VERFAHREN ZUR HERSTELLUNG VON 4-PHENOXY-PHENOLEN |
| 摘要 |
Diazotization of 4-phenoxy-anilines in aqueous sulfuric acid of 60 to 75% strength and decomposition of the resulting diazonium compound in sulfuric acid of the same concentration range yields the corresponding phenols in high yields and quality. These phenols are intermediate for the corresponding 4-phenoxy-phenoxy alkane carboxylic acids which are pharmaceuticals capable of reducing the blood serum lipid level. |
