Sucrose has the advantage of being nonvolatile and nonhygroscopic. It is rather difficult to ignite and sometimes does not burn completely. It has a heat of combustion of about 3,950 calories, or only about half that of coal.
Page 161 - The absorptions should not be carried on at a temperature under 15°, for it has been observed that the potassium pyrogallate used for absorption is very much less active at a temperature under 7°. At a temperature of 15° or higher, the last trace of oxygen can be removed with certainty in the space of three minutes by shaking with the solution of potassium pyrogallate, while at lower temperatures the absorption...
Page 17 - B somewhat more than half full of boiled water and removing the flask A by slipping the tube a out of the rubber connection; then, by blowing into the rubber tube x, water is driven over from the flask B into the gas-collector C and the adjoining tubes, until the air is wholly displaced. The rubber tubes at b and g are now closed with pinchcocks. The flask A is then filled to the brim with distilled water, the stopper is inserted, water being thereby driven into the tube a, and the flask is again...
Page 166 - ... mentioned above. Copper powder made by reducing granular copper oxide with hydrogen may also be employed. If a hard glass tube, filled with this powder, be heated to red heat in a combustion furnace and the gases be then led through the tube, they can in this manner be completely freed from oxygen. A very active absorbent for oxygen is metallic copper in the form of little rolls of wire-gauze, immersed in a solution of ammonia and ammonium carbonate. It has long been known that many metals oxidise...
