Basic Info

What is Undecane?

Undecane (also known as n-Hendecane) is a liquid alkane with the chemical formula of CH 3 (CH 2) 9 CH 3. It is used as a mild attractant for various types of moths and cockroaches, and as an alarm signal for various ants. There are 159 isomers.

When working with other hydrocarbons, undecanone can also be used as the internal standard in gas chromatography. Since the boiling point of undecane (196 ° C) is well known, it can be used as a comparison of the retention time of molecules whose structure has just been clarified in the gas chromatograph. For example, if a 50 m cross-linked methyl silicone capillary column is used, the temperature of the column box will rise slowly, starting from about 60 ° C, then the undecanon molecule (such as undecanone) can be used as the internal standard, and the retention time can be compared with other 10, 11 or 12 carbon molecules, depending on their structure.

Octane is obtained from petroleum refining. The alkanes are separated by selective adsorption and then fractionated to produce the desired n-alkane mixture (63)

Undecane Uses

  1. Chromatographic analysis standard. Petroleum research. Organic synthesis.
  2. The preparation method of undecanone used for small size hollow silica.
  3. It is used to produce 11-carbon dicarboxylic acid, high-grade electronic cleaning fluid, chlorinated paraffin, environment-friendly dry cleaning agent, etc.
  4. Undecane is primarily made use of as a model n-alkane in the study pertaining to the viscosity, excess molar enthalpy as well as gas-liquid balance of binary alkane mixes.
