説明

As a result of many trials, authors found that the X-ray diffraction patterns of above mentioned matters could be successfully measured by grinding with about same amount of liquid paraffin. Suitability of this method was proved by Na2SO4·10H2O and authors proposed a new X-ray diffraction pattern of K4P2O7, which has not been ascertained yet.<BR>The X-ray diffraction patterns of 95% ethanol-insoluble matters of liquid detergents which contain K4P2O7, are usually in discord with the spectrum of K4P1O7. The observation of this fact indicates the formation of the solid solution between K4P2O7 and Na4P2O7, which is formed by the partial substitution of K+ of K4P2O7 for Na+ of anionic surfactants. In addition, it was found that the approximate value of K/Na ratio can be estimated from the shift of diffraction angle (2θ=3033°).
