2,4,4-TRIMETHYL-2-PENTENE Chemical Properties,Usage,Production

Chemical Properties

CLEAR COLOURLESS TO VERY SLIGHTLY YELLOW LIQUID

Uses

Organic synthesis.

Uses

2,4,4-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.
