| Common Name | 1-Pentanol |
|---|
| Description | 1-Pentanol, also known as butylcarbinol or 1-pentyl alcohol, belongs to the class of organic compounds known as primary alcohols. Primary alcohols are compounds comprising the primary alcohol functional group, with the general structure RCOH (R=alkyl, aryl). Thus, 1-pentanol is considered to be a fatty alcohol lipid molecule. 1-Pentanol is an organic compound with the formula C5H12O. 1-Pentanol is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. All eight isomers of 1-Pentanol are known:; It is a colourless liquid of density 0.8247 g/cm3 (0 oC), boiling at 131.6 oC, slightly soluble in water, easily soluble in organic solvents. 1-Pentanol exists in all eukaryotes, ranging from yeast to humans. 1-Pentanol is a sweet, balsamic, and fusel tasting compound. 1-Pentanol can be found in a few different foods, such as black walnuts, common thymes, and tea and in a lower concentration in safflowers, highbush blueberries, and kohlrabis. 1-Pentanol has also been detected, but not quantified, in several different foods, such as corns, garden tomato (var.), allspices, cherry tomato, and evergreen blackberries. It possesses a characteristic strong smell and a sharp burning taste. The other amyl alcohols may be obtained synthetically. It is a solid that melts at 48 to 50 °C and boils at 112.3 °C. On passing its vapour through a red-hot tube, it decomposes with production of acetylene, ethylene, propylene, and other compounds. Of these, tertiary 1-Pentanol has been the most difficult to obtain, its synthesis having first been reported in 1891, by L. Tissier (Comptes Rendus, 1891, 112, p. 1065) by the reduction of a mixture of trimethyl acetic acid and trimethylacetyl chloride with sodium amalgam. It is oxidized by chromic acid to isovaleraldehyde, and it forms crystalline addition compounds with calcium chloride and tin(IV) chloride. When pure, it is nontoxic, while the impure product is toxic. |
