Химические свойства
clear colorless liquid
Использование
Diglycidyl ether is significant only because it is a possible
trace component of epoxy compounds derived from
epichlorohydrin.
Общее описание
Colorless liquid with a pronounced irritating odor. Used as a reactive dilutent for epoxy resin , as a chemical intermediate, as a stabilizer of chlorinated organic compounds, and as a textile-treating agent.
Реакции воздуха и воды
Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154, 164].
Профиль реактивности
Epoxides, such as DIGLYCIDYL ETHER, are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts.
Угроза здоровью
DIGLYCIDYL ETHER can cause death or permanent injury via oral and inhalation routes during exposure that comes from normal use. It is incapacitating and poisonous and requires special handling. It can cause considerable discomfort by the dermal route.
Пожароопасность
(Non-Specific -- Poison, Flammable Liquid, n.o.s.) May be ignited by heat, sparks, or flames. Container may explode in heat of fire. Vapor explosion and poison hazard indoors, outdoors or in sewers. Avoid strong oxidizers.
Профиль безопасности
Suspected carcinogen
with experimental tumorigenic data. Poison
by ingestion, inhalation, and intravenous
routes. Moderately toxic by skin contact. A
severe eye and skin irritant. Mutation data
reported. Chronic exposure can cause bone
marrow depression. When heated to
decomposition it emits acrid smoke and
fumes. See also ETHERS.
Канцерогенность
In mice, diglycidyl ether has
been shown to produce epithelioma following repeated
skin application. A total dose of 100 mg produced these
tumors in 4 of 20 animals; a dose of 33 mg produced only
1/20 .
