    ECHINOPS OIL—SOYA BEAN OIL The characteristics found by Wijs ^ in specimens of the oil, containing 44 per cent and 7-3 per cent of free fatty acids respectively, are given in the following tables. The oil absorbs 9 per cent of oxygen {Weger's method). 1000 c.c. of absolute alcohol at 15° C. dissolve 51 gi-ms. of the neutral oil (freed from fatty acids). The acetyl value of one specimen was 26-5. The oil gives neither the Halphen nor the Baudouin reaction. Physical and Chemical Characteristics of Echinops Oil Speciflo Gravity. Saponification Value.
