      Recently, scientists have attempted to transform traditional synthetic procedures into ones that are more environmentally favorable due to the desire to circumvent the damage being done to our environment. A technique was recently developed in which satellite dishes were repurposed as solar reflectors that are capable of providing a focused source of solar irradiation.� The ability to use the solar reflector as the sole heat source for synthetic reactions has been analyzed for the synthesis of the commercially important polyamide, nylon 6,6.� Commercially, Nylon 6,6 is synthesized using a multi-step procedure, in which nearly all of the steps require the addition of heat in order for the reaction to occur.� Furthermore, the synthesis also incorporates some chemicals/reagents that are not environmentally friendly or consist of elements that are considered endangered and supply are in serious danger.� The exchange of these reagents with more environmentally friendly, sustainable substitutes has been analyzed for the total synthesis of nylon 6,6.� The incorporation of a solar energy heat source and use of environmentally friendly chemicals provides a new synthetic route to nylon6,6 that can be taught in teaching labs as a �green synthesis� experiment or scaled to fit the needs of industrial synthesis.
