The melting point of the crude product was 261 - 264°C. The melting point of the recrystallized product was 261 - 263°C. Comparing these values with the literature melting point of 262 - 264°C shows that the product was indeed 9, 10-dihydroanthracene-9, 10-α, β-succinic anhydride and that recrystallization yielded a purer product.

Symbol which looks like a small house Solid circle with an upward pointer in it. Jump to content 2012-09-04 · Why is anthracene more stable than phenanthrene? Although they have the same molecular weights, the melting point of anthracene is nearly twice that of phenanthrene. Explain. 2019-08-15 · The key difference between anthracene and phenanthrene is that anthracene is less stable compared to phenanthrene. Anthracene and phenanthrene are structural isomers.
