摘要:
The present invention relates to the use of molybdenum and vanadium mixed oxides, optionally iron doped, as catalysts for the oxidation of unsaturated alcohols, in particular allyl alcohol, and also to a process for the production of unsaturated carboxylic acids, in particular acrylic acid, in the gas phase, in the presence of such a catalyst.
摘要:
The present invention concerns a process for the production of an aldehyde compound by an oxidation reaction of an alcohol compound in the presence of a mesostructured vanadium phosphorus mixed oxide catalyst, at a temperature comprised between 50° C. and 200° C., in presence of an oxidant. The reaction medium may also comprise a solvent.
摘要:
The invention relates to the use of haloapatites as a catalyst in the dehydration reaction of α-hydroxylated carboxylic acids or acid esters, in particular lactic acid or methyl lactate, as well as to a method for synthesizing unsaturated carboxylic acids or acid esters, in particular acrylic acid or methyl acrylate, in the gaseous phase in a stainless steel reactor in the presence of a catalyst of said type.
摘要:
The present invention relates to the use of an alumina-supported rhenium oxide catalyst for the deoxydehydration of glycerol to allyl alcohol, as well as to a process for the production of allyl alcohol from glycerol in the presence of such a heterogeneous catalyst.
