When the pressure on the liquid is suddenly reduced, the liquid becomes superheated; in other words, the liquid is above its normal boiling point at the reduced pressure.
Limonene (shown above), an oil of normal boiling point 178 °C (352 °F), is a major component of orange and lemon oils and is typical of the monocyclic monoterpene hydrocarbons.
For a pure liquid, this pressure depends only on the temperature, the best-known example being the normal boiling point, which is that temperature at which the vapour pressure is equal to the pressure of the atmosphere.
Input parameters for estimation of molecular weight were considered as specific gravity and normal boiling point.
The normal boiling point of twelve dialkylalkyl phosphonates has been determined using gas chromatographic technique.
The correlation model was parameterized using the normal boiling point and specific gravity at 60 °F.
Dibutylhydrogen phosphonate has been used as reference for computing normal boiling point of dialkylalkyl phosphonates.
Molal volume of solute at normal boiling point (cc/g mol).
The group contribution method with help of experimental normal boiling point has good results for predicting the vapor pressures.
Statistical and graphical error analyses normal boiling point revealed that all of the developed models are accurate.
Critical temperature, critical pressure and normal boiling point were selected as inputs for estimation of the acentric factor.
