| titleOfInvention | Stabilized Acrylic Acid Composition |
| abstract | The present invention provides a stabilized acrylic acid composition which inhibits the polymerization of acrylic acid not only during the transport and storage of acrylic acid, but also during the distillation process for purification or separation. The composition of the present invention comprises three components: (A) acrylic acid, (B) stable nitroxy radicals, for example nitroxy radicals 4-hydroxyl-2,2,6,6-tetramethyl-1- Piperidinyl octa (CAS Registry No. 2226-96-2) (HTEMPO), and (C) dihetero substituted benzene compounds with at least one movable hydrogen, such as mono-methyl ether of hydroquinone (MEHQ) and In the same quinone derivative, distillation process, transport and storage, components (B) and (C) are present in the amount of polymerization inhibition. At the time of a distillation process, it is preferable to add oxygen (D) with component (B) and (C). |
