UV–vis spectra were obtained with a single-beam spectrophotometer at room temperature. PL spectra were recorded on HORIBA JY FluoroLog-3 equipped with quartz cuvettes of 1 cm path length at room temperature.

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.

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. The melting point of anthracene ranges between 208 and 218 °C, mainly depending on the grade of purity.

What Could The Impurities Be? Explain Why Those Impurities Could Still Be Present In Your Final Product. Discussion:After the experiment finished, the melting point of trans-9-(2-phenylethenyl) anthracene test to be 131 degrees Celsius. 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. Reference substance name: Anthracene-9-carbaldehyde EC Number: 211-383-0 EC Name: Anthracene-9-carbaldehyde CAS Number: 642-31-9 Molecular formula: C15H10O Anthracene-maleic anhydride diels-alder adduct (5443-16-3), Wholesale Various High Quality Anthracene-maleic anhydride diels-alder adduct (5443-16-3) Products from Global Sodium Tripolyphosphate Suppliers and Anthracene-maleic anhydride diels-alder adduct (5443 … Answer to 0.150 g of anthracene (C14H10- melting point= 216 degrees C) is added to 3.00 g of naphthalene.

Benz[a]anthracene undergoes meso-anthracenic methylation by S-adenosyl-L-methionine (SAM), in the presence of a rat liver cytosol preparation, in vitro, to form 7,12-dimethylbenz[a]anthracene and presumably the moderately active carcinogens 7-methylbenz[a]anthracene and 12-methylbenz[a]anthracene.

Similarly, although the substituent group is the same for 2-and 9-anthracenecarboxylic acid, the melting point of 2-anthracenecarboyxlic acid is significantly higher, over 60 K higher, than its 9-carbon position counterpart. Chemsrc provides Benz(a)anthracene(CAS#:56-55-3) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Articles of Benz(a)anthracene are included as well.
