Definitions
- the present invention relates to a process for the production of diisobutyl ketone (DIBK) comprising bringing triacetone dialcohol (TDA) and a bifunctional catalyst capable of carrying out a dehydration and hydrogenation reaction.
- DIBK diisobutyl ketone
- TDA triacetone dialcohol
- DIBK Diisobutyl ketone
- DIBK is generally produced together with methyl isobutyl ketone (MIBK) in a condensation reaction of acetone.
- MIBK methyl isobutyl ketone
- DIBK diisobutyl ketone
- TDA triacetone dialcohol
- a bifunctional catalyst capable of carrying out a dehydration and hydrogenation reaction are brought into play.
- a bifunctional catalyst is a type of catalyst well known in the art and capable of catalyzing two types of reactions, also known as a dual function catalyst.
- the bifunctional catalyst of the invention allows dehydration in acidic or basic media and allows hydrogenation in particular in the presence of a metal supported on the catalyst. It is particularly preferred to carry out dehydration in an acid medium assisted by a high temperature.
- the bifunctional catalyst comprises as first component an acidic or basic solid compound.
- This compound may be an organic or inorganic solid of the alumina, zeolite, clay, ceramic, phosphate or resin type.
- acidic solid supports mention may be made in particular of sulfonic acid resins, carboxylic resins, phosphoric resins, mineral oxides such as sulphated zirconias, acidic clays such as montmorillonites and zeolites, such as H- ZSM5, and HY.
- As a basic solid support there may be mentioned compounds bearing on the surface hydroxide functions or amine functions, carbonates, metal oxides such as phosphate or lanthanum oxides, basic clays such as double-layered hydroxides (LDH).
- LDH double-layered hydroxides
- the catalytic system comprises as a second component an A, metal, alkali or alkaline earth metal compound.
- metal component mention may especially be made of those based on Cr, Co, Ni, Cu, Rh, Pd, Ir, Pt, Mo, W, Zn, P, As, Sb, Si, Ge, Sn, Al, Ga and Ti. , Zr, Hf and / or Au.
- alkaline or alkaline earth metal component mention may especially be made of those based on Li, Na, K, Rb, Cs, Be, Mg, Ca and / or Sr.
- Ni, Pd, Rh and Ir are preferred. can be used as such or in the form of hydroxide, oxide or salt.
- the metal is preferably in the reduced state for its activity during the hydrogenation.
- the bifunctional catalyst preferably comprises a metal compound based on Cr, Co, Ni, Cu, Rh, Pd, Ir, Pt, and / or Au.
- the platinum group metals in particular platinum, palladium, rhodium and ruthenium are particularly active catalysts, which act at low temperature and low H 2 . These catalysts are described in particular in application US2003 / 0139629, US Pat. No. 6,008,416 and the publication "Pd supported! on an Acidic resin ... Seki et al, Adv. Synth. Catal. 2008, 350, 691-705.
- the compound A, metallic, alkaline or alkaline-earth metal may be used in proportions of between 0.001% and 30% by weight, more preferably between 0.01% and 10% by weight, relative to the weight of the acidic solid compound. or basic.
- the catalytic system comprises an acidic or basic solid compound on which compound A described above is surface-supported.
- catalysts Amberlyst (R) CH28 may be mentioned. It is also possible that the catalyst system comprises an acidic or basic solid compound and a compound A supported on a reaction-inert solid.
- the catalyst can be placed on a fixed bed or be suspended with stirring in the reactor.
- the proportion of catalyst may vary between 0.01% and 60% by weight relative to the weight of the TDA, preferably between 0.1% and 20% by weight, more preferably between 1% and 10% by weight.
- the reaction medium comprises especially TDA, and optionally other compounds, such as one or more solvents for example.
- the reaction medium may optionally comprise one or more solvents, such as polar or apolar, protic or aprotic solvents, particularly polar protic solvents, polar aprotic solvents and apolar aprotic solvents. Alcohols, such as methanol, ethanol and isopropanone, are particularly preferred.
- the reaction medium preferably comprises 30 to 70% by weight of TDA and 30 to 70% by weight of DAA, more particularly 40 to 60% by weight of TDA and 40 to 60% by weight of DAA. In this case, DIBK is manufactured from TDA and MIBK is manufactured from DAA.
- the present invention thus also relates to a process for the production of DIBK and MIBK by bringing TDA and DAA into contact with the bifunctional catalyst of the present invention.
- the reaction medium may be derived from a DAA production unit, directly or indirectly; more specifically from the bottom of the distillation column of a DAA production unit, successively to the catalyzed condensation of acetone. It is perfectly possible to increase the TDA concentration of the medium from a DAA production unit, or to eliminate certain impurities, for example by distillation or crystallization.
- the reaction is carried out at a temperature of between 10 ° C. and 200 ° C., more preferably between 30 ° C. and 150 ° C.
- a temperature of between 10 ° C. and 200 ° C. more preferably between 30 ° C. and 150 ° C.
- the dehydration of TDA is increased by the synergistic effect of the acid catalysis of the bifunctional catalyst and the high temperatures.
- the reaction is carried out at a pressure of between 1 and 100 bar, more preferably between 3 and 25 bar, more preferably between 8 and 15 bar.
- a pressure can be obtained by adding feed to the reactor of pure hydrogen or a mixture of hydrogen and an inert gas, such as for example nitrogen or argon.
- the hydrogen partial pressure can be maintained by purging the gas head while controlling the hydrogen content.
- the process according to the invention can be carried out continuously or discontinuously, preferably in the liquid phase.
- the residence time of the reaction may in particular be from 5 to 300 minutes.
- the reaction can be carried out in a reactor of any type, in particular in a vertically mounted reaction tube. Several reactors implementing the method of the invention can be put in series.
- TDA triacetone dialcohol
- DIBK diisobutyl ketone
- the selectivity of a chemical reaction specifies the amount of desired product formed relative to the number of moles consumed of the limiting reagent. It indicates if several reactions occur in parallel, leading to unwanted by-products, or if the reaction sought is the only one to consume reagent. An excellent selectivity in DIBK is thus observed in the context of the process of the present invention.
