Vinyl Chloride Solubility In Water

The us osha limits vinyl chloride exposure of workers to no more than 1 ppm for eight hours or 5 ppm for 15 minutes.

Vinyl chloride solubility in water.

Drinking contaminated water also can expose you to vinyl chloride. Summary of chemical properties for vinyl chloride description symbolamean value coefficient of variation number of values. 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. Water solubility is the upper limit on a chemical s dissolved concentration in pure water at a specified temperature.

Vinyl chloride is primarily used to make polyvinyl chloride to manufacture plastics. 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. Shu xue zhou zhi xue weng zhi ming huang zu ren pan. Vinyl chloride 159 4.

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. Half lives reported for volatilization from surface waters range from about 1 to 40 h ipcs 1999. 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. 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. 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. Water 3 4 ppm amoore and hautala 1983. Volatilization is the most rapid process for removal of vinyl chloride introduced into surface waters. 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.

Based on a reported water solubility of 2 700 mg l a bcf of 7 was estimated indicating that vinyl chloride will not be expected to significantly bioconcentrate in aquatic organisms.
