Butyl acrylate
Formula: CH2=CHCOO(CH2)3CH3
CAS No.: 141-32-2
Physical state: Clear liquid
Hazard class: 3
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.
Alkyl acrylates are clear, volatile liquid; Slightly soluble in water and complete soluble in alcohols, ethers and almost organic solvents; Acrylate esters containing a double bond and functional carboxyl group are used chiefly as a monomer or co-monomer in making acrylic and modacrylic fibres. It is used in formulating paints and dispersions for paints, inks, and adhesives. It is used in making cleaning products, antioxidant agents, amphoteric surfactants. It is used in making aqueous resins and dispersions for textiles and papers. Methyl acrylate also used in making vitamin B1.
