Beschreibung
Zusammenfassung:The present invention relates to a process for the preparation of 2-phenylphenol or its sodium salt, wherein dibenzofuran is reacted with metallic sodium in presence of a complexing agent, which is selected from the group consisting of aliphatic ethers, cycloaliphatic ethers, oligomeric aliphatic ethers, polymeric aliphatic ethers and thio ethers, and wherein the molar ratio of metallic sodium to dibenzofuran is less than 5:1. La présente invention concerne un procédé pour la préparation de 2-phénylphénol ou de son sel de sodium, dans lequel du dibenzofurane est mis à réagir avec du sodium métallique en présence d'un agent complexant, qui est choisi dans le groupe constitué d'éthers aliphatiques, d'éthers cycloaliphatiques, d'éthers aliphatiques oligomériques, d'éthers aliphatiques polymères et de thio éthers, et dans lequel le rapport molaire du sodium métallique au dibenzofurane est inférieur à 5:1.
