Paraffin oil is commonly used to fill Galileo thermometers: Due to paraffin oil's freezing temperature being lower than that of water (approx. −4 °C (24 °F)), this makes them less susceptible to freezing during shipment, or when stored in a cold environment. [37]
The gel point of petroleum products is the temperature at which the liquids gel so they no longer flow by gravity or can be pumped through fuel lines. This phenomenon happens when the petroleum product reaches a low enough temperature to precipitate interlinked paraffin wax crystals throughout the fluid .
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Palmitic acid was discovered by Edmond Frémy (in 1840) in the saponification of palm oil, which process remains today the primary industrial route for producing the acid. [13] Triglycerides (fats) in palm oil are hydrolysed by high-temperature water and the resulting mixture is fractionally distilled .
The melting point of hydrogenated coconut oil is 36–40 °C (97–104 °F). In the process of hydrogenation, unsaturated fats (monounsaturated and polyunsaturated fatty acids) are combined with hydrogen in a catalytic process to make them more saturated. Coconut oil contains only 6% monounsaturated and 2% polyunsaturated fatty acids.
It is a high-volume profitable product produced in crude oil refineries. [1] ... With a boiling point near 85 °C (185 °F) (n-octane boils at 125.62 °C ...
The sample is then cooled and inspected for pour point as per the usual pour point method. The method usually gives higher pour point because the thermal history has not been cancelled by a prolonged thermal treatment. The lower pour point is measured by first pouring the sample into a stainless steel pressure vessel. The vessel is then screwed ...
