| titleOfInvention | Reduced water content (meth) acrylic acid production process |
| abstract | A method of purifying (meth) acrylic acid is provided which provides a purified (meth) acrylic acid product having a low aldehyde concentration and water of 0.2 wt% or less. One embodiment of the method of the present invention comprises purifying (meth) acrylic acid in the presence of an aldehyde treating compound. Another embodiment of the process of the present invention also includes distilling crude (meth) acrylic acid in the presence of a reactive desiccant. The (meth) acrylic acid produced in this way is particularly suitable for use in special (meth) acrylic acid polymers such as, for example, superabsorbent polymers, binders, and ethylene- (M) AA copolymers.n n n n Acrylic acid, tablets, superabsorbent polymers, binders, aldehydes |
