2,4,4-Trimethyl-2-pentene Usage And Synthesis
Chemical PropertiesCLEAR COLOURLESS TO VERY SLIGHTLY YELLOW LIQUID
UsesOrganic synthesis.
Uses2,4,4-Trimethyl-2-pentene was used to study the kinetics of liquid-phase hydrogenation of isooctenes on Pd/γ-Al2O3 catalyst in semibatch reactor. It was used in the analysis of butene oligomerate produced over solid and liquid phosphoric acid by GC-MS techniques.
Purification MethodsFractionate it under N2 as it is highly flammable. [Beilstein 1 III 848, 1 IV 891.]
