디에틸아미노에탄올 C화학적 특성, 용도, 생산
화학적 성질
Colorless liquid with a nauseating, weak, ammonia odor; hygroscopic; very soluble in water; soluble in alcohol, ether acetone, benzene, and petroleum ether.물리적 성질
Colorless, hygroscopic liquid with a nauseating, ammonia-like odor. Experimentally determined detection and recognition odor threshold concentrations were 50 μg/m3 (11 ppbv) and 190 μg/m3 (40 ppbv), respectively (Hellman and Small, 1974).용도
Water-soluble salts; textile softeners; antirust formulations; fatty acid derivatives; pharmaceuticals; curing agent for resins; emulsifying agents in acid media; organic synthesis.생산 방법
2-Diethylaminoethanol (DEAE) is a tertiary amine produced by reaction of ethylene oxide or ethylene chlorhydrin and diethylamine (RTECS 1988). Itokazu (1987) has modified this process for manufacture of DEAE without eventual discoloration. Production in this country exceeds 2866 pounds per year (HSDB 1988).정의
ChEBI: 2-diethylaminoethanol is a member of the class of ethanolamines that is aminoethanol in which the hydrogens of the amino group are replaced by ethyl groups. It is a member of ethanolamines, a tertiary amino compound and a primary alcohol. It derives from an ethanolamine. It derives from a hydride of a triethylamine.일반 설명
A colorless liquid. Flash point 103-140°F. Less dense than water . Vapors heavier than air. Produces toxic oxides of nitrogen during combustion. Causes burns to the skin, eyes and mucous membranes.공기와 물의 반응
Flammable. Soluble in water. Diethylaminoethanol is sensitive to moisture. Slowly hydrolyzes.반응 프로필
Diethylaminoethanol is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Diethylaminoethanol can react with strong oxidizers and acids.건강위험
INHALATION: Irritation of mucous membranes.EYES: Corrosive, causes intense pain.
SKIN: Severe irritation. May cause allergic skin reaction.
INGESTION: Gastrointestinal irritation.
Breathing Diethylaminoethanol can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath.
공업 용도
Diethylaminoethanol(DEAE) is used in the pharmaceutical industry for the manufacture of the local anesthetics procaine and chloroquine; and in the chemical industry for the manufacture of water-soluble salts, fatty-acid derivatives, derivatives containing tertiary amine groups, emulsifiers, special soaps, cosmetics and textiles and fibers (HSDB 1988). It also is used in chromatography in chemistry and biochemistry laboratories (DEAE is useful as an ion-exchange matrix; DEAE-cellulose columns are used for purification of proteins and DNA, and DEAE-silica for phospholipid separations). In other industries DEAE is used in some antirust compositions and in textile softeners (Hawley 1977; HSDB 1988). It is also used widely as a steam additive in large buildings requiring humidifiers.Safety
There is a lack of data regarding human toxicity of Diethylaminoethanol. The greatest industrial hazard however, is thought to be to the eyes from contact with the fluid, which is comparable in severity to ammonium hydroxide as an eye irritant (ACGIH 1980).Diethylaminoethanol(DEAE) is permitted by the U.S. Food and Drug Administration for some applications as a food additive. Applications include protective coatings for fresh fruits and vegetables, and as an additive in steam which directly contacts food products (excluding milk products). The National Research Council Committee on Toxicology (NRC 1983) has concluded that data on long-term, low-level airborne exposures of animals to DEAE for extrapolation to human health risks are severely lacking. This, combined with the lack of data concerning the concentrations of DEAE in humidified buildings did not allow sufficient information to set guidelines for long-term exposures or estimate the health risks from such exposures. The NRC was able to make some general recommendations based on the assumption that the nitrosation reactions (below) may occur, and that the amine should be considered as hazardous as the nitroso compound formed from it.
Carcinogenicity
DEAE was not mutagenic or clastogenic in a variety of in vitro and in vivo assays.The 2003 ACGIH threshold limit valuetime- weighted average (TLV-TWA) for 2- diethylaminoethanol is 2 ppm (9.6mg/m3) with a notation for skin absorption.
환경귀착
DEAE, when compared with other amino alcohols, was observed to be biologically undecomposable in an experiment using activated sludge (HSDB 1988).신진 대사
The absorption of DEAE (administered orally as DEAE acid malate or 'Cerebrol') in healthy adult rats is very rapid, reaching a peak plasma level in 30 min (Bismut et al 1986). The biological half-life is 3.5 h with 39% of the excreted product appearing in the urine after 48 h (Bismut et al 1986). In an earlier study, Schulte et al (1972) demonstrated that in rats, following a single oral dose, excretion occurs mainly through the kidneys with 37-59% being eliminated in the first 24 h. After 48 h, elimination was independent of dose. The brain and spinal cord showed the highest concentration after 7 d. Metabolites produced were observed to be diethylaminoethanol N-oxide, diethylaminoacetic acid, and ethylaminoethanol.디에틸아미노에탄올 준비 용품 및 원자재
