Abstract
The systems MoO3/CCl3COOH and MoO3/CCl3COCl are able to intercalate into graphite. In the first case, we can demonstrate that the carbonic acid decomposes under the influence of molybdenum trioxide. One product of this reaction is trichloroacetic acid chloride. With the solvent trichloroacetic acid chloride we have varied the reaction parameters temperature, time and concentration of molybdenum trioxide. The received intercalation compounds were investigated by X-ray diffraction. From the obtained OOL patterns we calculate the stages of the compounds (pure third, fourth and mixed higher stages). The enlarged interlayer spacing varies between 924.6 pm (stage 4) and 916.3 pm (stage 3). The Cl/Mo-ratio lies between 4.6 (stage 4) and 3.8 (stage 3). From selected samples we have made monochromatic Laue-photographs. All photographs show the pattern of two hexagonal lattices. The lattice constant a of the smaller lattice corresponds to the value in the free molybdenum tetrachloride. The larger lattice is commensurate with the graphite lattice [(√43×√43)R 7.6°].
