Alcohols, Phenols & Ethers · Nitration of phenol steam distillation

One mole of phenol is treated with dilute HNOX3\ce{HNO3} at 298K to give a mixture of products. The mixture is separated by steam distillation. The steam volatile compound (X) is separated. The increase in percentage of oxygen in (X) with respect to phenol is × 10−1\times\,10^{-1}%

(Given molar mass in g mol−1^{-1} H:1, C:12, N:14, O:16)

We corrected a printing error in the original paper

Source printed “The seam volatile compound”; the source prints no “×\times” between the blank and “10−110^{-1}%”.
