Акролеин диэтил ацетал

Химические свойства

clear colorless liquid

Использование

Acrolein diethyl acetal is a reagent used for the synthesis of a variety of compounds, including cinnamaldehydes.

Общее описание

A colorless liquid with an agreeable odor. Very volatile. Flash point 70°F. Less dense than water. Vapors heavier than air. Used as a solvent and to make cosmetics.

Реакции воздуха и воды

Highly flammable. Soluble in water. Likely to slowly form peroxidized product when exposed to air. The formed peroxide is likely to be unstable.

Профиль реактивности

Ethers, such as DIETHOXYPROPENE, can act as bases. 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.

Угроза здоровью

Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control may cause pollution.

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

Mutation data reported. A flammable liquid. A dangerous fire hazard when exposed to heat, flame, or oxiduers. When heated to decomposition it emits acrid smoke and fumes.

Методы очистки

Add Na2CO3 (ca 3.5%) and distil it using an efficient column, or better use a spinning band column. [Witzemann et al. Org Synth Coll Vol II 17 1943, Beilstein 1 H 727, 1 I 378, 1 III 2960, 1 IV 3437.]
