n-부틸 글리시딜 에테르 C화학적 특성, 용도, 생산
개요
n-Butyl glycidyl ether is a reactive diluent used to
reduce viscosity of epoxy res ins Bisphenol A type.
화학적 성질
n-Butyl glycidyl ether is a colorless liquid with
slight irritating odor.
용도
Uses include the roles of viscosity-reducing agent for easier
handling of conventional epoxy resins, acid acceptor for
stabilizing chlorinated solvents, and chemical intermediate.
Some curing agents may produce hazardous polymerizations
in large quantities.
생산 방법
n-Butyl glycidyl ether (BGE) is made by the condensation
of n-butyl alcohol and epichlorohydrin with subsequent
dehydrochlorination with caustic to form the epoxy ring.
일반 설명
Colorless to pale yellow liquid with a strong, slightly unpleasant odor. Flash point approximately 164°F. Denser than water. Vapors are heavier than air. Vapors may irritate the nose, throat and respiratory tract. Ingestion or inhalation may cause central nervous system depression. Liquid contact may severely irritate the eyes and skin. Prolonged contact with the skin may cause defatting and drying.
공기와 물의 반응
Highly flammable. Butyl glycidyl ether may be sensitive to prolonged exposure to air, may form explosive peroxide in contact with air.
반응 프로필
Butyl glycidyl ether, an ether, can act as a base. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.
위험도
A mild skin and eye irritant. Sensitization
and reproduction effects.
건강위험
Exposure can cause mild irritation of skin, eyes, nose, and respiratory tract. Chronic exposure may cause inflammation and sensitization of the skin.
색상 색인 번호
A reactive diluent used to reduce viscosity of epoxy
resins Bisphenol A type.
Safety Profile
Suspected Carcinogen.
Moderately toxic by ingestion, skin contact,
and inuaperitoneal routes. Mildly toxic by
inhalation. An experimental teratogen.
Mutation data reported. A sktn and severe
eye irritant. See also ETHERS. When heated
to decomposition it emits acrid and irritating
fumes.
잠재적 노출
NIOSH has estimated human exposures @ 18,000. Used as reactive diluent for epoxy resins,
flooring, laminating, and electrical; and as a stabilizer,
viscosity-reducing agent, as acid acceptor for solvents; and
as a chemical intermediate
Carcinogenicity
BGE was mutagenic in bacterial assays,
and DNA damage was induced in human cells
in vitro.

비 호환성
May form explosive mixture with air.
Air and light form unstable and explosive peroxides.
Contact with strong oxidizers may cause fire and explosions. Contact with strong caustics may cause polymerization. Attacks some plastics and rubber
폐기물 처리
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be
observed.
