ASTM D1585-15

Standard Test Methods for Fatty Acids Content of Pine Chemicals, Including Rosin, Tall Oil, and Related Products

SIGNIFICANCE AND USE
4.1 These test methods are designed to broaden the scope of the previous edition of these test methods by the inclusion of tall oil as a test material. Test Methods D803 currently includes methods for the determination of the rosin acid and fatty acid content of crude tall oil. Test Methods D803 references Test Method D1585.  
4.2 Rosin and tall oil are composed primarily of rosin acids and fatty acids, and the measurement of these components is important in establishing the composition of these materials.
SCOPE
1.1 These test methods cover the determination of the fatty acids of pine chemicals, including rosin, tall oil, and related products.  
1.2 These test methods may not be applicable to adducts or derivatives of rosin or other pine chemical products.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Summary of Test Method
3.1 The rosin acids content is determined using either the modified potentiometric Wolfe Method or the modified indicator
Wolfe Method described in Test Methods D1240. Rosin acids are calculated as abietic acid.
3.2 The acid number is determined by either the potentiometric or the indicator method in accordance with Test Methods D465.
3.3 The unsaponifiable matter is determined in accordance with the methods described in Test Method D1065.
3.4 The fatty acids are calculated by two methods.
3.4.1 For materials with a fatty acid content less than 5 %, fatty acid content is calculated from the rosin acids content and the
acid number.
3.4.2 For materials with a fatty acid content greater than 5 %, fatty acid content is calculated from the rosin acids and
unsaponifiables content.
3.5 The same method for end point detection, either potentiometric or indicator, should be used for acid number,
unsaponifiables, and rosin acids content determination, in order to avoid slight variables that might occur.
3.6 Since the fatty acids remaining in tall oil rosin, tall oil, and other naval storespine chemical products consist of oleic acid
with varying amounts of other saturated and unsaturated acids, it has become customary to calculate and report the fatty acid
content as oleic acid.
