Description
Sulfur dioxide is a compound formed by the combination of the elements sulfur and oxygen. On a weight basis, the proportion of the elements is about I part sulfur to I part oxygen, or more exactly, 50.05 percent to 49.95 percent, respectively. At standard conditions of temperature and pressure, sulfur dioxide is a colorless gas with a characteristic pungent odor. It may be cooled and compressed to a colorless liquid, which, at one atmosphere pressure, boils at 14°F (10.0°C) and freezes at -104.6°F (-75.9°C). Sulfur dioxide liquid is heavier than water, and has a specific gravity of 1.436 at 32°F (0°C). As a gas, it is more than twice as heavy as air; its relative density is 2.2638 at atmospheric pressure and 32°F (0°C).Sulfur dioxide is not flammable or explosive in either the gaseous or liquid state. It is a relatively stable chemical. Temperatures above 3632°F (2000°C) are required to bring about detectable decomposition of sulfur dioxide. Dry sulfur dioxide (less than 100 ppm water) is not corrosive to ordinary metals. However, in the presence of even small amounts of water, sulfur dioxide becomes corrosive to most metals, with exceptions including lead, Type 316 stainless steel, and certain alloys. Glass and certain plastics are also resistant to moist sulfur dioxide.
