Definitions
- the present invention concerns a mixed oxide pilareado that maintains a separation between the sheets, appearing individual structural layers, which have channels and microporous cavities.
- Laminar materials such as clays, phosphates, hydroxycarbonates, silicic acids (kanemite, magadiite, keniaite, etc.), transition metal sulphides, graphite, laminar hydroxides and others, are susceptible to being swollen in the presence of water and / or cations appropriate interlaminar.
- the individual sheets of these materials are held together by weak forces of hydrogen bond type and / or electrostatic interactions. These bonds are easily broken when the intercalation force or the solvation energy of the cations is greater than the interlaminar attraction forces.
- the interest of the swollen materials is to make the interlaminar space accessible to the reactive molecules, and consequently, the internal surface, considerably increasing the active surface accessible to the reagent.
- the swollen sheet compound collapses, recovering the original interlaminar distance.
- the present invention includes the method of preparing the sheet solid and its subsequent treatment until it achieves a microporous pilared material of high accessibility and acidic characteristics that can be used as a catalyst. Description of the invention
- a pilareado material is prepared, which we have called ITQ-36, with microporous structure and high external surface, capable of supporting Br ⁇ nsted and Lewis acid centers, and which is characterized by its X-ray diffractogram and its adsorption properties and catalytic

- the synthesis takes place at temperatures between 100 and 200 ° C, with permanent agitation of the gel and a duration between 1 and 30 days and, preferably, between 2 and 12 days. After this time the reaction product, a white solid with a pH between 9 and 10 is washed with distilled water, filtered and dried.
- this material is used to prepare a suspension of the same in a solution that we will call "swelling", formed by a long hydrocarbon organic compound that has a proton acceptor group, such as a quaternary alkylammonium, an amine , or an alcohol with a number greater than three of chain carbons, to which a controlled amount of a compound capable of supplying OH "is added to the reaction medium, such as a quaternary alkylamine hydroxide, until a higher pH is reached to 10.
- the organic compound used can be any amine or quaternary alkylamine compound, preferably cetyltrimethylamine hydroxide (CTMA + OH " ).
- the swelling solution is prepared, it is mixed with the material described previously in a weight ratio of swelling solution to solid between 4 and 200.
- the resulting suspension is maintained at reflux and permanent stirring between 20 and 200 ° C, and preferably between 40 and 120 ° C, for a time not less than 1 hour until the swollen material is achieved.
- the product obtained is thoroughly washed with distilled water and dried at temperatures below 300 ° C and preferably below 150 ° C. Once washed and dried, the swollen material presents a characteristic X-ray diffraction diagram presented in Figure 1, and whose basic spacing and relative intensities are summarized in Table-1.

- This suspension is maintained at constant reflux and stirring, at a temperature between 30 and 150 ° C, and preferably between 50 and 80 ° C, for a time not less than 1 hour and with permanent nitrogen flow until the pilareado material is achieved.
- the product obtained is washed and dried at temperatures below 300 ° C. Once dry, it is calcined at temperatures between 300 and 800 ° C and, preferably between 400 and 600 ° C, giving rise to the product called ITQ-36.

- Pilareantes agents include polymeric oxides of elements of the VAT group of the Periodic System, such as Silicon, Germanium or Tin or of the IVB group such as Titanium, Zirconium, etc., although pillars that include polymeric silica are usually chosen.
- pilareant oxides could include an element that provides catalytically active acid positions on the pillars, preferably Aluminum, Gallium, Rare Earths or mixtures thereof.
- the ITQ-36 presents, along with its laminar character and X-ray diffractogram, characteristic textural properties as a result of having a microporous part, and a high external surface as a result of the cavities formed by the intercalation of pillars between the sheets.
- Table 3 summarizes the values obtained by applying the BET equation to the nitrogen adsorption isotherm at the temperature of the liquid nitrogen.
