Abstract
- In this paper, the depolymerization of waste polyamide-6,6 by using sodium-1-heptane sulphonate as a catalyst was carried out by acid hydrolysis. This method provides the recycling of polyamide into its monomer derivative which is dibenzoyl derivative of hexamethylene diamine. Depolymerization was carried out at different time from 30 min to 180 min by using 0.03 g of sodium-1-heptane sulphonate at 80°C by taking various amount of catalyst. Reaction takes place around 120 min to get 78.23% yield of the product. The product was analyzed by its melting point (154°C) and FTIR spectra and it was found to be same as the pure one. Kinetics shows pseudo first order with reaction rate constant 6.68 ×10<superscript>-3</superscript> minute-1. [ABSTRACT FROM AUTHOR]
