What is 2,2-DIMETHYLHEXANE?
General Description
2,2-Dimethylhexane is one of the products of the corona discharge of a simulated Titan′s atmosphere (2% argon in nitrogen and 10% methane) at 500 Torr and 298 K (using GC-FTIR-MS techniques). It was used to study the adsorption of linear and branched alkanes on a microporous silicoaluminophosphate material (SAPO-5) using chromatographic techniques.
Purification Methods
Dry the hexane over type 4A molecular sieves and distil it. [Beilstein 1 IV 432.]
