the simplest ketone; a highly inflammable liquid widely used as an organic solvent and as material for making plastics

A colorless liquid used as a solvent and an antiseptic. It is one of the ketone bodies produced during ketoacidosis.

1. A substance, CO. (CH3)2, found in the urine and blood in diabetes; it is the cause of the peculiar odor in that disease. 2. Acetonum.

Methyl acetyl; naphtha; pyro-acetic acid; produced by fermentation of organic matter.

A light inflammable liquid.

Pyro-acetic spirit.

A limpid, colourless liquid, having a peculiarly penetrating and slightly empyreumatic odour. Its density in the liquid state, is almost the same as that of alcohol, 0.7921. Its taste is disagreeable, and analogous to that of peppermint. It is miscible in all proportions with water, alcohol, and ether. It may be prepared by distilling a mixture of two parts of crystallized acetate of lead and one part of quicklime in a salt-glaze jar (gray-beard,) the lower part of the jar being coated with fire-clay; and a bent glass tube, half an inch in diameter, adapted to the mouth by a cork, so as to form a distillatory apparatus. The jar is supported on the mouth of a small furnace, by which the lower part only is heated to redness, and the vapours are conducted into a Liebig's condenser. The product is repeatedly redistilled from quicklime, until its boiling point is constant at 132. It has been brought forward as a remedy in phthisis pulmonalis; but evidently with unfounded pretensions. It is an excitant, and may be serviceable in chronic bronchitis. The dose is ten to forty drops three times a day, diluted with water.

Colorless inflammable liquid, C3H6O, or dimethyl ketone; anesthetic and anthelmintic.

Syn.: pyro-acetic spirit, acetylmethyl, dimethyl ketone. A colorless, mobile liquid, of pleasant odor, produced by the destructive distillation of acetates (whence the name pyro-acetic spirit), and of sugar, cellulose, and various organic compounds: CH3.CO.CH3. It has been found in small quantities in normal urine, [von Jaksch]; in larger amounts in diabetic urine. The fruitlike odor of the breath in diabetic patients is supposed to be due to a. A feeble anesthetic action has been attributed to it. Circulating in the blood, it gives rise to acetonemia.
