Esters of pentaerythritolVapor pressureEnthalpy of vaporizationPentaerythritol esters (2,2- bis (hydroxymethyl)propane-1,3-diol) esters and other esters are widely used as components of machine oils, motor oils,
The vapor pressure of a chemical compound is a measure of its volatility: the higher the vapor pressure at a given temperature, the greater the probability that the substance is in the gaseous state rather than the condensed phase (liquid or solid). The vapor pressure of a substance increases...
An average of 1.48 mg/kg body weight has been found in eels [6]. It is not currently regulated in either the US or the European Union. This work reports the vaporization enthalpy and vapor pressure of both (−) Ambroxide and commercial Galaxolide using both n-alkanes and a mixture...

Before the introduction of chlorofluorocarbons, sulfur dioxide (enthalpy of vaporization, 6.00 kcal/mol) was used in household refrigerators. What mass of SO2 must be evaporated to remove as much heat as evaporation of 1.00 kg of CCl2F2 (enthalpy of vaporization is 17.4 kJ/mol)? The vaporizatio...
Heat of Vaporization:The heat of vaporization is the amount of energy associated with the phase change of 1 mol substance from liquid to gas at its boiling point. The unit of heat vaporization is kJmol.Answer and Explanation: The vapor pressure of a substance (p), the temperature (T), ...
Development of a device to valuate the effect of ethanol on the vapor pressure and vaporization enthalpy of fuel gasolines The quality of the gasoline utilized for fueling internal combustion engines with spark ignition is directly affected by the gasolines properties. Thus, th... R Cataluña,R...
