摘要: Process for oxidating paraffinic compounds in order to yield the corresponding alcoholic and/or ketonic compounds, which process consists of reacting said paraffins with an aqueous solution of hydrogen peroxide, possibly dissolved in a solvent, by operating at a temperature comprised within the range of from 0.degree. C. to 100.degree. C., in the presence of a titanium-silicalite of formulapHMO.sub.2.qTiO.sub.2.SiO.sub.2whereinM is a metal selected from among aluminum, gallium and iron,p is comprised within the range of from 0 to 0.05 andq is comprised within the range of from 0.0001 to 0.04, and the H.sup.+ of HMO.sub.2 can be least partially replaceable or replaced by cations.
