When it is heated to 300°C in the presence of oxygen, calcium phosphide becomes incandescent. [Pg.197]

In contact with dichlorine oxide, calcium phosphide heats up, causing explosive decomposition of the chlorinated compound. [Pg.197]

Phosphine is generated when phosphide salts (i.e., Aluminum phosphide Calcium phosphide Magnesium phosphide Magnesium aluminum phosphide Potassium phosphide Sodium phosphide Stannic phosphide Strontium phosphide Zinc phosphide) come into contact with water. [Pg.317]

Phosphine produced by the reaction of water on calcium phosphide always contains a quantity of the liquid hydrogen phosphide sufficient to make the gas spontaneously inflammable. Use of this property is made in the Holmes Light used at sea as a distress signal, and also as a marker at torpedo practice. [Pg.31]

For the laboratory preparation of phosphine, only a few of the many methods of formation are suitable. Among these the hydrolyses of calcium phosphide 8o- 3) jnagnesium phosphide aluminium phosphide zinc phos-... [Pg.17]

Together with phosphine, noticeable amounts of diphosphine and higher phosphines are formed by the hydrolysis of calcium phosphide thus, this reaction can be used for the preparation of such compounds. Quesnel reported that the formation of diphosphine can be avoided when aqueous hydrochloric acid is added drop-wise to a mixture of calcium phosphide and copper chloride (proportions by weight, CaaPj CuClj = 10 1) in boiling alcohol, for example, methanol, or in dioxane. [Pg.18]

When the calcium phosphide is formed by the reduction of Ca3(P04)2 with carbon, the phosphine obtained on hydrolysis usually contains up to 3% acetylene. [Pg.18]

Baudler and her co-workers have described in detail the preparation of larger quantities of phosphine by the hydrolysis of calcium phosphide. Higher phosphines (see page 51) formed simultaneously, are thermally decomposed to phosphorus, phosphine and hydrogen. It is noteworthy that, on storage in steel cylinders the diphosphine concentration in phosphine, originally less than 1%, increases. It is, even after several months, so small that the gas is not spontaneously inflammable in contact with air, whereas, after about one year, it is spontaneously inflammable. [Pg.18]

In the course of mass spectroscopic investigations of the hydrolysis products of calcium phosphide, Baudler and her co-workers could find no evidence for the existence of OPH3 as an oxidation product of PH3 In contrast, oxides of higher phosphines were observed, even when the hydrolysis of calcium phosphide was carried out with the strictest exclusion of oxygen. The... [Pg.23]

Diphosphine is formed by the hydrolysis of calcium phosphide 22.424,425, 428,429) gjgQ jy hydrolysis of other phosphides when these contain P—P linkages. Thus, for example, it is reported that the phosphine obtained by the hydrolysis of aluminium phosphide, which has been prepared from the elements with phosphorus in excess, is spontaneously inflammable. This is caused by the diphosphine formed at the same time. When the aluminium phosphide is prepared using stoichiometric or even excess amounts of aluminium, the formation of diphosphine is not observed on hydrolysis. The diphosphine, formed in large quantities by the hydrolysis of calcium phosphide, can be separated from the phosphine and hydrogen evolved simultaneously by cool-... [Pg.51]

This method was applied earlier to produce floating signal flares at sea. Floating cans of calcium phosphide were punctuated to admit sea water to generate phosphine, which ignited spontaneously to emit flares. The flares could not be extinguished by wind or water. [Pg.694]
