Abstract: The purpose of the lab was to react the resultant acid from the previous week and a nucleophile to obtain an acid chloride, and from there to do another reaction in order to form nylon. It was hypothesized that if the adipic acid was reacted with thionyl chloride that adipoyl chloride would be formed. It was also hypothesized that when the adipoyl chloride was reacted with hexanediamine that nylon would be produced. A reflux condenser was used for the first part of the lab to help keep the vapors from getting into the air. The laboratory hood was used for the addition of certain chemicals in both part of the lab do to their chemical properties. The experiment was successful. Nylon was indeed the end product.
Introduction:…show more content… The adipic acid was reacted with thionyl chloride as a nucleophilic substitution reaction to form adipoyl chloride (Mayo, et al, 2011). The adipoyl chloride was mixed with 1,6-hexanediamine. Nylon was the product of the condensation polymerization of the adipoyl chloride. The thionyl chloride was the preferred reagent in part one because it was a fairly cheap product and as it reacted with the acid it produced a pure substance (Mayo, et al, 2011). This was possible because as it reacted the by-products became gases – no by-products to sort out equals a pure product (Mayo, et al,
