外観
無色～ほとんど無色透明液体
化学的特性
clear liquid
使用
2-Ethylhexanal is used as an intermediate for chemical synthesis?and in the production of pharmaceuticals and odorous substances.
定義
ChEBI: A fatty aldehyde that is heptane in which one of the hydrogens at position 3 has been replaced by a formyl group. It is a metabolite of the plasticisers di-2-ethylhexyl phthalate (DEHP) and di-2-ethylhexyl adipate (DEHA).
一般的な説明
White liquid with a mild odor. Floats on water.
空気と水の反応
Spontaneously flammable in air. [Steele and Dugan, Chem. Eng. 66:160(1960)]. Insoluble in water.
反応プロフィール
2-ETHYLHEXANAL are aldehydes. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation.
危険性
Ignites in air.
健康ハザード
Inhalation may be irritating to mucous membrane; overexposure may cause dizziness and collapse. Ingestion causes irritation of mouth and stomach. Contact with eyes or skin causes irritation.
火災危険
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
安全性プロファイル
Moderately toxic by
ingestion and intraperitoneal routes. Mildly
toxic by inhalation and skin contact. An eye
and severe skin irritant. See also
ALDEHYDES. Dangerous fire hazard;
spontaneously flammable in air. To fight
fire, use foam, CO2, dry chemical, water
spray, mist, fog. Incompatible with oxidizing
materials. When heated to decomposition it
emits acrid and irritating fumes.
職業ばく露
It is used as a solvent extraction
chemical; in organic synthesis; perfume formulation,
disinfectant
輸送方法
UN1191 Octyl aldehydes, Hazard Class: 3;
Labels: 3-Flammable liquid
不和合性
May form explosive mixture with air.
Violent reaction with oxidizers. Incompatible with strong
acids; caustics, ammonia, amines. May ignite spontaneously when spilled on clothing or other absorbent materials.
May form unstable peroxides on contact with air; under
certain conditions ignites spontaneously with air.
廃棄物の処理
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.
