| use | 1, 3-cyclohexyldione is an intermediate of herbicides sulfoxone and nitrosulfonone. Used as a pharmaceutical intermediate; used in organic synthesis. Used in organic synthesis. HPLC labeling |
| Production method | The preparation method is to use resorcinol to carry out hydrogenation reaction in the presence of Raney nickel catalyst to obtain the product. Put resorcinol and sodium hydroxide solution into a autoclave, add nickel catalyst, and react with hydrogen at 50 ℃, 70-100 atmosphere for 10-12h. Then the temperature is lowered, the pressure is relieved, the catalyst is filtered out, the filtrate is acidified with concentrated hydrochloric acid, cooled to 0 ℃, and the crystals are filtered out, that is, crude 1, 3-cyclohexanedione. The crude product is recrystallized with hot benzene to obtain the finished product. |
