CI; 0.00793 gm-Br; 0.01259 gm. I. 1 L. Gattermann: Ann. d. Chem., ccclvii, p. 356, 1907. r separated with chloroform of crystallization, and was therefore boiled with dry acetone. As it was still found to be impure, it was taken up in hot absolute alcohol and filtered rapidly from the undissolved residue. 5 grams of the salt separated on cooling. It melted at 155-60, dissolved readily in water, and gave a pink color with sulphuric acid. 0.1779 gm. of substance required 5.15 cc. AgNO, Solution I. Calculated for C„HMON.Br: Br = 22.49 per cent. Found: Br = 22.92 per cent. p-Methylphenoxyethylhexamethylenetetraminium Bromide.--The salt was obtained in the same way as the ortho isomer. Yield: 33 grams, containing chloroform of crystallization. After boiling with dry acetone, the salt melted at 1760. It was somewhat more readily soluble in water than the ortho isomer, and gave no color with sulphuric acid. 0.2071 gm. of substance required 5.8 cc. AgNO, Solution I. Calculated for CmHmOIBr: Br = 22.49 per cent. Found: Br = 22.21 per cent. a-Naphthyl Bromoethyl Ether (a-Naphthoxyethyl Bromide).--This was prepared in the same way as m-cresoxyethyl bromide. Yield: 11o grams, boiling at 154-6 at 0.8 mm., from 145 grams of ot-naphthol, 80 grams of 50 per cent aqueous sodium hydroxide in 250 cc. of absolute alcohol, and 500 grams of ethylene bromide. The boiling point was unchanged by a subsequent distillation. A few drops of the substance, on long standing in a freezing mixture, with occasional rubbing, yielded crystals which caused the solidification of the entire distillate. Recrystallized from ligroin with the aid of a free...
