Measurement of vapor pressure of palm oil constituents under vacuum
Vapor pressure is one of the most important properties in chemical process design for unit operations like distillation, extraction an absorption processes. Even though, vapor pressure data for most of the commonly used chemical compounds are available in the literature and the data bank is continuo...

Vapor pressure is one of the most important properties in chemical process design for unit operations like distillation, extraction an absorption processes.

Vapor pressure of vegetable oils are not easily determined due to its complex nature (chemical composition) and temperature sensitivity. The vapor pressure measurements of all phlegmatic liquids including oils and its main constituent triglycerides, require a method which impose a minimum of thermal hazard to the substance under examination.
