Method for producing high purity methacrylic acid |
| abstract |
The present invention provides a method for producing high purity glacial methacrylic acid ("HPMAA") of substantially pure, specifically 99% or more pure and 0.05% or less water content. The improved process includes providing a crude MAA stream in a continuous distillation step and purifying the crude methacrylic acid stream. |
