Cellulose-II single crystals from dilute copper-(II) ethylenediamine solution

This paper presents a new method for the preparation of cellulose-II single crystals by slow diffusion of hydrogen chloride into dilute copper-(II) ethylenediamine solution. The electron diffraction diagrams of the obtained crystals distinctly show the single crystal characteristic of the analyzed crystals. The magnitude of observable diffraction maxima is reported for the first time. The evaluation of the diffraction maxima determined by densitometric methods conforms well with the results published in literature.
