ABSTRACT:
This application discloses critical parameters, including process conditions and catalysts which effect the alpha:beta ratio of alkylated naphthalene isomers. The use of low alkylation temperatures and of low acidity zeolite catalysts (e.g. steamed USY and zeolite beta) lead to an increase in the alpha:beta ratio. The alkylated naphthalene fluids with higher alpha:beta ratio exhibited significantly enhanced product qualities, including thermal and oxidative stabilities.
