Xylene (6 mL), anthracene (0.5 g), and maleic anhydride (0.25 g) were added to a round bottom flask (25 mL). The solution turned a yellow color when the reactants were added together. The reflux was then started, and once it began to boil, it was boiled for 30 minutes.

Be sure to wear gloves and avoid contact with these compounds. In a dry round-bottom flask, combine 1.0g of anthracene and 0.5 g of maleic anhydride, add 12 ml of xylenes (a mixture of dimethylbenzenes), and reflux the reaction mixture for about I'm wondering why maleic anhydride adds to the middle cycle of anthracene, and not the outer two. I would have expected that a Diels–Alder with the outer ring would be better, because I expected a naphtalene part to be lower in energy than two benzene parts (more resonance stabilisation). 2019-11-21 Other names: Anthracene, 2,5-furandione adduct; Anthracene,maleic anhydride adduct; endo-9,10-(α,β-Succinic anhydride)anthracene; 9,10(3',4')-Furanoanthracene-12,14-dione; 9,10-Dihydroanthraceno-9,10-endo-α,β-succinic anhydride; 9,10-Ethanoanthracene-11,12-dicarboxylic anhydride … Jump to content. anthracene 9, 10-dihydroanthracene- 9,10-oçß-succinic anhydride* maleic anhydride potassium bromide xylene *product 1998 Chemical Education Resources 10-mL graduated cylinder hot plate 2 melting point capillary tubes microspatula 25-mL round-bottom flask support stand 13 x 100-mm test tube 2 utility clamps 3-mL product vial watch glass Diels Alder Rxn - SEE TITLE SEE TITLE .

Maleic anhydride is a classic substrate for Diels-Alder reactions. It was used for work in 1928, on the reaction between maleic anhydride and 1,3-butadiene, for which Otto Paul Hermann Diels and Kurt Alder were awarded the Nobel Prize in 1950. It is through this reaction that maleic anhydride converted to many pesticides and pharmaceuticals.

The influence of light on the Diels-Alder reaction between anthracene and maleic anhydride. You The standard molar enthalpy of combustion of the (anthracene + maleic anhydride) adduct at p° = 0.1 MPa was determined to be AcH~(CIsH1203, cr, 298.15 K) = reactants anthracene and maleic anhydride. The product spectrum yields peaks at 3073.89 cm -1 and 2969.78 cm -1 .

This reaction is a cycloaddition reaction in which the conjugated pi-systems of the two reactants join to form a new ring 1. The pi-system in this case is referring to a carbon-carbon double bond within the ring. View full document.

Reaction to form cis -Norbornene-5,6-endo -dicarboxylic anhydride (Pavia 417). The acylation of 5-aryl-substituted furfurylamines with maleic anhydride led to N-furfurylmaleic amides, which formed a dynamic equilibrium in solutions with adducts formed by intramolecular [4+2 18 Oct 2020 PREPARATION OF ANTHRACENE MALEIC ANHYDRIDE ADDUCT. 95 views95 views. • Oct 18, 2020.

a. First you need to find the molar mass:-look up on the periodic table what is called the atomic weight or molar mass (should be under the symbol).
