| Abstract: | Terephthalic acid was obtained from p-dichlorobenzene, carbon monoxide and water when the reaction was carried out in the presence of nickel iodide supported on silica gel (Ni:SiO2 = 50:50) the catalyst which showed the best catalytic activity among those tested. The maximum conversion of p-dichlorobenzene to terephthalic acid at the optimum conditions was 14.9%. |
