Abstract
New catalysts based on magnesium orthophosphate, process for preparing it and applications The catalysts correspond to the formula XmMgn(PO4)p where X is an alkali metal cation selected from sodium, lithium and potassium and m = 0 or 1, n = 1 or 3 and p = 1 or 2, under certain conditions. The process comprises (a), reacting magnesium chloride with sodium hydrogen phosphate at pH 9 and ambient temperature, (b) adding an alkali metal carbonate to the reaction medium from (a) heating to 60-80 degree C for some 5 hours and (c) calcining the solid obtained to produce compounds of formula XMgPO4 in which X = Na, Li, K. If step (b) in the process is eliminated Mg3(PO4)2 and H2O are obtained, in which Y = 22.8 or 5. These products are useful as catalysts in processes for the dehydrogenation and dehydration of alcohols, aldol condensation and hydrogen transfer.
