2-(Diethylamino)ethyl methacrylate Structural

What is 2-(Diethylamino)ethyl methacrylate?

Chemical properties

Colorless liquid

Physical properties

The pKa of (Diethylamino)ethyl methacrylate (DEAEMA) monomers is 8.8, while the pKa of these corresponding homopolymers is 7.5[1].

The Uses of 2-(Diethylamino)ethyl methacrylate

2-(Diethylamino)ethyl Methacrylate is used in preparation method and application of Hydrogel assembled self-adhesive material.

General Description

A clear light colored liquid. Insoluble in water and slightly denser than water. Flash point between 100-141°F. May be toxic by ingestion. Contact may severely irritate skin.

Air & Water Reactions

Flammable. Insoluble in water.

Reactivity Profile

An acrylic acid ester/amine. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. 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.

Health Hazard

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 or dilution water may cause pollution.

Flammability and Explosibility

Non flammable
