SYNT 717: The Diels-Alder Reaction of Anthracene with Maleic Anhydride. 103. When anthracene's center ring reacts as a diene, the product has two.

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 acid anhydride in relatively pure form. The remaining solid in the vial is likely to be yellow-green to dark green in color and is also mostly 9,10-dihydroanthracene-9,10-α,β-succinic acid anhydride. Small amounts of oxidized anthracene give it its color.

It is through this reaction that maleic anhydride converted to many pesticides and pharmaceuticals. Anthracene-maleic anhydride diels-alder adduct. Modify Date: 2021-03-19 17:52:33. Anthracene-maleic anhydride diels-alder adduct structure. Common Name. Anthracene-maleic anhydride diels-alder adduct.

Safety and Waste Disposal: Xylene is flammable, so keep it away from flames and hot plates. Experimental Procedure: Place 1.0 g of anthracene and 0.5 g of maleic anhydride in a 100-mL round-bottom flask. Add 15 O O O a .

1-octylmaleimide or maleic anhydride as a dienophile, assisted by their crystal structures could serve as a reference for such an endeavor. An octylmaleimide Diels–Alder adducts of anthracene (1) and a 9-substituted derivative (2) were obtained by reacting the corre-sponding anthracene derivative with 1-octylmaleimide as de-scribed in Scheme 1.

Second, the xylene mixture does not freeze when it is cooled in is between anthracene (the diene) and maleic anhydride (the dienophile):. This particular example is a widely used reaction in organic teaching labs, but the PROCEDURE. Transfer 4 g of anthracene, 2.2 g maleic anhydride and 50 ml of dry xylene in a 250 ml round bottom flask fitted with a reflux condenser.

In the present experimental work, the energy of combustion of the crystalline Diels-Alder adduct of anthracene and maleic anhydride: C 18 H 12 O 3, was measured with a model 1241 Parr automatic calorimeter and a Parr model 1710 calorimeter controller.The standard molar enthalpy of combustion of the (anthracene + maleic anhydride) adduct at p o = 0.1 MPa was â ¦ In this lab, the 4 electrons
