METHOD OF OXIDATING VEGETABLE OIL Russian patent published in 2017 - IPC C09F7/02 C09F7/12 C09F9/00 

FIELD: chemistry.

SUBSTANCE: method is described for oxidating vegetable oil in an oxidation column, consisting in the fact that to begin the oxidation process the column is filled with oil preheated to the temperature of 115-120°C, and air bubbling starts, initiating the oxidation process, in which, after the oxidation process in the column begins and the oil temperature inside the column rises to 145-150°C, oil is supplied to the bottom of the column from the additional tank, into which, before feeding it to the column, a certain amount of desiccant catalyst initiating the oil oxidation is added, oil heated by the reaction heat is oxidized, and a part of the oxidized oil is withdrawn from the top of the column and returned into the tank, circulating until the viscosity of the oxidized oil reaches the set value.

EFFECT: energy saving, the possibility of oxidizing a large amount of oil in an oxidizing column of small dimensions by circulating oil through an oxidation column.
