Abstract
Abstract A process is provided for dimerizing 1-olefins which comprises contacting such olefins in a reaction zone with a minor proportion of at least one catalyst selected from the group consisting of phosphoric acid-promoted and water-promoted boron trifluoride catalyst in a mole ratio of catalyst to olefins of from about 0.005:1 to about 0.1:1 and at a temperature from about 100*C. to about 150*C.
