Method for producing phloroglucin |
| abstract |
In a method for producing phloroglucin by a decomposition of 1,3,5-triisopropylbenzene trihydroperoxide (hereinafter referred to as THPO), a method for producing phloroglucin wherein an acid catalytic decomposition is carried out under the condition that: (1) at least one member selected from the group consisting of perchloric acid, sulfuric anhydride and boron trifluoride be used as a catalyst, (2) the amount of the catalyst above in the reaction solution be 1 to 100 ppm, (3) the water content in the reaction solution be not more than 2% by weight, and (4) the total amount of the carbinol group of carbinols (having a structure in which part or all of the three hydroperoxy groups of THPO have been replaced by hydroxyl groups) contaminating the raw material for reaction be not more than 1/5 equivalent based on THPO. The phloroglucin is useful as a starting material of medicines and photosensitizers. |
