SYNONYMS Acrylic acid, 2-ethylhexy ester; Octyl Acrylate; 2-Propenoic acid, 2-ethylhexy ester; 1-Hexanol, 2-ethyl-, acrylate; 2-ethylhexyl 2-propenoate; 2-Ethylhexyl 2propenoate; 2-Ethylhexanol acrylate; 2-Ethyl-1-hexyl acrylate; 2-Ethylhexylester kyseliny akrylove; 2Ethylhexylpropenoate; 2-Propenoic acid octyl ester; EHA; Ethyl hexyl acrylate; Octyl acrylate; DERIVATION CLASSIFICATION PHYSICAL AND CHEMICAL PROPERTIES PHYSICAL STATE clear liquid MELTING POINT -90 C BOILING POINT 184 C SPECIFIC GRAVITY 0.82 0.888 SOLUBILITY IN WATER Insoluble SOLVENT SOLUBILITY Soluble in ether and alcohol pH VAPOR DENSITY 6.4 AUTOIGNITION 245 C NFPA RATINGS Health: 2; Flammability: 2; Instability: 2 REFRACTIVE INDEX FLASH POINT 82 C STABILITY The stability depends upon dissolved oxygen and MEHQ inhibitor. The presence of oxygen is necessary for inhibitor to prevent polymerization. APPLICATIONS Acrylic acid is the simplest unsaturated carboxylic acid which has double bond and carboxyl group in C3 one molecule with the formula CH2=CHCOOH. The vinyl group is attached to the carbonyl carbon directly. The systemic name is 2-propenoic acid. Acrylic acid has two reaction points or functional groups required for polymerization process. Purified (glacial) acrylic acid is a clear, colorless liquid with a characteristic acrid odor. It is miscible with water, alcohols and ethers. Acrylic acid is produced from C 3 refinery. Acrylic acid undergoes the typical reactions of a carboxylic acid and forms acrylic esters basic alkyl esters are methyl, butyl, ethyl acrylate, and 2-ethylhexyl acrylate. Acrylic acid and its esters undergo the reactions of the double bond which readily combine with themselves or other monomers (e.g amides, methacrylates, acrylonitrile, vinyl, styrene and butadiene) to form homopolymers or co-polymers which are used in the production of coatings, adhesives, elastomers, super absorbent polymers, flocculants, as well as fibres and plastics. Acrylate polymers show a wide range of properties dependent on the type of the monomers and reaction conditions.
