SAFETY PROFILE A poison. Flammable by spontaneous chemical reaction, air, moisture, or acid fumes may cause it to ignite. For explosion and disaster hazards, see SULFIDES. To fight fire, use CO2, dry chemical. Reacts violently with phosphorus(V) oxide. Mixtures with lead dioxide, potassium chlorate, or potassium nitrite explode when heated. Incompatible with CI2O, Ca(N03)2, Sr(N03)2, Ca(C103)2, Sr(C103)2, (C103)2. See also BARIUM COMPOUNDS (soluble) and SULFIDES.

Violent reaction with aluminum isopropoxide -f- heavy metal salts charcoal coal dimethylphenylphosphine hydrogen selenide lithium tetrahydroaluminate metals (e.g., potassium, sodium, lithium) metal oxides (e.g., cobalt oxide, iron oxide, lead oxide, lead hydroxide, manganese oxide, mercur oxide, nickel oxide) metal salts (e.g., calcium permanganate) methanol + phosphoric acid 4-methyl-2,4,6-triazatricyclo [5.2.2.0 ] undeca-8-ene-3,5-dione + potassium hydroxide a-phenylselenoketones phosphorus phosphorus (V) oxide tin(II) chloride unsaturated organic compounds. 

An interesting reduction of aromatic nitro compounds which uses glucose in an alkaline medium (equation 7) has received little attention. The advantages of this reaction include high yields, rapid rate and ease of product isolation from oxidation by-products. Other reagents which bring about the reduction of nitroanenes to azoxy compounds include potassium borohydride, sodium arsenate, phosphine and yellow phosphorus. Electrolytic methods have also been utilized. ... 

Compounds consisting of two elements, or of an element and a radical only, binary compounds, are designated by compound names made up of the name of the more electro-positive, followed by that of the more electro-negative, in which the termination ide has been substituted for tbe terminations ine. on, ogen, ygm, orus, turn, and ur. For example the compound of potassium and chlorine is called potassium chloride, that of potassium and oxygen, potassium oxide, that of potassium and phosphorus, potassium phosphide. 

FOSFURO de ZINC (Spanish) (1314-84-7) Combustible solid. Dust forms explosive mixture with air. Reacts with water, steam, moisture in air, acids, and/or heat, producing fumes of phosphorus, zinc oxides, flammable phosphine. Reacts violently with strong oxidizers, chlorine, fluorine, nitric acid, sulfuric acid, perchloric acid. Incompatible with carbon dioxide, halogenated compounds. Reacts with most common extinguishing agents. Forms heat-, friction-, and shock-sensitive explosive mixtures with potassium chlorate, potassium nitrate, sodium chlorate. In case of fire, use Class D extinguishers or smothering quantities of dry sand, crushed limestone, clay. 

Triethylphosphine oxide, (C2Hg)gPO, may be obtained by the following methods (1) By the oxidation of triethylphosphine by air, nitric acid or mercuric oxide. (2) By the action of potassium hydroxide on the product resulting from reaction between zinc diethyl and the compound CgHgOPClg. (3) One part of white phosphorus and 13 parts of ethyl iodide are heated together for 24 hours at 175° to 180° C., and the reaction mass then boiled with 97 per cent, alcohol until no more ethyl iodide is formed. The solution is then distilled vith 4 parts of potassium hydroxide. (4) Magnesium ethyl bromide is allowed to react with phosphorus oxychloride and the mixture then decomposed with dilute hydrochloric acid." (5) By heating the reaction product from zinc diethyl and phosphorus oxychloride with potassium hydroxide and a little water. ... 

Other elements which occur in organic compounds, such as phosphorus, arsenic, other non-metals, and metals in organic combination, are detected by destroying the organic material by oxidation (with nitric acid in a sealed tube or by fusion with potassium nitrate or sodium peroxide) and then applying the usual tests.
