A reducing-dehydrating catalyst for synthesizing vinylaromatic compounds from aromatic carbonylic compounds, consisting mainly of 5 - 50 per cent by weight of magnesium sulfate and 50 - 95 per cent by weight of zinc oxide. The catalyst can also contain magnesium oxide, in which case the composition of the catalyst is as follows: MgSO4 5 - 20 per cent by weight, ZnO 45 - 88 per cent by weight and MgO 2 - 45 per cent by weight. |
