2,2'-Дихлордиизопропиловый эфир

Описание

Bis-(2-chloroisopropyl) ether is a byproduct in the synthesis of ethylene and propylene glycol that has been found in municipal drinking water in the United States and waterways in the Netherlands where it is considered a persistent organic pollutant (POP). It is mutagenic in the S. typhimurium strains TA 1535 and TA 100 but lacks mutagenic activity in mice.

Химические свойства

Clear Colourless Oil

Физические свойства

Colorless to light brown oily liquid. Verschueren (1983) reported an odor threshold concentration of 320 ppb.

Использование

Bis(2-chloroisopropyl)ether is used as a sol vent for resins, waxes, and oils, and inorganic synthesis.

Общее описание

Colorless to light brown liquid. Odor threshold concentration 200 μg/L.

Реакции воздуха и воды

Subject to peroxidation in air. Insoluble in water.

Профиль реактивности

BIS(2-CHLOROISOPROPYL)ETHER oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979 p.151-154, 164].

Угроза здоровью

Bis(2-chloroisopropyl)ether exhibited moderately toxic and carcinogenic actions intest animals. The acute inhalation toxicity of this compound is considerably lowerthan those of bis(chloromethyl)ether and bis(chloroethyl)ether. Exposure to its vapors cancause irritation of the eyes and upper respiratory tract. Inhalation of 700 ppm of this com pound in air for 5 hours proved fatal to rats
The oral toxicity of bis(2-chloroisopropyl)ether in rats was found to be moderate, withan LD50 value of 240 mg/kg.
The compound is carcinogenic to animals.Although there is no evidence of its carcino genicity in humans, exposure may cause lungcancer.

Пожароопасность

BIS(2-CHLOROISOPROPYL)ETHER is combustible.

Возможный контакт

BCIE was previously used as a solvent and as an extractant. It may be formed as a by-product of propylene oxide production. It has been found in industrial waste water and in natural water.

Экологическая судьба

Biological. When bis(2-chloroisopropyl)ether (5 and 10 mg/L) was statically incubated in the dark at 25°C with yeast extract and settled domestic wastewater inoculum, complete biodegradation was achieved after 14 days (Tabak et al., 1981).
Chemical/Physical. Kollig (1993) reported that bis(2-chloroisopropyl)ether is subject to hydrolysis forming hydrochloric acid and the intermediate (2-hydroxy-isopropyl-2- chloroisopropyl)ether. The latter undergoes further hydrolysis yielding bis

Несовместимости

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. It may form dangerous peroxides upon standing; may explode when heated.

Утилизация отходов

Use special incinerator due to high HCl content, such as seagoing incinerator ships.
