Higher alcohols for industrial use — Methods of test — Part 6: Determination of ash
Relates to C6 to C13 alcohols. The principle of the method is based on burning of a test portion and heating in a platinum or silica dish at (600 +- 30) °C to constant mass. ISO 1843/6 replaces ISO Recommendation R 1851-1970.
Higher alcohols for industrial use — Methods of test — Part 1: General
Gives general instructions for C6 to C13 alcohols and also specifies the methods to be used for the measurement of the colour, the determination of the density at 20 °C and the determination of the water content.
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.
Higher alcohols for industrial use — Methods of test — Part 4: Determination of bromine number — Tit...
Relates to C6 to C13 alcohols. The principle of the method consists in titration of test portion with standard volumetric potassium bromide/bromate solution in the presence of methyl orange as indicator.
