The saturation vapor curve is the curve separating the two-phase state and the superheated vapor state in the T-s diagram. Typical techniques for such measurements include the use of thermogravimetry and gas transpiration.

Xylene vapor pressure curve. Equations of state for the xylene isomers o-xylene m-xylene and p-xylene and ethyl-benzene have been developed with the use of the Helmholtz energy as the fundamental property with independent variables of density and temperature. The general uncertainties of the equations of state are 05 in vapor pressure above the normal boiling point and. Thermodynamic Equilibria in Xylene Isomerization.

Xylene from Greek ξύλο xylo wood xylol or dimethylbenzene is any one of three isomers of dimethylbenzene or a combination thereof. With the formula CH 3 2 C 6 H 4 each of the three compounds has a central benzene ring with two methyl groups attached at substituentsThey are all colorless flammable liquids some of which are of great industrial value. Lower vapor pressure are called heavy components.

Xylene is a colourless sweet-smelling liquid. Xylene occurs naturally in petroleum and coal tar. Chemical industries produce xylene from petroleum.
It is also used as a cleaning agent and a thinner for paint and in paints in glues in printing inks and in varnishes. Xylene evaporates quickly from the soil and surface water into the air. The experimental data shown in these pages are freely available and have been published already in the DDB Explorer Edition.
The data represent a small sub list of all available data in the Dortmund Data Bank. For more data or any further information please search the DDB or contact DDBST. The general uncertainties of the equations of state are 05 in vapor pressure above the normal boiling point and increase as the temperature decreases due to.
2-Xylene is a clear flammable liquid. It has a sweet aromatic odor. 2-Xylene is moderately soluble in water.
2-Xylene occurs naturally in coal tar various plants and is released during forest fires. It is a component of cigarette smoke. 2-Xylene is an important commercial chemical used to make other chemicals pharmaceuticals dyes insecticides and in gasoline blending.

Above 32C use a closed system ventilation and explosion-proof electrical equipment. Prevent build-up of electrostatic charges eg by grounding. Use water spray powder foam carbon dioxide.
In case of fire. Keep drums etc cool by spraying with water. AVOID EXPOSURE OF PREGNANT WOMEN.
Rescuer Protection Xylene vapor is a mild respiratory-tract irritant. The liquid is a mild skin irritant with slow skin absorption. Positive-pressure self-contained breathing apparatus SCBA is recommended in response situations that involve exposure to potentially unsafe levels of xylene vapor.
The saturation vapor curve is the curve separating the two-phase state and the superheated vapor state in the T-s diagram. The saturated liquid curve is the curve separating the subcooled liquid state and the two-phase state in the T-s diagram. Typically most of nuclear power plants operates multi-stage condensing steam turbines.
In these turbines the high-pressure stage receives. The vapor pressure of dry ice is 573 MPa 565 atm at 20 C which would cause most sealed containers to rupture. Due to their often extremely low values measurement of the vapor pressure of solids can be rather difficult.
Typical techniques for such measurements include the use of thermogravimetry and gas transpiration.
