• Mark:

  Scheme 2

• Associated context:

  Notably, a high yield (97%) of hexadecanol was obtained, and this compound is used widely in surfactants, lubricants, plasticizers, emulsifiers, cosmetics, and biofuels. As the temperature increased to 2208C, the palmitic decanol first accumulated to 63.2% at 3 h and then diminished gradually as the reaction processed; this indicates that the palmitic acid was initially hydrogenated rapidly to hexadecanol. For prolonged reaction times, the yield of n-C₁₆ alkane increased gradually as the hexadecanol decreased gradually. The proposed pathways are shown in Scheme 2.
