| Use | an important intermediate for the synthesis of Indinavir (Indinavir). 1-indanone is used in organic synthesis. |
| production method | dry hydrogen chloride was passed through the freshly distilled indene at a temperature of 5-10 °c, 8-10H was required for the reaction, and the reaction product was distilled under reduced pressure, and 90-103(1.73kPa) was collected to obtain α-chloroindene. This was oxidized with chromium trioxide in glacial acetic acid at a temperature of 35-40 °c to produce dihydro-1-indanone. The yield ranged from 50% to 60%. |
| autoignition temperature | 525°C |
