The determination consists in neutralizing the free acids using a standard volumetric alkali solution. It is not applicable to essentail oils containing lactones. The determination is carried out in a saponification flask, round-bottomed, of alkali-resistant glass, capacity 100 to 200 ml, and to which can be fitted a glass tube, at least 1 m in length and at least 1 cm internal diameter. The tube acts as a reflux cooler.
