The measurements were made with a Brookhaven Instruments BI-DCP disc centrifuge photosedimentometer using the following procedures: About 0.2 mL of 100% ethanol, 14 mL of a 0.1 vol.% Triton X-100 aqueous solution and 0.1 ml dodecane
was injected into the non-spinning disc to prevent evaporative cooling.
An example of the solubility potential results obtained for three hypothetical polymers and a fuel candidate blended with dodecane
is shown in Figure 3.
Yields are determined by GC using dodecane
as an internal standard.
Pectin Furfural Alginate Undecane, dodecane
, styrene, benzene.
Of the 3 non-irritating chemicals only dodecane
was predicted correctly in all laboratories.
In another study against Phytoplasma pathogenicity indicated metabolite changes caused in leaves and phloem sap leading to change in quantity of various compounds along with the following mentioned eicosane, tetradecane, 5-methyltetradecane, heneicosane, heptadecane, dodecane
, hexatriacontane, pentatriacontane, tetrapentacontane, Tetratetracontane and 3,7-dimethyldecane (Gai et.
No correlation was found to exist between the contact angle of water or dodecane
and stain repellency to nine different household chemicals.
Aliphatic unbranched and branched long chain hydrocarbons from dodecane
to tetracosane form the last important compound group.
Heavier unsaturated hydrocarbons in paraffin series, nonane, decane, undecane, and dodecane
, may occur in gasoline and in the exhausts--most often the nonane--but they have dominant sources in releases from consumer products (mainly from industrial synthetic building materials and housing equipment ), from the industrial waste streams and the contaminated urban soil [36-40], though environmental behavior of the vapors from the subsurface gasoline contamination of soil and groundwater is not a well understood phenomenon.
2), including 11 different hydrocarbons (no-nane 3.23%, decane 1.61%, limonene 9.08%, dodecane
5.44%, tetradecane 7.83%, dotriacontane 9.25%, ethylbenzene 2.70%, 1,3-dimethyl benzene 5.70%, biphenyl 7.97%, octane 1.58%, and hexadecane 11.39%), 2 alcohols (dimethyl hexadecanol 2.18% and borneol 16.02%), and 1 aldehyde (nonaldehyde 16.05%).
Among them the liquid alkanes (undecane dodecane
tridecane tetradecane pentadecane hexadecane heptadecane etc.) are widely used in fuel oils and as anti-corrosive agents in lubricating oils and solid alkanes (octadecane nonadecane eicosane heneicosane tricosane tetracosane heptacosane octacosane etc.) find their use in paraffin waxes of different kinds.
Generally, paraffin, decalin, dodecane
, p-xylene, 1, 2, 4-trichlorobenzene, and kerosene are used to dissolve UHMWPE [12-17].
