ABSTRACT:
Decene oligomers useful with or without hydrogenation as basis for synthetic lubricating oils are prepared by oligomerizing decene-1 in the presence of an alkylaluminum chloride catalyst and an alkyl halide cocatalyst, in a first reaction stage the decene-1 being mixed with the catalyst at from 0 to +25.degree. C. and being kept in contact therewith within the same temperature range for not less than 15 minutes and in a second reaction stage the cocatalyst being added at from 0 to +35.degree. C. in the course of a period of from 15 to 180 minutes.
