"To break it down," said Calhoun bitterly, "I need aromatic olefines and some acetone, and acetic-acid radicals and methyl submolecular groups. To destroy it absolutely I need available unsaturated hydrocarbons they'll be gases! And it has to be kept from reforming as it's broken up, and I may need twenty different organic radicals available at the same time!
I asked, amazed at the skill with which he handled the blowpipe. "Not particularly when you know how to do it. In that tank is a porous asbestos packing saturated with acetone, under pressure. Thus I can carry acetylene safely, for it is dissolved, and the possibility of explosion is minimised.
However, if gun-cotton be dissolved in a suitable solvent, which is capable of being evaporated out, such as acetone, or acetate of ethyl, which are very volatile, it becomes, when thus dissolved and dried, a very hard, horn-like, amorphous substance, which may be used for a smokeless gunpowder.
The air inside the Med Ship grew pungent; stinging; strangling. Murgatroyd sneezed. Calhoun coughed. The grid operator seemed about to choke. But in the white fog Calhoun cried exultantly: "Aromatic olefines! Acetone! Acetic acid radicals and methyl submolecular groups! And smoke has unsaturated hydrocarbon gases.
Within a short time of the onset the urine may be found to contain acetone bodies, the breath may smell distinctly of acetone, and the child may become torpid and drowsy or agitated and restless. At times there may be exaggerated and deepened respiratory movements the so-called air hunger.
There is a fourth defect, at which humanity shudders, and which the laws ought to repress. Vinous liquors are more or less accompanied with acetone acid, or vinegar; but those proceeding from grain contain still more of this acid.
Electrolysis is also made use of in the manufacture of chloroform and iodoform, as the chlorine or iodine which is produced in the electrolytic cell is allowed to act upon the alcohol or acetone under such conditions that chloroform or iodoform is produced.

Kennedy tried to pick it off, but only succeeded in pulling off a very minute piece to which the flesh seemed to adhere. "That's queer," he whispered to me. "Water, naturally, has no effect on it, else it would have been washed off long before. Walter," he added, "just slip across the street quietly to the drug store and get me a piece of gauze soaked with acetone."
In that tank is a porous asbestos packing saturated with acetone, under pressure. Thus they carry acetylene safely, for it is dissolved and the possibility of explosion is minimized. "This mixing chamber, by which I am holding the torch, where the oxygen and acetylene mix, is also designed in such a way as to prevent a flash-back.
