Excerpt from American Chemical Journal, Vol. 46: July December, 1911A small portion of the colorless crystals was placed in a platinum boat and heated to 110° in a current of carbon dioxide in the apparatus elsewhere described.1 The out ¿owing carbon dioxide was passed through Hugershoff gas wash bottles containing distilled water. The water was then found to contain acetone, as shown by its odor, by the forma tion of large amounts Of iodoform on treatment with am monium hydroxide and iodine - potassium iodide solution, and finally by the formation of acetone phenylhydrazone on treatment with phenylhydrazine hydrochloride and sodium acetate. The substance in the boat came to constant weight after seven hours' heating at 110° and there was no further loss on heating for one hour at The loss of weight was per cent. And the fact that no moisture condensed on the cold part Of the tube indicated that this loss was due entirely to acetone, past experience having shown that even per cent. Of water in a compound leads to the deposition Of moisture on this part of the tube. This loss of weight agrees closely with that required by the formula c20h807c14. 2ch3coch3 for which the calculated loss (acetone) is per centf' The chlorine content of the original white crystals is also in accord with the above formula.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
