAc. The combined organics were dried and concentrated in vacuo to provide the product as a brown solid. [9.5 g, 95%]
The Uses of Stannous chloride dihydrate
Stannous chloride is used as a sensitizing agent in preparing glass and plastic for metalizing. It serves as a potent reducing agent. Other uses of stannous chloride are tin electroplating baths, corrosion inhibitors, polymers, thermoplastic elastomers, soldering flux, antioxidant, tanning agent and pharmaceuticals.
The Uses of Stannous chloride dihydrate
Tin(II) chloride dehydrate may be used:
- As a reducing agent for the determination of hydride forming species by AAS.
- In the conversion of organomercurials into inorganic mercury determined using a flow injection-cold vapor atomic absorption spectrometry
- In the determination of total mercury content, using atomic fluorescence spectroscopy and mercury speciation was performed using gas chromatography inductively coupled plasma mass spectrometry (GC-ICPMS).
