化学的特性

Pentaborane is a colorless, volatile liquid. Unpleasant, sweetish odor, like sour milk. The Odor Threshold is 0.8 ppm.

一般的な説明

A clear colorless liquid with a pungent odor like sour milk, and flammable.It is corrosive to natural rubber, some synthetic rubber, some greases, and some lubricants and gives off irritating or toxic fumes (or gases) in a fire. It reacts violently with fire. Pentaboron nonahydride incompatible with strong oxidants such as chromium anhydride, chlorate and potassium permanganate, and other contacts. Vapors toxic both under prolonged exposure to low concentrations and short exposure to high concentrations. Density 0.61 g / cm3. Under prolonged exposure to intense heat the containers may rupture violently and rocket.

空気と水の反応

Highly flammable. May ignite spontaneously in air [Merck 11th ed. 1989]. Slowly decomposes in water.

反応プロフィール

Pentaborane is an extremely reactive reducing agent. Can ignite spontaneously in contact with air and many other materials. Reactions with oxygen are often violently explosive. Reacts with ammonia to form a diammoniate. Is stabilized by the formation of complexes with N, O, P, or S. Is stable in hydrocarbon solvents, but forms shock sensitive solutions in most carbonyl containing solvents.

健康ハザード

May cause death or permanent injury after very short exposure to small quantities.

火災危険

Ignites spontaneously in air. Reacts violently with halogenated extinguishing agents. Boron hydrides present considerable fire and explosion hazard. They undergo explosive reaction with most oxidizing agents, including halogenated hydrocarbons. Fires tend to reignite. On decomposition, Pentaborane emits toxic fumes and can react vigorously with oxidizing materials. Avoid dimethyl sulfoxide, water, most oxidizing agents (including halogenated hydrocarbons). Avoid direct sunlight and sources of ignition, decomposes very slowly at 302. Hazardous polymerization may not occur.

安全性プロファイル

Poison by inhalation and intraperitoneal routes. Dangerous fire hazard by chemical reaction; spontaneously flammable in air. Dangerous explosion hazard. To fight fire, use special fire-fighting materials; water is not effective; reacts violently with halogenated extinguishing agents. Get instructions from supplier. Explosive reaction with oxygen. Forms shock-sensitive solutions in solvents containing carbonyl, ether, or ester functions; or halogens. Incompatible with dimethyl sulfoxide. Upon decomposition it emits toxic fumes of B. See also BORANES and BORON COMPOUNDS

職業ばく露

Pentaborane is used in rocket propellants and in gasoline additives.

輸送方法

UN1380 Pentaborane, Hazard Class: 4.2; Labels: 4.2-Spontaneously combustible material, 6.1-Poisonous materials. Inhalation Hazard Zone A.

不和合性

Pentaborane is an extremely reactive reducing agent. It can ignite spontaneously in contact with air and many other materials. Reactions with oxygen are often violently explosive. Reacts with ammonia to form a diammoniate. Reacts on contact with water, oxidizers, halogens, including halogenated hydrocarbons. May sel-heat and ignite spontaneously in moist air, decomposes @ 150C. Hydrolyzes slowly with heat in water to form boric acid. Contact with solvents, such as ketones, ethers and esters form shock-sensitive compounds. Pentaborane is stable in hydrocarbon solvents, but forms shock sensitive solutions in most carbonyl containing solvents. Corrosive to natural rubber, some synthetic rubbers and to some lubricants. Avoid dimethyl sulfoxide, direct sunlight and sources of ignition.

廃棄物の処理

Incineration with aqueous scrubbing of exhaust gases to remove B2O3 particulates.
