N-Octane
99%
It is mainly used in organic synthesis, edible oil extraction solvents and extractants, such as cleaning in the electronics industry, as an extractant in the pharmaceutical industry, and can also be used as a solvent for rubber and coatings.
1. Product Introduction
The chemical formula of octane is C8H18, the eighth member of alkanes. There are 18 isomers (22 if stereoisomers are included). Among them, the isomer 2,2,4-trimethylpentane has very low detonation phenomenon when used as gasoline engine fuel, so it is set as the standard of octane number 100. The 18 isomers are: n-octane; 2-methylheptane; 3-methylheptane; 4-methylheptane; 2,2-dimethylhexane; 3,3-dimethylhexane; 3-ethylhexane; 2,3-dimethylhexane; 2,4-dimethylhexane; 2,5-dimethylhexane; 3,4-dimethylhexane; 2,3,4-trimethylpentane; 2,2,3-trimethylpentane; 2,2,4-trimethylpentane; 2,3,3-trimethylpentane; 2-methyl-3-ethylpentane; 3-methyl-3-ethylpentane; 2,2,3,3-tetramethylbutane.
