Process for manufacturing reduced water content (meth) acrylic acid |
| abstract |
A method is provided herein for purifying (meth)acrylic acid to provide a purified (meth)acrylic acid product having a low aldehyde concentration and not more than 0.2 wt% water. One embodiment of the method includes distilling (metn)acrylic acid in the presence of an aldehyde treating compound. Another embodiment of the method includes also distilling crude (meht)acrylic acid in the presence of a reactive drying agent. (Meth) acrylic acid produced in this manner is especially suitable for use in specialty (meth)acrylic acid polymers, such as for example superabsorbent polymers, binders, and ethylene-(M)AA copolymers. |
