Summary The effect on the determination of the acetone numbers of thermally polymerized drying oils of temperature, water, color, and method of determining the end point has been reported. A simple standardization has been developed. With proper precautions a reproducibility of ± 0.16 at an acetone number of 94 can be obtained. From a study of various bodied oils it is concluded that the acetone number is a function of the kind of oil, its viscosity, amount of acids present, processing conditions such as temperature and oxidation by air, and the addition of polar modifying agents such as maleic anhydride. The acetone number promises to be a useful constant of bodied oils.
