Isobutyl acrylic acid or 2-methylpropyl acrylate is a chemical compound and the ester of acrylic acid .

Extraction and presentation

Isobutyl acrylic ester can be obtained by esterifying acrylic acid with isobutyl alcohol .

properties

Acrylic acid isobutyl ester is a flammable, little volatile, colorless liquid with an ester-like odor that is sparingly soluble in water. The technical product often contains monomethyl ether hydroquinone as a polymerization inhibitor. It has a viscosity of 0.8 mPas at 20 ° C and can form homopolymers and copolymers.

use

Isobutyl acrylic ester is used in formulations for paints, adhesives and PE polymers. Due to the higher glass transition temperature and branching compared to n -butyl acrylate , z. B. improves the water resistance of paints.

safety instructions

The vapors of isobutyl acrylate can form an explosive mixture with air ( flash point 29 ° C, ignition temperature 350 ° C). It decomposes when heated, which can produce irritating vapors and gases.
