Acrylic Acid Production and Manufacturing Process | ICIS

Acrylic Acid Production and Manufacturing Process | ICIS

Acrylic acid from the primary oxidation can be recovered while the acrolein is fed to a second step to make acrylic acid. Purification can be carried out by azeotropic distillation. Korea's LG Chem has developed a process that employs a new reactor design and purification technique. The reaction temperature is claimed to be easier to control .

Allergic effects of the residual monomer used in denture .

It has been reported that self-cured/auto-polymerized acrylic resins leach out higher quantities of residual monomer than heat-cured denture base resins.[29,30,31,32] Baker et al.,[] during their investigation found greater quantities of methyl methacrylate (MMA) in saliva of the individuals who were wearing dentures made up of self-cured/auto-polymerized denture base resins.

Process Designs for Converting Propylene Glycol to Acrylic .

Acrylic acid produced from monopropylene glycol is a good candidate to become a cost-competitive and sustainable platform chemical. The propylene glycol price is expected to drop due to the expected abundance of propylene glycol as a sugar hydrogenolysis byproduct, which is required to make the conversion to acrylic acid cost-competitive.

Acrylic reactor runaway and explosion accident analysis .

The immediate cause turned out to be a vapor cloud explosion and the blast mass was estimated to be equivalent to 1000 kg of TNT. However, the original cause was found to be a runaway reaction of a 6-ton reactor that contained methyl acrylate, methyl alcohol, acrylonitrile, isopropyl alcohol, acrylic acid, methacrylic acid, and benzoyl peroxide.
