Abstract

In contrast with the conventional physical methods, the sub- and supercritical hydrolysis is not only a more environmentally friendly method to recycle the monomer casting nylon (MC nylon) wastes, but also a more feasible way to produce the corresponding monomer. In subcritical water, MC nylon was decomposed completely into water-soluble oligomers. The catalyzed hydrolysis of waste MC nylon using a series of H-form zeolites in subcritical water is presented in this work. Among them, H-Beta especially showed an excellent catalytic property and remarkably high yield of the monomer -caprolactam.
