Editing Kerosene (section)

=== Chemical processes ===
Aliphatic kerosene is a type of kerosene which has a low aromatic hydrocarbon content. The aromatic content of crude oil varies greatly from oil field to oil field, however by solvent extraction, it is possible to separate aromatic hydrocarbons from aliphatic (alkane) hydrocarbons. A common method is solvent extraction with methanol, DMSO or [[sulfolane]]. Aromatic kerosene is a grade of kerosene with a large concentration of aromatic hydrocarbons, an example of this would be [[Exon]]'s Solvesso 150.

Kerosene is commonly used in metal extraction as the [[diluent]]. For example, in [[copper]] extraction by LIX-84, it can be used in mixer settlers.<ref>{{Cite journal |last1=Ali |first1=Amal I. |last2=Daoud |first2=Jacqueline A. |last3=Aly |first3=Hisham F. |date=October 1996 |title=Recovery of Copper from Sulphate Medium by Lix-84 in Kerosene |url=https://onlinelibrary.wiley.com/doi/10.1002/(SICI)1097-4660(199610)67:23.0.CO;2-S |journal=Journal of Chemical Technology & Biotechnology |language=en |volume=67 |issue=2 |pages=137–142 |doi=10.1002/(SICI)1097-4660(199610)67:2<137::AID-JCTB551>3.0.CO;2-S |bibcode=1996JCTB...67..137A |issn=0268-2575}}</ref>

Kerosene is used as a diluent in the [[PUREX]] extraction process, but it is increasingly being supplanted by [[dodecane]] and other artificial hydrocarbons such as TPH (hydrogenated propylene trimer). Traditionally the UK plants at Sellafield used aromatic kerosene to reduce the radiolysis of TBP while the French nuclear industry tended to use diluents with very little aromatic content. The French nuclear reprocessing plants typically use TPH as their diluent. In recent times, it has been shown by Mark Foreman at Chalmers that aliphatic kerosene can be replaced in solvent extraction with HVO100, which is a second generation biodiesel made by [[Neste]].<ref>{{cite journal | doi=10.1039/D3SU00078H | title=Sustainable solvent extraction of gold and other metals with biomass chemicals | date=2024 | last1=Foreman | first1=Mark R.

In [[X-ray crystallography]], kerosene can be used to store crystals. When a [[Hydrate|hydrated crystal]] is left in air, [[dehydration]] may occur slowly. This makes the color of the crystal become dull. Kerosene can keep air away from the crystal.

It can be also used to prevent air from re-dissolving in a boiled liquid,<ref name="KeroseneMiscellaneous" /> and to store alkali metals such as [[potassium]], [[sodium]], and [[rubidium]] (with the exception of [[lithium]], which is less dense than kerosene, causing it to float).<ref>{{cite web|url=http://www.askiitians.com/iit-jee-s-and-p-block-elements/solved-problems.html|title=S and P Block Elements – Solved Problems for IIT JEE - askIITians|website=www.askiitians.com|access-date=12 December 2017|archive-date=12 December 2017|archive-url=https://web.archive.org/web/20171212193045/http://www.askiitians.com/iit-jee-s-and-p-block-elements/solved-problems.html|url-status=live}}</ref>
