PALMITIC ACID, n-Hexadecylic Acid, Ch3(Ch2)14c02h, an organic acid found as a glyceride, palmitin, in all animal fats, and partly as glyceride and partly uncombined in palm oil.
By saponification it yields a number of fatty acids - palmitic, myristic, oleic, linolic, linolenic and isolinolenic. Exposed to the air in thin films, linseed oil absorbs oxygen and forms " linoxyn," a resinous semi-elastic, caoutchouclike mass, of uncertain composition.
It contains palmitic and several other fatty acids, among which there is one - ricinoleic acid - peculiar to itself.
In this field he contributed to our knowledge of the manufacture of iron and steel, sulphuric acid, glass and paper, and in particular worked at the saponification of fats with sulphuric acid and the utilization of palmitic acid for candle-making.
Meyerdahl obtained 4% of palmitic acid, 20% of jecoleic acid, C19H3602, and 20% of therapic acid, C 17 H 28 O 2; other investigators have recognized jecoric acid, C 18 H 30 O 2, asellic acid, C17H3202, and physetoleic acid, C16Hn02, but some uncertainty attends these last three acids.
