Vinyl Chloride Vapor Pressure At 25 C

Vapors are heavier than air.

Vinyl chloride vapor pressure at 25 c.

Approximate vapor pressure for temperatures in the range 20 o c 25 o c 68 o f 77 o f. Shipped as a liquefied compressed gas. Details of the toxicity value hierarchy can be found in section 2 3 of the rsl user s guide below is a brief description of the toxicity hierarchy. Vinyl chloride monomer vcm is a colorless gas with a faint odor.

The toxicity values used in the visl calculator follow the same hierarchy as used in the epa s regional screening levels for chemical contaminants at superfund sites rsl calculator. Shipped as a liquefied gas under own vapor pressure. May asphyxiate by the displacement of air. Vinyl chloride monomer vcm c2h3ci.

Leaks may be liquid or vapor. Vinyl chloride appears as a colorless gas with a sweet odor. Temperature and vapor or saturation pressure for some common fluids. 9 19 reid vapor pressure.

This production method is cheaper than preparing edc from acetylene which is why it has become the major route to vinyl chloride since the late 1950s. When edc in gas phase is heated to 500 c at 15 30 atm 1 5 to 3 mpa pressure it decomposes to produce vinyl chloride and anhydrous hcl. 9 25 saturated vapor pressure temperature degrees f pounds per square inch 50 40 30 20 10 0 10 20 30 40 50 60 70 80 90 100 110 120 3 384 4 501 5 908. Vinyl chloride vapor concentrations between 3 6 and 33 by volume in air are explosive by ignition.

When exposed to open flames. Vcm is used primarily in the production of polyvinyl chloride pvc homopolymer and copolymer resins. Days for evaporation from soil at 1 and 10 cm incorporation respectively based on a high vapor pressure of 2 600 mm hg at 25 degrees c. 78 5 o c 173 o f liquids vapor pressure.

Lower vapor pressure are called heavy components. Vinyl chloride vcm cautionary response information. Degradation product of tce. Aqueous solubility of organic chemicals is generally higher for smaller molecules.

75 psia notes june 1999. Contact with the unconfined liquid may cause frostbite by evaporative cooling. Vinyl chloride vcm 9 20 saturated liquid density temperature degrees f. Vapor pressure for ethanol is for 25 c.

Solubility and vapor pressure for trans 1 2 dichloroethene are for 25 c. Vinyl chloride is an extremely volatile and flammable gas vapor or liquefied gas. Chloroethene chloroethylene ethylene monochloride monochloroethene monochloroethylene vc vcm vinyl chloride monomer vcm colorless gas or liquid below 7 f with a pleasant odor at high concentrations. It should be stored away from direct sunlight in a dry cool and well ventilated area away from incompatible materials.

If vinyl chloride is released to soil it will be subject to rapid volatilization with reported half lives of 0 2 and. 100 o c 212 o f ethyl alcohol.
