The present invention provides a method for purifying an organic compound, by which an organic compound having a reduced lead content is obtained from an organic compound that contains a lead component as an impurity. In this method for purifying an organic compound, the organic compound that contains a lead component is irradiated with ultraviolet light, and the lead component is subsequently removed from the organic compound. The present invention also provides a method for producing an organic compound, said method comprising purification of the organic compound by means of the above-described method for purifying an organic compound.

The present invention relates to a method for the production of molecules with seven carbons constituted by a chain of four carbons with three methyl branches, primarily triptane (2,2,3-trimethylbutane), by alcohol coupling reaction (Guerbet reaction), resulting in an alcohol with a four-carbon chain with three methyl branches, which is transformed into triptane. The importance of this method stems from the fact that triptane is the hydrocarbon with the greatest capacity to resist compression without ignition and can be used in unleaded aviation gasolines and in the formulation of high-octane automotive gasolines.
