| titleOfInvention | Method of refining dihydroxyaryl compound |
| abstract | Purified dihydroxyaryl compound, such as catechol, having high purity and very low metal content, evaporates the starting dihydroxyaryl compound in the distillation column, condenses the vapor part in a condenser connected to the top outlet of the column, and condenses the condensed part. Is collected by collecting condensate from a condenser through a conduit into a storage tank, the condenser and optionally the conduit and / or storage tank having an internal surface formed from a metallic material containing at least 25% by weight of nickel, condensed dihydroxyaryl compound The part comes into contact with a specific nickel (25% or more) containing metal inner surface. |
