| Abstract: | The determination method for phenol content is described. In the method acetone (or ethanol) is used to dissolve phenolic resin, free phenol is stripped out with water steam and bromometry is used to determine the phenol content. The result shows that the method has high accuracy and its recovery rate ranges from 97% to 102% and it is applicable to the determination of phenol content in phenolic resin. |
