Vinyl chloride solubility in water.

Effects of water solubility of acrylonitrile on vinylidene chloride acrylonitrile styrene suspension polymerization. How can vinyl chloride affect my health. At 50 c the solubility of vinyl acetate in water is 0 1 wt more than at 20 c but the solubility of water in vinyl acetate doubles to about 2 wt. The us osha limits vinyl chloride exposure of workers to no more than 1 ppm for eight hours or 5 ppm for 15 minutes.

Volatilization is the most rapid process for removal of vinyl chloride introduced into surface waters. Water at 25 c 2 763 mg l epa 1985b 1 100 mg l cowfer and magistro 1983 organic solvent s soluble in hydrocarbons oil alcohol cowfer and magistro 1983. Water solubility is the upper limit on a chemical s dissolved concentration in pure water at a specified temperature. Drinking contaminated water also can expose you to vinyl chloride.

In the environment the highest levels of vinyl chloride are found in air around factories that produce vinyl products. The us epa and fda limit vinyl chloride in drinking water to 0 002 ppm. Water 3 4 ppm amoore and hautala 1983. Summary of chemical properties for vinyl chloride description symbolamean value coefficient of variation number of values.

Vinyl chloride is a chlorinated hydrocarbon occurring as a colorless highly flammable gas with a mild sweet odor that may emit toxic fumes of carbon dioxide carbon monoxide hydrogen chloride and phosgene when heated to decomposition. People may begin to taste vinyl chloride in water at 3 400 parts per billion ppb vinyl chloride is not easily absorbed by the skin. Half lives reported for volatilization from surface waters range from about 1 to 40 h ipcs 1999. At 20 c a saturated solution of vinyl acetate in water contains 2 0 2 4 wt vinyl acetate whereas a saturated solution of water in vinyl acetate contains 0 9 1 0 wt water.

Chemical and physical information. Food ingestion is a trivial source of exposure. If a water supply is contaminated vinyl chloride can enter household air when the water is used for showering cooking or laundry. Some data indicate that vinyl chloride is too readily volatilized to undergo bioaccumulation except perhaps in the most extreme exposure conditions.

Vinyl chloride has a relatively low solubility in water and a low capacity to adsorb to particulate matter and sediment.
