Method for production of acrylic acid |
abstract |
The present invention comprises acrylic acid comprising the steps of (i) injecting a polymerization inhibitor into a stage other than the raw material supply stage and the reflux feed stage of the distillation column, and (ii) supplying acrylic acid recovered by pyrolysis of the oligomer to the dehydration process. It relates to a manufacturing method of. Therefore, according to this invention, acrylic acid can be used effectively and manufacturing efficiency can be improved. |
