The reaction for this experiment is between anthracene and maleic anhydride and is a Diels-Alder reaction. 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. The reaction involves a carbon group called a diene and an alkene called a dienophile. When the reaction occurs, conjugate addition of the diene and the dienophile produces a sixmembered cyclohexene ring Abstract In this lab we synthesize Nylon 6,10 from hexamethylene diamine and sebacoyl chloride and was able to determine the length of the Nylon formed.

Nylons are semi-crystalline polymers. The amide group -(-CO-NH-)- provides hydrogen bonding between polyamide chains, giving nylon high strength at elevated temperatures, toughness at low temperatures, combined with its other properties, such as stiffness, wear and abrasion resistance, low friction coefficient and good chemical resistance. The amine molecule with its –NH2 group at each end, is able to react with the acid chloride that has a –COCl group at each end. The diamine and the diacid chloride bond together, endon-end, to form very long chains. Observations 1. In mixing out reaction mixture of SC and Diamine solution, We observe two layers of solution. This an immiscible mixture with the organic on top and the aqueous at the bottom in which polymerization occurs at the interface of the two layers 2. Using the glass rod, were able retrieve a string like substance from the interface of the two layers. This is our resulting nylon formed from the reaction 3. Our Nylon measures out to be roughly 120 cm long over a meter long. This suggests that we had ample experimental condition Results In completing the reaction, we can calculate the theoretical yield of our experiment. Theoretical Yield 1 ml of Sebacoyl Chloride (SC) x 1.121 g/ml =1.121 g of SC 1.121 g of SC x 1 mol / 239.41g of SC = 0.00469 mols 0.00469 mols x 331.34 g/mol of Nylon 6,10 = 1.55 g of Nylon 6,10 We weren’t given an actual yield of our polymer so we can’t derive a percent yield. Though we can assume that yield would not have been 100%. The reason why it could be a relatively high yield is simply that all the reactant did not participate in the reaction, we have some unrecovered product left in the beaker. We were able to measure out the nylon to be over a meter long as we used roughly 30 mL of the reagent. This suggest that most of our reagents were able to participate in the reaction as produced a very long string Conclusion In this brief experiment, we were able to produce roughly around 120 cm Nylon 6,10 product from an acid chloride and amine solution. This lab proved successful for not only synthesizing and determining the length of product, but also the mechanism involved in synthesizing it....
