PROCESS FOR STABILIZING ACRYLIC MONOMERS |
| abstract |
The invention relates to a process for stabilizing acrylic monomers in a distillation column, comprising the following steps: - addition of at least one stabilizer for acrylic monomers in a total concentration in the liquid phase of between 1 ppm and 5000 ppm; - injection of oxygen into the distillation column with an O2 / organic vapor molar ratio of between 0.01% and 1%; - addition of a metal sequestrant at a concentration in the liquid phase of between 0.1 ppm and 1000 ppm. |
