What is BS EN 15168- Determine the hydroxyl value of aliphatic and cyclic hydroxyl compounds about?
BS EN 15168 discusses surface-active agents. BS EN 15168 specifies a method for the determination of hydroxyl value of aliphatic and cyclic hydroxyl compounds with hydroxyl groups attached to primary and secondary carbon atoms.
BS EN 15168 is applicable to polyacetals, temperature-sensitive materials, high solids polymer polyols and rigid polyols and phenols.
Note: BS EN 15168 is not suitable for the determination of hydroxyl groups attached to tertiary carbon atoms
Who is BS EN 15168- Determine the hydroxyl value of aliphatic and cyclic hydroxyl compounds for?
BS EN 15168 on determining the hydroxyl value of aliphatic and cyclic hydroxyl compounds is useful for:
- Detergent manufacturers
- Quality control personnel
- Testing laboratories
Why should you use BS EN 15168- Determine the hydroxyl value of aliphatic and cyclic hydroxyl compounds?
A known mass of test sample is reacted with an excess of p-toluenesulfonyl isocyanate to form an acidic carbamate. Water is added to convert un-reacted isocyanate to sulfonamide followed by direct potentiometric titration of the acidic carbamate with tetra-n-butyl ammonium hydroxide in a non-aqueous medium.
