FIELD: chemistry.
SUBSTANCE: method of producing organically modified layered double hydroxide involves preparation of a suspension containing a divalent metal ion source selected from oxides and hydroxides of a divalent metal, and a trivalent metal ion source selected from oxides and hydroxides of a trivalent metal; thermal or solvothermal treatment of the said suspension to obtain layered double hydroxide. An organic anion is added before or during or after formation of the layered double hydroxide. The organic anion has 8 or more carbon atoms, wherein a deoxycholic acid anion is not the only organic anion. The divalent and/or trivalent metal ion source is crushed and the suspending medium used is water. As a result, an organically modified layered double hydroxide is obtained, having distance between separate layers greater than 1.5 nm and containing an organic anion as a charge-compensating anion.
EFFECT: low amount of streams of harmful wastes formed during production of organically modified layered double hydroxides.
