METHOD OF OXIDIZED VEGETABLE OIL PREPARING Russian patent published in 2002 - IPC

Abstract RU 2190650 C1

FIELD: technology of oils preparing. SUBSTANCE: invention relates to a method of preparing oxidized vegetable oils used in paint and varnish, polygraphic, light industry, as a binding agent in building industry and other branches of industry. Method of preparing oxidized vegetable oils involves oxidation of semi-drying oils with air oxygen in the presence of pyropolymeric phthalocyanine or melamine-formaldehyde chelates of metals of transient valence Co, Mn, Ni, Fe applied on solid inert carriers at temperature 130-160 C, in blowing through with air 40 t-1 up to attainment viscosity value 960-1340 s. The proposed method is used for preparing light oxidized oils, in using regenerable heterogeneous catalysts of multiple using. EFFECT: improved method of preparing. 6 tbl, 22 ex
