General description

Pentane, a linear aliphatic hydrocarbon, is one of the main constituents of light straight-run (LSR) gasoline fraction in crude oils. Its isomerization can improve the octane number of gasoline. This has led to the development of a number of metal catalysts, which can effectively isomerize n-pentane to iso-pentane.

Application

Pentane may be used as a solvent in the preparation of tetraethynyl silane from tetrakis((trimethylsilyl)ethynyl)silane.

Qualitative and semi-quantitative analysis of organosulfides extracted from oil obtained by steam distillation of yellow onions was performed by gas chromatography-mass spectrometry (GC-MS). The extraction efficiency of organosulfides from onion oil was evaluated across four solvents: dichloromethane; diethyl ether; n-pentane;
