The present invention relates to the use of rhenium-containing supported heterogeneous catalysts 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 heterogeneous catalysts.

Use of rhenium-containing supported heterogenous catalysts for the direct deoxy-dehydrated of glycerol to allyl alcohol

The present invention relates to the use of haloapatites as catalysts of the dehydration reaction of &#x3b1;-hydroxylated carboxylic acids or acid esters, in particular of lactic acid or of methyl lactate, and also to a process for producing unsaturated carboxylic acids or acid esters, in particular acrylic acid or methyl acrylate, in the gas phase in a stainless steel reactor, in the presence of such a catalyst.

Production of unsaturated carboxylic acids or acid esters with a haloapatite-based catalyst

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.

Use of molybdenum and vanadium mixed oxides as catalysts for the oxidation of unsaturated alcohols into unsaturated carboxylic acids

A compound of the formula SbFeO(I) in which x varies from 0.4 to 1 inclusive and y varies from 1.6 to 4 inclusive, may be used as a catalyst for catalyzing the ammoxidation reaction of an alcohol of following formula (II) CH&#x2550;C(R)&#x2014;CH&#x2014;OH (II) in which Rrepresents a hydrogen atom or a methyl radical, to give nitrile of following formula (III) CH&#x2550;C(R)&#x2014;C&#x2261;N (III) in which Rhas the same meaning as in above formula (II), the said reaction being carried out in the gas phase, the said gas phase comprising at least oxygen and ammonia. The present invention also relates to the process for the ammoxidation of an alcohol of formula (II) employing a compound of formula (I) as catalyst.

Process for the production of nitriles using a catalyst based on antimony and iron

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&#xb0; C. and 200&#xb0; C., in presence of an oxidant. The reaction medium may also comprise a solvent.

Oxidation of alcohol compounds via mesostructured VPO catalysts

The invention relates to a method for preparing acrolein from glycerol or glycerin, according to which dehydration of glycerol or glycerin is carried out in the presence of a catalyst which consists in at least one silica modified with zirconium dioxide, titanium dioxide or tungsten trioxide or any combination of these oxides, and a heteropolyacid. This method may be used for making 3-(methylthio)propionic aldehyde (MMP), 2-hydroxy-4-methylthiobutyronitrile (HMBTN), methionine or its analogs, from acrolein.
