Название (англ.):
Phenol, o-cresol, m-cresol, p-cresol, cresylic acid and xylenols for industrial use; Methods of test; Part 13 : Determination of residue on distillation (Cresylic acid and xylenols only)
Описание (англ.):
Applicable to products having a high o-cresol content and a high m-cresol content. The principle consists in distillation of a tast portion under carefully defined conditions and determination of the mass of residue obtained. The distillation is carried out according to ISO 918. When all the water has distilled over, continue the distillation without intermediate measurements, until either the dry point or the final boiling point is reached.
