The object of research is the chemical synthesis of double is layer hydroxides. The aim of the work is to establish new knowledge about heterogeneous chemical processes occurring in the synthesis of hydroxide and oxide materials. Research methods are X-ray phase analysis, gravimetry, voltammetry, thermogravimetry, scanning electron microscopy, spectrometry. Recommendations for optimal conditions and improvement of the synthesis process of double-layer hydroxides intercalated with functional anions are developed due to experimental studies on the influence of physical and chemical factors on their phase composition and physico-chemical properties. The developed recommendations include: synthesis of ni-Al double-layer hydroxides intercalated with indigocarmine anions( active substances of hybrid supercapacitors); synthesis of Zn-Al double-layer hydroxides intercalated with tripolyphosphate anions ("smart" white Anticorrosive pigments); synthesis of Zn-Al double-layer hydroxides intercalated with tartrazine anions (cosmetic pigments for Gel nail polish). A method for the synthesis of double-layer hydroxides (Zn-Al-nitrate) under conditions of continuous crystallization during their chemical precipitation, as a basis for intercalation of functional anions, has been developed. The method is based on single-stage synthesis at a constant ph by simultaneously feeding two or three solutions. Area of application: C 20.59 Manufacture of chemical products, n. at. and. at. ; M 72.19 Research and experimental development in the field of other natural and technical sciences.
