製造

チオホスホリルクロリド,チオ塩化リン(phosphorus thiochloride)ともいう．五塩化リンPCl5と五硫化二リンP2S5とを混合加熱すると得られる．工業的には，塩化アルミニウム触媒下での三塩化リンと硫黄との反応で得られる．

化学的特性

clear colourless to slightly yellowish liquid

使用

Thiophosphoryl chloride was used in the synthesis of O-ethyl dichlorothiophosphate.

一般的な説明

A colorless fuming liquid. Boiling point 257°F (125 °C). Irritates the eyes and mucous membranes. Corrosive to metals and tissue.

空気と水の反応

Fumes in air. Decomposes in water to form phosphoric acid and hydrochloric acid (hydrogen chloride). Both substances are corrosive to metal or tissue. Can also form hydrogen sulfide (H2S), a toxic flammable gas, in reaction with water [AAR 1991].

反応プロフィール

THIOPHOSPHORYL CHLORIDE is acidic. Incompatible with bases (including amines), with strong oxidizing agents, and with alcohols. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].

危険性

Strong irritant to skin and tissue.

健康ハザード

TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

火災危険

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.

安全性プロファイル

Poison by inhalation. Moderately toxic by ingestion. A corrosive irritant to skin, eyes, and mucous membranes. Explosive reaction with methylmagnesium iodlde. Explosive reaction with pentaerythritol + heat. Reacts with water or steam to produce toxic and corrosive fumes. When heated to decomposition it emits highly toxic fumes of POx, SOx, and Cl-.

純化方法

Possible impurities are PCl5, H3PO4, HCl and AlCl3. Gently mix it with H2O to avoid a heavy emulsion; the product decoulorises immediately and settles to the bottom layer. It is soluble in *C6H6 and CCl4. [Duval Inorg Synth IV 73 1953.] HARMFUL VAPOURS.
