Preparation of Synthones for Synthetic High Viscosity Oils

Resumo

Cyclopentadiene is alkylated by C₆–C₁₀ monohydric alcohols in the presence of an alkali catalyst. The effects of the cyclopentadiene/alcohol mole ratio, reaction time, and reaction temperature on the yields of normal dialkylpentadienes were elucidated. The hydrogenation of dioctylcyclopentadieneyields the corresponding highly viscous dialkylcyclopentane which can be used as a synthetic oil or additive to mineral oils.
