1.012 grams Anthracene 1 mole Anthracene was the diene and maleic anhydride was the dienophile. The percent yield of the crude product was 69.03%. Following recrystallization of the product using xylene and vacuum filtration, a percent yield of 37.42% for the recrystallized product was collected. Anthracene was the diene and maleic anhydride was the dienophile. The percent yield of the crude product was 69.03%. Following recrystallization of the product using xylene and vacuum filtration, a percent yield of 37.42% for the recrystallized product was collected.

Weigh out 0.80g of anthracene and 0.40g of maleic anhydride (both are solids). Add the two solids into the flask.

The pi-system in this case is referring to a carbon-carbon double bond within the ring. View full document. Results Calculations Limiting reactant (.651g Anthracene)x (1mol Anthracene/178.23g) X ( 1 mol of diels alder adduct/ 1 mol of Anthracene) x (276.29g/mol adduct) =1.009g diel alder adduct (.350g Maleic Anhydride) x (1mol Maleic Anhydride/ 98.06g)x 1 mol of diels alder adduct/ 1 mol of Maleic Anhydride) x ( 276.29g/mol adduct) = . The standard molar enthalpy of combustion of the (anthracene + maleic anhydride) adduct at p o = 0.1 MPa was determined to be Δ c H m o (C 18 H 12 O 3, cr, 298.15 K) = −(8380.0±5.9) kJ·mol −1.

maleic anhydride should produce 2.27g of 4-cyclohexene-cis-dicarboxylic anhydride and 2.54g of 4-cyclohexene-cis-1,2-dicarboxylic acid (Eqs.1 and 2). The mass of the dicarboxylic anhydride before drying was 1.90g. The mass of the dried dicarboxylic acid was 1.06g, resulting in a 41.7 % yield. 14.9mmol maleic anhydride x 2.27 g 1mol 152.1494g (The maleic anhydride is slightly water sensitive). Weigh out 0.80g of anthracene and 0.40g of maleic anhydride (both are solids).

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 .
