Glacial acrylic acid

Polylacrylic Acid) and Poly(methacrylic Acid). Glacial acrylic acid and glacial meth-acrylic acid can be polymerized to produce water-soluble polymers having the following structures ... [Pg.1013]

Dimer formation, which is favored by increasing temperature, generally does not reduce the quaHty of acryhc acid for most applications. The term dimer includes higher oligomers formed by further addition reactions and present in low concentrations relative to the amount of dimer (3-acryloxypropionic acid). Glacial acrylic acid should be stored at 16—29°C to maintain high quaHty. [Pg.157]

Funk [3] prepared hydrogels with different pH values by reacting 90 parts of hydrophilic polymeric agents with glacial acrylic acid, water, and penta-erythritol triallyl with 10 parts of acrylic acid, sorbitan monococoate, and allyl methacrylate. [Pg.264]

The bottoms from the foreruns column are fed to the product column where the glacial acrylic acid of commerce is taken overhead Bottoms from the product column are stripped to recover acrylic acid values and the high boilers are burned The principal losses of acrylic acid in this process are to the aqueous raf finate and to the aqueous layer from the dehydration column and to dimerization of acrylic acid to 3-acryloxypropionic acid If necessary, the product column bottoms stripper may include provision for a short-contact-time cracker to crack tliis dimer back to acrylic acid (60).

The oxidation proceeds by the two-step catalytic process indicated above, without the isolation of the intermediate acrolein. Acrylic acid, obtained in high yield based on propylene, is isolated as an aqueous solution and purified by extraction and distillation. The principal impurities in the commercial monomer, termed glacial acrylic acid, that may affect subsequent polymerization reactions include acetaldehyde, acrolein, furfural, benzaldehyde, and acrylic acid dimer, 3-acryloxypropionic acid. Since these impurities are inhibitory in polymerization. [Pg.130]

CAUTION Inhibitor-free glacial acrylic acid or glacial methacrylic acid must be utilized within approximately 0.5-1.0 hr since uncontrolled polymerization of these monomers may be extremely violent, if not explosive. [Pg.301]
