Abstract: Alkylated naphthalene blendstock and processes for making the alkylated naphthalene blendstock are provided. The present processes comprise mixing an acid-form MWW-type catalyst, naphthalene, and a solvent to provide a reaction mixture and adding linear alpha olefins to the reaction mixture after heating. The resulting AN blendstock has an isomer ratio of less than 45 wt % mono alkylated naphthalene and greater than 55 wt % multi-alkylated naphthalene and can be combined with polyalphaolefin base stock to provide a synthetic lubricant formulation produced without triflic catalyst and with less process steps.
