Abstract: 1-decene oligomerization was studied using pentaerythrotol as initiator and BF3 as catalyst. The effect of mass ratio of pentaerythrotol/1-decene, reaction time and temperature on the reaction as well as the best conditions for 1-decene oligomerization and the recyclability of pentaerythrotol were investigated. The oligomerization products were analyzed by gas chromatography. The results indicate that at the conditions of mass ratio of 1-decene/pentaerythrotol of 10, 20 ℃ and 2.5 h, the conversion of 1-decene oligomerization is up to 97.90%. The yield of trimer and tetramer together is 84.17%. The recycling effect of pentaerythritol is good. The product can be used to prepare high performance synthetic lubricant base oil.
