| | Dibenzo-18-crown-6 Usage And Synthesis |
| Chemical Properties | white to slightly beige fluffy powder | | Uses | Crown ether/Dibenzo-18-crown-6 for synthesis. CAS 14187-32-7, molar mass 360.41 g/mol. | | Uses | Dibenzo-18-crown-6, is used as an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff. It is an important organic intermediate. | | Definition | ChEBI: Dibenzo-18-crown-6 is a crown ether that is 18-crown-6 ortho-fused to two benzene rings at positions 8-9 and 17-18. It has a role as a phase-transfer catalyst. It is a member of benzenes and a crown ether. | | Purification Methods | Crystallise it from *benzene, n-heptane or toluene and dry it under vacuum at room temperature for several days.
