Chemsrc provides CAS#:5443-16-3 MSDS, density, melting point, boiling point, structure, etc. Its name is Anthracene-maleic anhydride diels-alder adduct
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. They have the same chemical formula, but the structure of the molecule differs from each other. However, both these compounds contain three benzene rings per molecule. CONTENTS.
99 °C Jean-Claude Bradley Open Melting Point Dataset 28423, 28424, 28425 fused benzene rings which takes its name from the two terms 'phenyl' and 'anthracene.' 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. (For the Diels-Alder reaction between anthracene-9-methanol and N-methylmaleimide) 1. If the melting point of your product is below 232-235°C, what will be the possible reasons? What could the impurities be?

The theoretical value of product is from 130 to 132 degrees Celsius. The result shows the product was very close to pure product since the experimental melting point is in the theoretical melting point range.
The major differences between anthracene and phenanthrene lie in the melting point and the properties directly related to solubility (Table 13.2). Phenanthrene is purified as brown to white monoclinic crystals, and also has the characteristic faint aromatic smell. Like anthracene, phenanthrene is used in the production of dyes. 5443-16-3.
