Higher alcohols for industrial use — Methods of test — Part 2: Determination of acidity to phenolpht...
Relates to C6 to C13 alcohols. The principle consists in titration of a test portion with standard volumetric sodium hydroxide solution, in ethanolic, using phenolphthalein as indicator. The result is expressed in milliequivalents per kilogram. Alternatively, the acidity may also be expressed in terms of the acid value.
Higher alcohols for industrial use — Methods of test — Part 3: Determination of carbonyl compounds c...
Relates to C6 to C13 alcohols. The principle bases on reaction of carbonyl compounds present in a test portion with hydroxylammonium chloride to from an oxime, and potentiometric titration of the hydrochloric acid liberated with standard volumetric ethanolic potassium hydroxide solution.
