PREPARATION OF SYNTHETIC LUBRICANT BASE STOCKS FROM POLY(ISOBUTYLENE) AND LINEAR OLEFINS

PREPARATION OF SYNTHETIC LUBRICANT BASE STOCKS FROM POLY(ISOBUTYLENE) AND LINEAR OLEFINS

High yields of synthetic lubricant base stocks with high viscosities and high viscosity indices can be obtained by oligomerizing linear olefins having 10 to 24 carbon atoms in the presence of up to 10 weight % of poly(isobutylene). The oligomerization catalysts are acidic calcium montmorillonite cla...

Zusammenfassung:High yields of synthetic lubricant base stocks with high viscosities and high viscosity indices can be obtained by oligomerizing linear olefins having 10 to 24 carbon atoms in the presence of up to 10 weight % of poly(isobutylene). The oligomerization catalysts are acidic calcium montmorillonite clays having a moisture content of up to 20 weight %, a residual acidity of 3 to 30 mg KOH/g, and a surface area of 300 m /g or greater.
