- extruded granules is understood to mean grains obtained by extrusion.
- the granules are obtained by extraditing an extrudable mass containing the titanium zeohte and by cutting the extradate leaving the granular extruder.
- the extruded granules can have any shape. be full or hollow They can be of round or rectangular section or of another section with a higher external surface. The cylindrical shapes are preferred.
- the extruded granules of cylindrical shape advantageously have a diameter of at least 0.5 mm, preferably at least 1 mm
- the diameter is usually at most 5 mm, in particular at most 2 mm
- Cylindrical shapes usually have a length of at least 1 mm, in particular at least 2 mm
- the lengths d '' at most 8 mm are common, those at most 4 mm give good results
- Cylindrical shapes with a diameter of 0.5 to 5 mm, preferably 1 to 2 mm, and a length of 1 to 8 m m, preferably 2 to 4 mm are suitable
- the content of titanium zeohte in the catalyst according to the invention is generally at least 1% by weight, in particular at least 50% by weight
- the content of titanium zeolite is most often at most 99 % by weight, in particular at most 98% by weight
- the catalyst according to the invention generally contains from 1 to 99% by weight, preferably from 50 to 98% by weight, titanium zeolite, the remainder consisting of a matrix. This matrix preferably contains a siliceous material.
- the catalyst according to the invention can be obtained by a process comprising:
- step (b) a step of shaping the dough obtained in step (a) by extrusion, in order to obtain an extradate
- Step (c) a drying step, in order to remove at least part of the water, (d) a calcination step, in order to remove at least a part of the organic residues present, and comprising a granulation step carried out between step (b) of extrusion and step (c) of drying or after step (d) of calcination, in order to obtain extruded granules.
- Step (a) generally consists in mixing a titanium zeolite powder with water, at least one binder, at least one plasticizer and possibly other additives until a paste of such viscosity is obtained. that it can be used in an extruder.
- the mixing can be carried out in any mixer or kneader. All the constituents of the mixture can be mixed simultaneously.
- the mixing is advantageously carried out at room temperature.
- the particle size of the titanium zeolite powder used in step (a) can vary to a large extent. It is preferably characterized by an average diameter less than or equal to 10 ⁇ m, in particular less than or equal to 5 ⁇ m.
- the average diameter is generally at least 0.05 ⁇ m, in particular at least 0.1 ⁇ m. Diameters less than 0.05 ⁇ m are also suitable.
- the plasticizer which can be used in step (a) can be a polysaccharide such as a starch or a cellulose. Celluloses are fine. Mention may be made, as examples of cellulose, of methyl-, carboxymethyl- and hydroxyethylcellulose.
- the amount of plasticizer used in step (a) can vary to a large extent. Reduced amounts of at least 1% and less than 10% by weight relative to the weight of titanium zeolite used are recommended because they lead to better resistance to attrition compared to higher amounts.
- the binder that can be used in step (a) can be chosen from silicon derivatives such as siloxanes. We can cite as examples the ethers of methyl- or ethylsiloxane.
- Polymethylsiloxane-based silicone resins can also be used. Polymethyl / phenylsiloxane type silicone resins are also suitable. It can also be mixtures of different oligomers of the methylsiloxane type.
- the binder used in step (a) can be in the form of a powder. Alternatively, it may be in the form of an aqueous emulsion. It can also be used in liquid form. Silicone resins based on polymethylsiloxane in the form of a powder and mixtures of different oligomers of the methylsiloxane type in liquid form are preferred because they lead to catalysts of higher mechanical strength.
- the binder is transformed, in step (d) of calcination. in a material constituting the matrix present in the catalyst according to the invention.
- the amount of binder used in step (a) can vary to a large extent. It is usually at least 3% by weight, in particular at least 5% by weight, relative to the weight of titanium zeolite used. It is commonly less than 30% by weight, relative to the weight of titanium zeolite used. The amounts of 5 to 20% by weight relative to the weight of titanium zeolite used are particularly suitable because they lead to a better compromise between catalvtic activity and mechanical strength compared to the lower and higher amounts. Lubricants can also be added to the mixture of step (a).
- They may be paraffin-based compounds, polyvinylpyrrolidone, polyethyleneoxide and polyvinyl alcohol.
- Porogenic substances can also be added to the mixture of step (a). These substances are removed during step (d) of calcination and thus increase the porosity of the catalyst. Mention may be made, as examples of pore-forming substance, of melamine.
- the amount of pore-forming substance used is generally at least 5% by weight, in particular at least 6% by weight, relative to the weight of titanium zeolite used. It is usually at most 35% by weight, in particular at most 14% by weight, relative to the weight of titanium zeolite used.
- the amounts of 6 to 14% by weight relative to the weight of titanium zeolite used are particularly suitable because they lead to better resistance to attrition relative to the higher amounts.
- Extraction step (b) can be carried out in a piston extruder. As a variant, it can be produced in a screw extruder.
- the drying step (c) is advantageously carried out at low drying rates to ensure good cohesion of the catalyst. For example, pre-drying at low temperature (for example from room temperature to 90 ° C, possibly in combination with infrared or microwave irradiation) can first be carried out; then the temperature can be slowly increased to reach the final drying temperature. Alternatively, when the water can be removed quickly by adequate ventilation, the temperature can be increased at a higher speed. Temperatures of 100 to 400 ° C may be suitable when the drying time is long enough, for example 10 to 20 hours.
- the calcination step (d) is generally carried out at a temperature of at most 550 ° C. Temperatures above 550 ° C are not recommended as most titanium zeolites do not withstand such temperatures.
- the duration of the calcination step (d) must be long enough to be able to remove most of the organic residues from the binder and / or the plasticizer. Typical durations of 60 hrs.
- the calcination step (d) is preferably carried out under an oxidizing atmosphere, for example in air.
- the catalyst according to the invention can be used in the synthesis of oxiranes by reaction between an olefinic compound with a peroxide compound.
- the invention therefore also relates to the use of the catalyst described above in these syntheses.
- the invention also relates to a process for the manufacture of an oxirane by reaction between an olefinic compound and a peroxide compound in the presence of the catalyst described above.
- the oxirane is preferably 1,2-epoxy-3-chloropropane or 1,2-epoxypropane.
- the olefinic compound is preferably allyl chloride or propylene.
- the peroxide compound can be chosen from those containing active oxygen and capable of carrying out an epoxidation. Hydrogen peroxide and peroxide compounds which can produce hydrogen peroxide under the conditions of the epoxidation reaction are well suited.
- the peroxide compound is preferably hydrogen peroxide.
