Synthesis and Optimization of Ethylene Trimerization Using [Bis-(2-dodecylsulfanyl-ethyl)-amine]CrCl3 Catalyst |
The bis-(2-dodecylsulfanyl-ethyl)-amine (SNS) ligand was prepared in good yield and high purity using inexpensive reagents and reacted with CrCl3(THF)3 at room temperature to give the corresponding SNS/CrCl3 catalyst in high yield. An ethylene trimerization reaction at 90 C and 23 bar ethylene, using the SNS/CrCl3 complex activated by 700 equivalents of MAO, afforded 99.97% 1-C6. Only 0.10% PE was produced and the catalyst activity was 159283 g/g Cr/h. |
