Specification

The Sulfur dioxide with CAS registry number of 7446-09-5 is also known as Sulphur dioxide. It belongs to product categories of Refrigerants; Inorganics; Chemical Synthesis; Compressed and Liquefied Gases; Synthetic Reagents; Compressed and Liquefied GasesMaterials Science; Alternative Energy; Electrolytes. This chemical is a colourless gas and should be stored in ventilated and dry place. Sulfur dioxide is the chemical compound with the formula SO2. It is a toxic gas with a pungent, irritating smell, that is released by volcanoes and in various industrial processes.

Physical properties about Sulfur dioxide are: (1)#H bond acceptors: 2; (2)Index of Refraction: 1.51; (3)Molar Refractivity: 12.053 cm3; (4)Molar Volume: 40.269 cm3; (5)Polarizability: 4.778 10-24cm3; (6)Surface Tension: 66.8939971923828 dyne/cm; (7)Density: 1.591 g/cm3; (8)Enthalpy of Vaporization: 24.94 kJ/mol; (9)Boiling Point: -10 °C at 760 mmHg; (10)Vapour Pressure: 2533.46899414063 mmHg at 25°C

Preparation of Sulfur dioxide: It is prepared by the combustion of hydrogen sulfide and organosulfur compounds.

2H2S+3O2→2H2O+2SO2

Uses of Sulfur dioxide: It is an intermediate in the production of sulfuric acid, being converted to sulfur trioxide and sometimes used as a preservative for dried apricots and other dried fruits. It is an important compound in winemaking, and is designated as parts per million in wine and also a good reductant. What's more, It or its conjugate base bisulfite is produced biologically as an intermediate in both sulfate-reducing organisms and in sulfur oxidizing bacteria as well. It is a candidate material for refrigerants and a versatile inert solvent that has been widely used for dissolving highly oxidizing salts. Treatment of aryl diazonium salts with sulfur dioxide and cuprous chloride affords the corresponding aryl sulfonyl chloride.

When you are using this chemical, please be cautious about it. As a chemical, it is toxic by inhalation and may cause burns. During using it, wear suitable protective clothing, gloves and eye/face protection. Keep container in a well-ventilated place. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. If accident happens or you feel unwell seek medical advice immediately.
