Abstract:
The radical alkylation of cyclododecanone (CDD) with allyl acetate (AlAc) yielding 2‐[3‐(acetyloxy)propyl] cyclododecanone (CDDPA) in the presence of different inorganic radical initiators was investigated. The most useful initiator among other inorganic metal oxides was found to be CuO. The molar ratio of CDD and AlAc was varied between 10:1 and 3:1. CuO was characterized by using different analytical methods, such as N 2 adsorption, powder X‐ray diffraction, temperature‐programmed reduction, scanning electron microscopy, and X‐ray photoelectron spectroscopy. The reaction was performed in a batch system, by adding all the reactants at once, and in a semibatch procedure by dosing AlAc over the whole time of the experiment. Different parameters that affected the selectivity of CDDPA were studied, such as the ratio of CDD/AlAc, reaction time, surface of CuO initiator, and reaction temperature. The best result was obtained with 21 % conversion of CDD and 77 % selectivity to CDDPA at a final molar ratio of CDD/AlAc = 4:1 in the semibatch procedure.
