Why naoh was used in the nylon lab? Sodium hydroxide (NaOH) was added to the hexamethylenediamine solution in order to react with the hydrochloric acid (HCl) produced when the hexamethylenediamene reacts with the adiptic acid. The NaOH maintains the Page 5 pH of the solution by reacting with the HCl to form NaCl and water.
What is the role of the base in the synthesis of nylon? The base is present to neutralize the acid byproduct so that it does not protonate the amine, thus effectively deactivating it.
