BENZO[CD]INDOL-2(1H)-ONE - Upstream Downstream Industry
| Raw Materials | 1,8-Naphthalimide |
BENZO[CD]INDOL-2(1H)-ONE - Reference Information
| LogP | 2.5 at 24℃ and pH6.6 |
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Uses | Intermediates for the synthesis of vat dyes and organic pigments Dye intermediates Photoinduced Fries rearrangement reaction reagent; Preparation of powerful anti-tumor agent reagents; Used for the synthesis of thymidylate synthase inhibitors |
| production method | obtained by rearranging 1,8-naphthalimide. Add water, sodium hydroxide solution and caustic potassium solution in the reaction pot, add sodium hypochlorite and diffusion agent NNO while stirring, add 1,8-naphthalimide at 30 ℃, and keep the temperature at 28-30 ℃ for 2.5h. Maintain excess sodium hypochlorite during the reaction. At the end of heat preservation, excess sodium hypochlorite was eliminated with sodium sulfite, and adjusted to 9.5-10 with hydrochloric acid. The unreacted naphthalene diimide was filtered out, the filtrate was below 40 ℃, and the pH was 2-3 with hydrochloric acid. Heat to 80-85 ℃, keep the temperature for half an hour, and close the loop. Cool to 60 ℃, filter and wash to obtain 1,8-naphthalene imide. |
