iso-Butyl Acrylate (IBA)

iso-Butyl Acrylate (IBA) is an ester of Acrylic acid and is used as a raw material component in the synthesis of polymers. The ester is a monofunctional monomer consisting of a methacrylate group with a characteristic high reactivity and a cyclic hydrophobic group. It forms homopolymers and copolymers. Its copolymers can be obtained from acrylic acid and its salts, amides, and esters, etc.

iso-Butyl Acrylate (IBA) is a very useful starting material for chemical synthesis since it easily undergoes addition reactions with a wide spectrum of organic and inorganic compounds.

In order to prevent polymerization, iso-Butyl Acrylate (IBA) must always be stored under air, and never under inert gases. The presence of oxygen is required for the stabilizer to function effectively. It has to contain a stabilizer and the storage temperature must not exceed 35 °C. Under these conditions, a storage stability of one year can be expected upon delivery. In order to minimize the likelihood of overstorage, the storage procedure should strictly follow the “first-in-first-out” principle. For extended storage periods over 4 weeks it is advisable to replenish the dissolved oxygen content. Storage tanks and pipes should be made of stainless steel or aluminum. Carbon steel is also acceptable, although the formation of rust may be a problem with product quality (color). Iron(III)-ions have been shown to be a weak polymerization initiator. If carbon steel is to be used, special procedures should be used to prepare the tank for use. Regulations for the storage of flammable liquids mst be observed (explosion-proof electrical equipment, ventedtanks with flame arresters etc.). Storage tanks, pumps and pipes should be earthed.
