Ethylbenzene is an organic compound with the formula C 6 H 5 CH 2 CH 3. It is a highly flammable, colorless liquid with an odor similar to that of gasoline . This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene , the precursor to polystyrene , a common plastic ...
The following list has substances known to be gases, but with an unknown boiling point. Fluoroamine; Trifluoromethyl trifluoroethyl trioxide CF 3 OOOCF 2 CF 3 boils between 10 and 20° [142] Bis-trifluoromethyl carbonate boils between −10 and +10° [37] possibly +12, freezing −60° [143]
If ethylbenzene is included, the mixture is sometimes referred to as BTEX. The BTX aromatics are very important petrochemical materials. Global consumption of benzene, estimated at more than 40,000,000 tons in 2010, showed an unprecedented growth of more than 3,000,000 tons from the level seen in 2009.

There are two conventions regarding the standard boiling point of water: The normal boiling point is commonly given as 100 °C (212 °F) (actually 99.97 °C (211.9 °F) following the thermodynamic definition of the Celsius scale based on the kelvin) at a pressure of 1 atm (101.325 kPa).
boiling point. Also vaporization point. The temperature at which a substance changes state from a liquid to a gas (or vapor). It depends on pressure and is usually specified for a given substance under standard conditions. boiling-point elevation The process by which a substance's boiling point is elevated by adding another substance. bond
In thermodynamics, Trouton's rule states that the (molar) entropy of vaporization is almost the same value, about 85–88 J/(K·mol), for various kinds of liquids at their boiling points. [1] The entropy of vaporization is defined as the ratio between the enthalpy of vaporization and the boiling temperature.
