General Description

2,3-DIMETHYLHEPTANE is a chemical compound with the molecular formula C9H20. It is a branched alkane featuring a seven-carbon chain with two methyl groups attached to the second and third carbon atoms. 2,3-DIMETHYLHEPTANE is a colorless liquid with a high boiling point and is insoluble in water. It is commonly used as a solvent in industrial applications and as a fuel additive to improve the octane rating of gasoline. Due to its branched structure, 2,3-DIMETHYLHEPTANE exhibits reduced reactivity compared to straight-chain alkanes, making it a relatively stable compound. Its main use is as a high-octane component in gasoline blends to enhance engine performance.

GAS-TO-LIQUID REACTOR AND METHOD OF USING

A device and a process to propagate molecular growth of hydrocarbons, either straight or branched chain structures, that naturally occur in the gas phase to a molecular size sufficient to shift the natural occurring phase to a liquid or solid state is provided. According to one embodiment, the device includes a grounded reactor vessel having a gas inlet, a liquid outlet, and an electrode within the vessel; a power supply coupled to the electrode for creating an elecirostatic field within the vessel for converting the gas to a liquid and or solid state.

IONIC ALKYLATION OF TERTIARY ALKYL HALIDES WITH TETRAALKYLSILANES

In the reaction of tertiary alkyl halides with tetraethyl-, tetrapropyl-, tetrabutyl-, and tetraamylsilane in the presence of AlX3 the halogen atom is substituted by the alkyl group with the formation of the corresponding saturated hydrocarbons containing a quaternary carbon atom.As a result of the hydride mobility of the β-hydrogen atom in the tetraalkylsilane ionic hydrogenolysis of the substrate occurs in addition to alkylation, and the degree of hydrogenolysis depends on the alkyl substituent in the silane.
