Process for treating a composition containing renewable isododecane

A process for treating a composition containing renewable isododecane, the process comprising:

• a) selecting a first composition containing at least 20% renewable isododecane;
• b) treating the first composition with Oleum to provide an Oleum treated first composition;
• c) adding water to the Oleum treated first composition to provide an aqueous mixture of the Oleum treated first composition and agitating the aqueous mixture;
• d) allowing an aqueous phase and a non-aqueous phase of the aqueous mixture to separate, wherein the aqueous phase comprises oxidized compounds, sulfonized compounds, or a combination of oxidized compounds and sulfonized compounds, and the non-aqueous phase comprising the renewable isododecane;
• e) removing the aqueous phase from the aqueous mixture in order to isolate the non-aqueous phase comprising the renewable isododecane;
• f) adding an alkaline aqueous washing solution to the non-aqueous phase comprising the renewable isododecane;
• and
• g) removing the aqueous washing solution of step f), to obtain a second composition containing renewable isododecane.
