Abstract

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.
