Phenol, o-cresol, m-cresol, p-cresol, cresylic acid and xylenols for industrial use — Methods of test — Part 2: Determination of water — Dean and Stark method

The principle of the method is based on distillation of a test portion in the presence of an appropriate solvent, in a Dean and Stark apparatus. Determination of the volume of condensate collected in the receiver tube, brought to ambient temperature, assuming this liquid to be water. An appropriate solvent is xylene, solvent naphtha or alternatively, toluene. ISO 1897-2 replaces ISO/R 1898-1971.
