Title:
PRODUCTION OF SYNTHETIC LUBRICANT
Document Type and Number:
Japanese Patent JPS62106994
Kind Code:
A
Abstract:
A process for preparing synthetic lubricating materials which process comprises:
a) reacting a C6- and/or C8- olefin component containing fraction with a linear olefin reactant having an average carbon number ranging from 10 to 18 in the presence of a catalyst comprising pentavalent tantalum, halogen, oxygen and an inorganic oxide substrate wherein at least one valence of tantalum is bound to oxygen which is bound to the substrate, at least one valence at the tantalum is bound to halogen and the remaining tantalum valences are bound to halogen and/or oxygen;
b) separating from the reaction mixture of a) hydrocarbons which distil at a temperature above 316 DEG C; and
c) hydrogenating the reaction product of b) by contact with hydrogen at a temperature ranging from 25 to 300 DEG C.
