Abstract: 1. A PROCESS FOR THE PREPARATION OF AN OXYCHLORINATION CATALYST COMPRISING THE STEPS OF FORMING A SILICA-MAGNESIA SUPPORT BY FORMING A SILICA HYDROGEL WITH A COMPOUND SELECTED FROM THE GROUP CONSISTING OF MAGNESIUM CHLORIDE, MAGNESIUM BROMIDE, MAGNESIUM PERCHLORATE AND MIXTURES THEREOF, CALCINING THE RESULTING HYDROGEL AT A TEMPERATURE OF 530 TO 700*C. TO FORM THE SUPPORT, WITH THE COMPOUND BEING EMPLOYED IN AN AMOUNT SUFFICIENT TO PROVIDE A HYDROGEL CONTAINING 10 TO 25% MAGNESIA BASED ON THE CALCINED PARTICLES, AND DEPOSITING ON THE SUPPORT A COPPER CHLORIDE CATALYST.
