Control of a process for the purification of (meth)acrylic acid using on-line, near ir analysis and a coupled, two-tower system for the dehydration of a reaction product obtained from the gas-phase oxidation of at least one (meth)acrylic acid precursor

An improved process for the manufacture of technical grade (meth)acrylic acid, e.g., acrylic acid, the process comprising producing a hydrated reaction product from the gas-phase oxidation of at least one (meth)acrylic acid precursor, e.g., propylene, followed by first dehydrating and then concentra...
