Process for producing (meth) acrylic acid with reduced water content |
| abstract |
Disclosed herein is a method for purifying (meth) acrylic acid that provides a purified (meth) acrylic acid product containing a low aldehyde concentration and a moisture content of less than 0.2% by weight. One embodiment of the method includes distilling (meth) acrylic acid in the presence of an aldehyde treating compound. Another embodiment of the method includes distilling the crude (meth) acrylic acid in the presence of a reactive desiccant. The (meth) acrylic acid produced in this manner is particularly suitable for use in functional (meth) acrylic acid polymers such as superabsorbent polymers, binders, and ethylene- (M) AA copolymers. [Selection figure] None |
