Beschreibung

Allgemeine Beschreibung

1-Dodecanol, a fatty alcohol, is a long chain aliphatic alcohol. Solid-liquid phase diagrams of its binary mixtures with various other fatty alcohols (1-tetradecanol, 1-hexadecanol and 1-octadecanol) have been evaluated by employing high pressure microscopy and DSC (Differential scanning calorimetry). It undergoes oxidation in the presence of multiwall carbon nanotubes (MWCNTs) supported MoO₃ (Mo/MWCNTs) and potassium containing Mo/MWCNTs (K/Mo/MWCNTs) catalysts to afford 1-dodecanal. Its oxidation in the presence of Ru and Pt based carbon catalysts has been reported.

Anwendung

1-Dodecanol may be employed as an extraction reagent in the pipette vial dispersive liquid-liquid microextraction method coupled with HPCL studies.
