摘要:A method for incorporating diverse Varieties of intercalants or templates directly during hydrothermal synthesis of clays such as hectorite or montmorillonite-type layer-silicate clays. For a hectorite layer-silicate clay, refluxing a gel of silica sol, magnesium hydroxide sol and lithium fluoride for two days in the presence of an organic or organometallic intercalant or template results in crystalline products containing either (a) organic dye molecules such as ethyl violet and methyl green, (b) dye molecules such as alcian blue that are based on a Cu(II)-phthalocyannine complex, or (c) transition metal complexes such as Ru(II)phenanthroline and Co(III)sepulchrate or (d) water-soluble porphyrins and metalloporphyrins. Montmorillonite-type clays are made by the method taught by U.S. Pat. No. 3,887,454 issued to Hickson, Jun. 13, 1975; however, a variety of intercalants or templates may be introduced. The intercalants or templates should have (i) water-solubility, (ii) positive charge, and (iii) thermal stability under moderately basic (pH 9-10) aqueous reflux conditions or hydrothermal pressurized conditions for the montmorillonite-type clays.

摘要:The invention relates to a method for synthesizing a liquid melamine resin, wherein: a) melamine, at least one aldehyde and at least one alcohol are fed to at least one first reactor operated continuously, in particular at least one agitated tank operated continuously and are reacted together, b) the reaction product that is obtained is fed to a solid-liquid phase separation device, c) a solids-rich phase that has been produced in the solid-liquid phase separation is fed back to at least one first reactor, and d) a phase devoid of solids that has been produced in the solid-liquid phase separation is subjected to additional processing steps. The invention thus provides an efficient continuous direct synthesis method for a liquid melamine resin.
