2-этилгексанал

Химические свойства

clear liquid

Использование

2-Ethylhexanal is used as an intermediate for chemical synthesis?and in the production of pharmaceuticals and odorous substances.

Определение

ChEBI: A fatty aldehyde that is heptane in which one of the hydrogens at position 3 has been replaced by a formyl group.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).

Общее описание

White liquid with a mild odor. Floats on water.

Реакции воздуха и воды

Spontaneously flammable in air. [Steele and Dugan, Chem. Eng. 66:160(1960)]. Insoluble in water.

Профиль реактивности

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.

Опасность

Ignites in air.

Угроза здоровью

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.

Пожароопасность

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.

Профиль безопасности

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.

Возможный контакт

It is used as a solvent extraction chemical; in organic synthesis; perfume formulation, disinfectant

UN1191 Octyl aldehydes, Hazard Class: 3; Labels: 3-Flammable liquid

Несовместимости

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.

Утилизация отходов

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.
