Not illustrated. 1894 Excerpt: ...tube for four or five hours at 100 with either acetyl chloride or acetic anhydride, preferably the former. It is best to use a slight excess of acetyl chloride, and after the heating is finished to decompose the excess by means of water. The diacetate is easily recrystallized from alcohol, and was identified by its melting point, 108. After boiling tribromresorcinediacetate with water for twenty-four hours, the water was slightly pink in color, and gave a feeble tost for bromides with argentic nitrate. This is due, no doubt, to the fact that water at 100 saponifies a small part of the diacetate, yielding tribromresorcine, which in its turn is acted upon by the boiling water, as before noted. In the hope of avoiding this saponification, a sealed tube containing the diacetate was heated over night at 157 with ordinary acetic acid, but the saponification was not prevented, for the result was the same as if the free tribromresorcine had been heated with water alone to that temperature. Sodic ethylate in alcoholic solution when warmed with tribromresorcinediacetate deposited a precipitate which when filtered off soon turned black. This body was undoubtedly the decomposition product of the sodium salt of tribromresorciue. On account of the readiness, therefore, with which the diacetate was saponified, it was not worth while to carry on this line of investigation further. Tribromnitroresorcinediacetate, C3(N02)Br3(OC2H30)2. The diacetate of tribromresorcine when added to an excess of fuming nitric acid immediately dissolved, and after standing several minutes the solution became very warm and began to boil, the body in solution becoming completely oxidized; but if just before the oxidation took place, when the solution was already hot, it was poured into an excess...
