| titleOfInvention | Process for producing purified (meth) acrylic acid |
| abstract | The present invention reduces the corrosion of distillation equipment during azeotropic distillation of (meth) acrylic acid in the presence of dissolved copper by supplying aqueous (meth) acrylic acid having up to 0.1% by weight of formaldehyde relative to the total weight of aqueous (meth) acrylic acid. It's about making things happen. The source of copper may be, for example, a copper-based polymerization inhibitor added to aqueous (meth) acrylic acid and / or distillation equipment.n n n n Aqueous (meth) acrylic acid, reduced corrosion, copper-based polymerization inhibitor |
