Problems solved by technology

In the case of more complex shaped bodies, however, the stated properties of the ionic liquids become more permissive, so that highly uniform coatings cannot be achieved with conventional methods

Embodiment 1

[0100] Embodiment 1: For using 10% by weight of ionic liquid 1-butyl-2,3-dimethylimidazole Triflate (BMMIM(OTf)) and 14 wt% homogeneous catalyst [Et 3 (Bz)N][Ru(CO) 3 Cl 3 ] Method for impregnation of KA-160 carrier spheres (5 to 6 mm) available from Süd-Chemie AG:

[0101] Weigh 7g of ionic liquid, 3.58g of ruthenium tricarbonyl dichloride and 6.38g of benzyltriethylammonium chloride into a 500ml round bottom flask. To this mixture was added 150 g of distilled water. A yellow solution formed (total weight 167 g). The solution was stirred for 5 minutes in an ultrasonic bath and heated to a temperature of 30°C.

[0102]70 g of support material KA-160 were fluidized in a fluidized bed apparatus with the help of air and impregnated with catalyst solution under different process conditions:

[0103] a) Delivery rate: 5ml / min

[0104] Process temperature: 80°C

[0105] Pressure: 1.0 bar

[0106] After applying all the catalyst solution by spray impregnation, the support w...

Embodiment 2

[0113] The same method as in Example 1 was performed except that the process temperature was lowered to 60°C. The distribution of homogeneous catalysts can be in image 3 see in image 3 A scanning electron microscope image in which a homogeneous catalyst is seen is shown. Figure 4 SEM images of distributions with ionic liquids are shown.

[0114] The shell thicknesses seen in the images for the ionic liquid and the homogeneous catalyst are 940 or 930 μm, respectively.

Embodiment 3

[0116] The same method as in Example 1 was performed except that the process temperature was lowered to 40°C. Figure 5 SEM images of the obtained products are shown, from Figure 5 It can be seen that the ionic liquid is extremely uniformly distributed on the support.

Abstract

A method for producing a composite material which contains a support material and an ionic liquid, as well as a composite material and its use as synthetic catalyst.

Description

technical field [0001] The present invention relates to a process for the production of a composite material comprising a support material and an ionic liquid, as well as the composite material and its use as a catalyst for synthesis. Background technique [0002] Recently, research has focused on materials consisting of a solid carrier component and a liquid component immobilized thereon. The loading of liquid components and substances that may be dissolved or suspended in them endows composites with excellent new properties. First, the immobilization of ionic liquids (ILs) on porous support materials is the focus of interest here. The resulting composites can be used in important industrial fields such as catalysis, gas purification, purification of fuel mixtures, separation of mixtures, rheology, etc. [0003] In the field of catalysis, first learn two topic-related concepts: [0004] In the case of the so-called SILP (Supported Ionic Liquid Phase, supported ionic liqu...
