Abstract
Some evidence is given for the presence of a solid phase just below the melting point of stearic acid. It is not certain whether the existence of this new phase is due to impurities or not.
Résumé
On donne plusieurs preuves de la présence d'une phase solide juste au-dessous du point de fusion de l'acide stéarique. Il n'est pas certain que l'existence de cette phase nouvelle soit due à des impuretés ou non.
Zusammenfassung
Einige Beweise zur Gegenwart einer Festphase knapp unterhalb des Schmelzpunktes der StearinsÄure werden gegeben. Es ist nicht geklÄrt ob das Vorhandensein dieser neuen Phase auf Verunreinigungen zurückzuführen ist oder nicht.
