preparation example Construction

[0049] In step (1), "providing a mesoporous molecular sieve material with a three-dimensional cubic pore structure" can be directly weighed or selected a product of a mesoporous molecular sieve material with a three-dimensional cubic pore structure, or can be prepared with a three-dimensional cubic pore structure. Mesoporous molecular sieve materials. The preparation method of the mesoporous molecular sieve material with a three-dimensional cubic channel structure can be implemented according to a conventional method, for example, the preparation method can include: preparing a filter cake of a mesoporous molecular sieve material with a three-dimensional cubic channel structure according to the above method, and then The obtained filter cake is dried, and the templating agent in the product obtained after drying is removed. The conditions for removing the template agent may include: a temperature of 300-600° C. and a time of 10-80 hours.

Embodiment 1

[0091] This example is used to illustrate the spherical illite mesoporous composite material and supported catalyst of the present invention and their preparation methods.

[0092] (1) Preparation of spherical illite mesoporous composites

[0093] Dissolve 6g (0.001mol) of triblock copolymer surfactant P123 in 10ml of hydrochloric acid aqueous solution with a pH value of 4 and 220ml of deionized aqueous solution, stir for 4h until P123 dissolves to form a transparent solution, and then add it to the transparent solution Add 6g (0.08mol) of n-butanol and stir for 1h, then place it in a water bath at 40°C, slowly add 12.9g (0.062mol) of tetraethyl orthosilicate into the solution, and keep the temperature at about 40°C. Stir for 24 hours at a pH value of 4.5, then hydrothermally treat at 100°C for 24 hours, then filter and wash with deionized water for 4 times, and then suction filter to obtain filter cake X1 of mesoporous molecular sieve material with three-dimensional cubic por...

Embodiment 2

[0111] This example is used to illustrate the spherical illite mesoporous composite material and supported catalyst of the present invention and their preparation methods.

[0112] The spherical illite mesoporous composite material and the supported catalyst were prepared according to the method of Example 1. The difference was that there was no spray-drying step in the process of preparing the supported catalyst, but only the benzenesulfonic acid was loaded on the spherical illite by the method of impregnation. On the illite mesoporous composite material, the supported catalyst Cat-2 was prepared.

Abstract

The invention relates to a spherical illite mesoporous composite material, a preparation method of the spherical illite mesoporous composite material, a spherical illite mesoporous composite material prepared with the method, a supported catalyst comprising the spherical illite mesoporous composite material, a preparation method of the supported catalyst, a supported catalyst prepared with the method, an application of the supported catalyst in a ketalation reaction, and a method for preparing cyclohexanone glycerol ketal with the supported catalyst. The spherical illite mesoporous composite material comprises illite, a mesoporous molecular sieve material with a three-dimensional cubic pore structure, and a mesoporous molecular sieve material with a hexagonal pore structure. When the supported catalyst prepared with the spherical illite mesoporous composite material as a carrier is applied in the ketalation reaction, the conversion rate of reaction raw materials can be substantially improved.

Description

technical field [0001] The invention relates to a spherical illite mesoporous composite material, a preparation method of the spherical illite mesoporous composite material, a spherical illite mesoporous composite material prepared by the method, and a loaded type containing the spherical illite mesoporous composite material Catalyst, a method for preparing a supported catalyst, the supported catalyst prepared by the method, the application of the supported catalyst in ketal reaction, and a method for preparing cyclohexanone glycerol ketal using the supported catalyst. Background technique [0002] Cyclohexanone glycerol ketal is a fragrance with delicate fragrance and floral and woody fragrance.
