ABSTRACT:
Alkylaromatic lubricant products are produced by the reaction of a long chain alkyne such as octyne, decyne or dodecyne over a reduced Group VIB metal oxide catalyst, preferably reduced chromium on silica. The products, which are predominantly n-alkyl substituted, possess excellent thermal and oxidative stability and may be used as lubricant base stocks and viscosity improvers.
