Definitions
- the present invention relates to the use of supported heterogeneous catalysts containing rhenium for the production of allylic alcohol from glycerol, as well as a process for the production of allylic alcohol from glycerol, in the presence of such heterogeneous catalysts.
- Allyl alcohol is known as a valuable material in the chemical industry. It can be used as is, but also as a raw material to produce a variety of high tonnage chemicals such as acrolein, acrylic acid or acrylonitrile. It is also used as an allylating agent in modern organic chemistry (Sundararaju et al., Chem. Soc. Rev., 2012, 41, 4467-4483).
- allyl alcohol is obtained by selective hydrogenation of acrolein, itself most conventionally resulting from a process for the selective oxidation of propylene.
- Glycerol is one of the most important renewable platform molecules, as it is a co-product of the transesterification process for the production of biodiesel (around 100 kg of glycerol is produced per tonne of biodiesel).
- the recent expansion of the biodiesel market has resulted in an overabundance of glycerol, which makes it very attractive as a substrate for the synthesis of more valuable chemicals.
- Application EP3124462 also describes a process for the direct deoxydehydration of glycerol to allylic alcohol, using a heterogeneous catalyst based on rhenium oxide on an alumina support of formula ReOs / A Os, in the presence of at least an aliphatic alcohol.
- the present invention responds to this problem: the process according to the invention aims to produce allyl alcohol from glycerol, with a high yield and very good productivity.
- This process uses a heterogeneous catalyst based on rhenium on a cerium oxide support of formula Re0 x / Ce0 2 .
- a first object of the present invention is therefore the use of a catalyst based on rhenium supported on cerium oxide of formula ReO x / CeC> 2 (I), to catalyze the deoxyd dehydration of glycerol to allylic alcohol, said reaction being carried out under heterogeneous conditions and in the presence of at least one aliphatic alcohol.
- the catalysts of formula (I) above make it possible to carry out the deoxidization of glycerol to allyl alcohol on a practical scale with a yield of up to about 90%, that is to say much higher than with the catalysts. based on supported iron oxide of the prior art. In addition, such catalysts allow to carry out this reaction with a much better productivity than the catalysts of formula Re03 / Al 2 C> 3. Finally, the catalysts of formula (I) are reusable and easily recoverable from the reaction mixture.
- catalysts of formula (I) above those in which the amount of ReO x varies from 2% to 20% by weight relative to the total mass of catalyst of formula (I) are preferred, more particularly, those in in which the amount of ReO x varies from 3% to 15% by weight, and preferably from 4% to 12% by weight.
- the catalysts of formula (I) above can in particular be prepared by impregnation at incipient humidity of cerium oxide (Ce0 2 ) with an aqueous solution of perrhenic acid (HReC> 4). After impregnation, the resulting catalyst of formula (I) is preferably dried at a temperature ranging from about 100 ° C to 150 ° C for several hours and then calcined.
- Another object of the present invention is a process for the production of allyl alcohol from glycerol in the presence of a catalyst, said process comprising only a step of dehydration of the glycerol, said reaction being carried out under heterogeneous conditions, in presence of i) a catalyst based on rhenium oxide supported on cerium oxide of formula ReO x / Ce0 2 (I) and ii) at least one aliphatic alcohol.
- the process according to the invention comprises one step, i.e. it makes it possible to obtain allyl alcohol from glycerol in a single step.
- the process according to the invention makes it possible to produce allyl alcohol without using raw materials derived from fossil resources. It is simple to perform (only one step) and very selective. This results in allyl alcohol, with yields of up to about 90%.
- the catalyst of formula (I) is chosen from catalysts in which the amount of ReO x ranges from approximately 2 to 20% by weight relative to the total mass of catalyst. of formula (I), and more particularly, those in which the amount of ReO x varies from 3% to 15% by weight, and preferably from 4% to 12% by weight.
- the specific surface of the cerium oxide used to support ReO x ranges from approximately 100 m 2 / g to 300 m 2 / g and more preferably still from 150 m 2 / g at 250 m 2 / g (BET method).
- Aliphatic alcohol is used as a solvent. Aliphatic alcohol also acts as a sacrificial reducing agent during the conversion of glycerol to allylic alcohol.
- the aliphatic alcohol is a monohydric alcohol having 6 to 10 carbon atoms, preferably 6 to 8 carbon atoms.
- monohydric alcohols having 6 to 10 carbon atoms preferably 6 to 8 carbon atoms
- secondary alcohols are preferred.
- the aliphatic alcohol is 2-hexanol.
- the deoxydehydration reaction is preferably carried out at a temperature greater than or equal to approximately 140 ° C and more preferably at a temperature ranging from approximately 140 ° C to 150 ° C. A temperature of about 145 ° C. is even more particularly preferred according to the invention.
- the deoxydehydration reaction is carried out using glycerol with a purity of at least 80%, preferably at least 85%, preferably at least. at least 90%, preferably at least 95%, preferably at least 99%. More preferably, the deoxydehydration reaction is carried out using glycerol with a purity of at least 95%, preferably at least 99%.

This is illustrated in particular in Example 1. According to such a method, typically, the volume of impregnation solution (ie aqueous solution of perrhenic acid (HReC> 4)) used is equal to the pore volume of the support (CeC> 2).
