| titleOfInvention | SYNTHETIC, POROESIS, CRYSTALLINE SUBSTANCE, ITS SYNTHESIS AND USE |
| abstract | The present invention relates to a synthetic porous, crystalline substance. The invention also relates to a process for their preparation and their use in the catalytic conversion of organic compounds. Zeolitic substances, both natural and synthetic, exhibit catalytic properties for various types of hydrocarbon conversion. Certain zeolitic substances are ordered, porous, crystalline aluminosilicates which have a unique crystalline structure determined by X-ray diffraction, within which there are a large number of smaller cavities that can be interconnected by a number of even smaller channels or pores. Depending on the size of these cavities, certain molecules may or may not be absorbed, and this determines the catalytic properties of the zeolite. The present invention now relates to very specific synthetic porous, crystalline substances which are characterized by a very specific X-ray diffraction pattern characteristic of them. These zeolites have an equilibrium adsorption capacity of more than 10 * for water vapor, more than 4.5 * for cyclohexane vapor and more than 10 * for n-hexane vapor. The crystalline substance of this invention exhibits a composition which is where X is a trivalent element such as aluminum, boron, iron and / or gallium, but preferably aluminum, and Y is a tetravalent element such as silicon and / or germanium, but preferably Silicon and n is at least 10, most preferably from 10 to 150, preferably from 60 and even more preferably from 20 to 40. The crystalline substance of the invention can be used as a catalyst in intimate combination with hydrogenating components. It can be used to catalyze a wide variety of organic conversion processes including, for example, the hydration of C2 to C7 olefins such as propylene to alcohols and ethers under reaction conditions having a temperature of 50 to 300C, preferably 90 to 250C, a pressure of at least 5 kg / cm 2, preferably at least 20 kg / cm 2, and a water / olefin molar ratio of 0.1 to 30, preferably 0.2 bi {synthetic, porous, crystalline substance; zeolitic catalysts; specific X-ray diffraction pattern; Catalysis of organic transformation processes} |
