Phenanthrene (98%) and n-tetradecane (olefin free, [greater than or equal to] 99.
Membrane swelling in feed mixtures of phenanthrene (solute) in n-tetradecane was determined by gravimetric sorption experiments.
20 h in pure n-tetradecane and in feed mixture containing phenanthrene (150 ppm) in n-tetradecane at different temperatures is represented in the Fig.
n-tetradecane (chromatographic pure, from Acros Organics.
24) The residual monomer content can be detected by GC analysis with n-tetradecane as the internal standard.
The PCM material utilized for the experimental model is a technical grade of n-tetradecane.
For PCM materials testing, a sample of technical grade n-tetradecane is encapsulated in clear, 1/2 inch (12.
The simultaneous distillation and extraction (SDE) method was chosen for essential oil isolation using Marcusson's type micro-apparatus with n-hexane (500 [micro]L) as solvent and n-tetradecane (2 [micro]L) as internal standard.
The yields of the oil isolated by the SDE method from aromatic plants were calculated by the internal standard method using pure n-tetradecane (> 99.
That's about 50 [degrees] C higher than the temperature that reduced the petroleum fuel, n-tetradecane
, to coke, says Andresen.
For the isolation of aroma compounds from peppermint and orange samples SDE Marcusson's micro-apparatus with n-hexane (500 [micro]L) as solvent and n-tetradecane (1 [micro]L) as internal standard was used.
st] is the content of n-tetradecane in the sample, mg/g.
