Abstract
Catalizadores de fórmula M(SO{sub,4}){sub,2}H{sub,3}O (M = catión de tierra rara) y su procedimiento de síntesis. Los compuestos objeto de la patente se han obtenido por síntesis hidrotermal por reacción de una mezcla de una sal de la tierra rara, propilamina y dimetilsulfóxido, como fuente de sulfato. Esta mezcla se calienta durante unos días a presión autógena. Después de este tiempo dejamos enfriar lentamente. Cuando alcanzamos temperatura ambiente abrimos el autoclave y filtramos los productos obtenidos, lavando con agua primero y luego con alcohol. Son sus aplicaciones en reacciones de hidrogenación de olefinas, y del grupo nitro, de compuestos nitroaromáticos y reacciones de oxidación de sulfuros.
