A METHOD FOR PRDUCING OF CLAY-AMINO ACID COMPLEX USING INTERCALATION REACTION

摘要

The invention of the layered clay structure by using a reaction-amino acid A method for producing a composite, (a ) Sodium After adjusting the pH by adding a pH adjusting agent, including a 1N hydrochloric acid and 1N aqueous sodium hydroxide solution to an aqueous solution of the clay (clay), including montmorillonite, and the stirring was continued at room temperature for more than one day, swelling the clay aqueous phase; (B) valine, threonine, a clay swollen in an aqueous solution of amino acids, including glutamic acid and lysine solution and step (a) 1: 1 were mixed in a volume ratio of, the ion-exchange reaction between the cation and the amino acids present between the layers of clay by induction, of the layered clay structure to produce an amino acid complex phase; (C) step (a) of the layered structure produced in clay - and the amino acid complex was centrifuged, washed repeatedly to step using methyl ethyl ketone as a cleaning solvent; And (d) centrifuging and washing the clay of lamellar structure to a method comprising the step of drying the amino acid complex. According to the invention, the water-swellable clay in the interlayer of the light monmo reel Na ⁺ , which substituted ions intercalated into amino acids (intercalation) by a reaction between the layer and the layer of clay Na ⁺ of the layered clay structure configured layer in place of the presence of amino acid-amino acid complexes can be prepared. Use methyl ethyl ketone as a cleaning solvent, the layer structure of the centrifuged clay-amino acid complex by the repeated washing, prevents the amino acid is eluted intercalated layered structure is collapsed, and the interlayer distance can be enlarged so that more there.
