  • Oxidation of C1-9-alkanes
    Patent number: 10479748
    Abstract: A method for the oxidation of C1-9-alkanes including providing a mixture of a C1-9-alkane in a liquid phase, a boron containing reagent, a free radical initiator, and a drying means, and performing an oxidation reaction at a temperature from 130° C. to 180° C. in the presence of oxygen. The drying means may be a drying agent such as a molecular sieve, or a membrane. Also a composition for oxidation of C1-9-alkanes to sec-C1-9-alcohols.
