titleOfInvention | Control of a process for the purification of (meth)acrylic acid using on-line, near ir analysis |
abstract | (Meth) acrylic acid (for example, acrylic acid), which comprises a step of subjecting at least one kind of (meth) acrylic acid precursor (for example, propylene) to a gas phase oxidation reaction and then conducting a first dewatering operation and then concentrating the dehydrated reaction product ), The improved method comprises controlling at least one of the content of water, the content of acetic acid and the content of (meth) acrylic acid in the reaction product during purification of the reaction product using on-line near-infrared spectroscopy . |
