Scope
This standard specifies the principles, reagents, and instruments for determining the content of phenols and their homologues in crude phenols, as well as the experimental steps, result calculation, and precision. This standard is applicable to the determination of the content of phenols and their homologues in crude phenols obtained from the fractional distillation of high-temperature coal tar.
