Summary

A one-pot method is described for the synthesis of naphthalene oligomers polyalkylated with 1-octadecene and 1-hexadecene. The synthesis involves two steps: 1) oligomerization of naphthalene using an AlCl3/CuCl2 catalyst/oxidant system, and 2) polyalkylation with a 1-olefin. Characterization studies include1H- and13C-NMR spectroscopy, GPC and testing methods for lubricants. The degree of alkylation, variations in the alkyl groups, and the position of the substituent on the naphthalene ring were established by13C NMR spectroscopy. The purified products possess excellent properties for being suitable as a lubricant base stock, lubricant additives and functional fluids.
