Interaction of organic acids with silicates in the course of joint mechanical activation

Interaction of organic acids with silicates in the course of joint mechanical activation IR spectroscopy, X-ray phase analysis, and high-resolution electron microscopy were used to examine the nature of the interaction of organic acids with silicates in their joint mechanical activation for the example of succinic acid. It was found that mechanocomposites with chemically bound components are formed in the course of activation of acid–layered silicate mixtures. It was shown that in the acid/nano-SiO2 composite, monomer molecules of the acid are bound to nano-SiO2 via molecules of adsorbed water, which form rather strong hydrogen bonds with the basic active centers of nano-SiO2 and hydroxy groups of the monomer molecules of the acid. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals

Abstract

IR spectroscopy, X-ray phase analysis, and high-resolution electron microscopy were used to examine the nature of the interaction of organic acids with silicates in their joint mechanical activation for the example of succinic acid. It was found that mechanocomposites with chemically bound components are formed in the course of activation of acid–layered silicate mixtures. It was shown that in the acid/nano-SiO2 composite, monomer molecules of the acid are bound to nano-SiO2 via molecules of adsorbed water, which form rather strong hydrogen bonds with the basic active centers of nano-SiO2 and hydroxy groups of the monomer molecules of the acid.
