In this experiment, a Diels-Alder reaction will be performed to generate 4-cyclohexene- 1,2-dicarboxylic anhydride. The reaction occurs when 1,3-butadiene is combined with maleic anhydride and heated as shown below. Once the product has been isolated, the IR spectrum, melting point, and experimental yield can be determined. 5.- I111NI O Due to the inherent difficulties with the handling of gaseous 1,3-butadiene, it will be generated in situ from 3-sulfolene which is a stable solid at room temperature. Heating the 3- sulfolene results in a rearrangement, producing the gaseous 1,3-butadiene that reacts with the maleic anhydride as it is produced to form the above product.
Experimental Procedure Weigh out 1.0 gram of powdered maleic anhydride and 1.8 g of 3-sulfolene. Add it to a clean and dry 50 mL round-bottom flask. Add a boiling chip followed by 2 mL of xylene. Swirl the mixture in the flask to dissolve the maleic anhydride and 3-sulfolene. Clamp the flask securely in a sand bath set on top of a hotplate. Insert a thermometer in to the sand bath and use a clamp to secure it. Attach an air-cooled reflux condenser to the round-bottom flask and then attach a calcium chloride drying tube. Slowly bring the mixture to a reflux. Reflux for a total of 30 minutes. When the reflux period is over, carefully adjust the clamp to raise the reaction flask out When of the sand bath. Allow it to cool to room temperature. Remove the condenser and drying tube and add a minimal amount of hot xylenes to wash the sides of the reaction flask. Transfer the contents of the flask to a 100 mL Erlenmeyer flask using a Pasteur pipette. Repeat this wash again with hot xylene to ensure quantitative transfer. Allow the contents of the Erlenmeyer flask to cool to room temperature. Add petroleum ether to the Erlenmeyer flask with swirling until a cloudy precipitate forms. Place the Erlenmeyer flask onto the warm sand bath and swirl until the contents completely dissolve. At this point remove the flask from the sand bath and allow it to cool to room temperature. Crystals of product should begin to form as the solution cools. Once the solution is at room temperature place the flask in an ice water bath to cool even further.

Solution :

Number of moles of maleic anhydride = Mass/Molar mass

= 1.0 g / 98.06 g mol-1 = 0.0102 mol

Number of moles of 3-sulfolene = mass /molar mass

= 1.8 g / 118.16 g mol-1 = 0.0152 mol

Since, number of moles of maleic anhydride is less than 3-sulfolene. Hence, maleic anhydride will be the limiting reagent.
