1-Hexanol is an aliphatic , primary alcohol from the homologous series of alkanols . It has the empirical formula C 6 H 14 O. On the basis of this empirical formula, sixteen other constitutionally isomeric alcohols can be formulated, the hexanols .

Extraction and presentation

1-Hexanol can be produced isomer-free with the help of the so-called Alfol process : The process developed by the German chemist Karl Ziegler provides for an organic aluminum synthesis based on ethene .

properties

1-Hexanol is a clear, colorless liquid with a pleasantly sweet odor that is easily flammable. The flash point is 60  ° C . At a temperature of 280 ° C, the compound ignites itself. In water it dissolves hardly in 175 ml of water is only 1 ml hexanol solve. An azeotrope boiling at 97.8 ° C. is formed with water . The azeotrope composition is 67.2% by mass of water and 32.8% by mass of 1-hexanol.

use

1-Hexanol is sometimes used in organic chemistry as a solvent for hydrocarbons, shellac, linseed oil, hormones and many resins. It is also used as an intermediate in the manufacture of surfactants, plasticizers and insect repellants. It is also used in heat cost allocators based on the evaporation principle .
