Optimization of reductive debenzylation of hexabenzylhexaazaisowurtzitane (the key step for synthesis of HNIW) using response surface methodology

Reductive debenzylation of hexabenzylhexaazaisowurtzitane (HBIW) was carried out using palladium hydroxide deposited on activated carbon catalyst. The catalyst has been characterized using a nitrogen adsorption/desorption isotherm, a hydrogen isotherm, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The synthesized catalyst showed pore sizes larger than 20 A, which are attributed to mesopore structures. A multivariate optimization approach was developed by means of central composite design (CCD) for optimizing reaction conditions. The influence of four variables, including the catalyst to HBIW (1) relative percent, reaction temperature, hydrogen pressure, and acetic anhydride (Ac2O), on the reaction yield was investigated. The results showed that the optimum parameters for reductive debenzylation were 20% (w/w) for catalyst to HBIW (1) percent, 48.5 °C for reaction temperature, 4.25 bar for hydrogen pressure, and 10.9 for Ac2O/HBIW mole ratio. Under these conditions, the reaction yield increased to 73%.
