To quickly assess the difficulty of the text, read a short excerpt:
The solution was then filtered, the filtrate acidified, the phenol ethyl ester extracted with carbon tetrachloride, and identified by its melting point, 247. The unsaponified colorless phenol diethyl ester was col- lected from the filter and identified by the melting point, 251. In order to determine whether any rearrangement of the esters took place under the conditions of the experiment, I dissolved 0. 0524 gram of the colorless phenol ester and 0. 5500 gram of the colored quinone ethyl ester... in 5 cc. Of 40 per cent alcohol with ethyl iodide in o . 3 N solution of 40 per cent alcohol and heated the mixture a number of hours in a sealed tube in the bath at 60. The tube was then opened and after separation 0. 0516 gram of the colorless phenol ethyl ester and 0. 5494 gram of the colored quinone ethyl ester were recovered. I then dissolved 0. 6024 gram of the sodium salt of the phenol ethyl ester, 0. 0316 gram of the colorless phenol ethyl ester, and 0. 1702 gram of the col- ored quinone ethyl ester in 40 per cent alcohol, sealed this solution in a tube, and heated at 60 for six hours.
