Idrialin is a mineral wax which can be distilled from the mineral idrialite.
[1] According to G. Goldschmidt of the Chemical Society of London, it can be extracted by means of xylene, amyl alcohol or turpentine; also without decomposition, by distillation in a current of hydrogen, or carbon dioxide.
It is a white crystalline body, very difficultly fusible, boiling above 440 °C (824 °F).
Its solution in glacial acetic acid, by oxidation with chromic acid, yielded a red powdery solid and a fatty acid fusing at 62 °C, and exhibiting all the characters of a mixture of palmitic acid and stearic acid.
