OXIDATIVE METHODS OF REMOVING PHOSPHORUS FROM LIQUID HYDROCARBONS Russian patent published in 2019 - IPC C07C2/36 C07C7/148 C10G27/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of removing phosphorus compounds from liquid hydrocarbons. Method comprises steps of: (a) reacting a liquid hydrocarbon with an aqueous solution containing an oxidant selected from tert-butyl hydroperoxide to form a reaction mixture containing an aqueous component and a hydrocarbon component, where the liquid hydrocarbon contains at least alkene _C4-30 and trialkylphosphine _C≤30; (b) reacting an oxidant selected from tert-butyl hydroperoxide with trialkylphosphine _C≤30 with formation of corresponding phosphine oxide _C≤30; (c) removing the aqueous component from the hydrocarbon component while removing the trialkylphosphine oxide _C≤30 from liquid hydrocarbon.

EFFECT: disclosed invention makes it possible to efficiently remove phosphorus compounds from hydrocarbon liquids.
