CARBIDES CALCIUM CARBIDE

One example of an incendiary that seemed useful in the planning stage, but proved unnecessary after it was developed and tested, was a device to ignite oil slicks on water. In September 1942 the Navy Bureau of Ordnance asked the CWS to devise such a munition. The service modified existing incendiary bombs for the job, and also tried containers filled with calcium carbide (carbide reacts with water, producing acetylene which catches fire from the heat of reaction). [Pg.187]

The original method for the manufacture of ethyne, the action of water on calcium carbide, is still of very great importance, but newer methods include the pyrolysis of the lower paraffins in the presence of steam, the partial oxidation of natural gas (methane) and the cracking of hydrocarbons in an electric arc. [Pg.169]

Acetylene can be readily obtained by the action of water on calcium carbide since, however, commercial calcium carbide contains traces of calcium... [Pg.86]

Drying agents may be divided broadly into (a) those which combine with water reversibly and (6) tho.se which react chemically with water by a non-revcrsible process giving rise to a new water-free compound. Sodium, calcium carbide and phosphorus peiitoxide belong to the latter class and wih be discussed in Section 11,39. [Pg.39]

Acetylene was discovered m 1836 by Edmund Davy and characterized by the French chemist P E M Berthelot m 1862 It did not command much attention until its large scale preparation from calcium carbide m the last decade of the nineteenth century stim ulated interest m industrial applications In the first stage of that synthesis limestone and coke a material rich m elemental carbon obtained from coal are heated m an electric furnace to form calcium carbide... [Pg.363]

Calcium carbide is the calcium salt of the doubly negative carbide ion (C=C ) Car bide ion is strongly basic and reacts with water to form acetylene... [Pg.363]
