Process for the selective oxidation of hydrocarbons and their derivatives

摘要

A process for the oxidation of hydrocarbons and their derivatives having the general formula RX, wherein R is from n-alkyl, iso-alkyl, benzyl, cyclohexyl, mono, di or tricyclic aryl, or alkenic groups and X is selected from H, OH or Cl to compounds having formula R1XY wherein R1=(R-H), X has the meaning defined as above and Y=OH; which comprises of reacting the appropriate hydrocarbon or it's derivative of the formula RX where R and X have the meaning given above, with a solution of aqueous hydrogen peroxide at a temperature in the range of 10 DEG -100 DEG C. in the presence of an amorphous titanium-silicate catalyst having molar chemical composition in terms of the anhydrous oxides of TiO2: (5-400) SiO2, having an average micropore radius between 10 and 40 ANGSTROM , an absorption band around 220 nm in the ultraviolet region, a band around 960 cm-1 in the infrared region, interatomic vectors around 1.6-1.7, 2.7-2.8, 4.1-4.2 and 5.0-5.2 ANGSTROM in the radial electron density distribution and absence of any line in the x-ray diffraction pattern; and isolating the resultant products of the oxidation reaction by conventional methods.
