Abstract


Sixteen hydrogen maleate ester (HHM) is a new type of soft X-ray spectroscopy crystal lattice spacing 2d equal 58.58A, and OHM ( octadecyl hydrogen maleate ) belong to the same series analyzer crystal , carbon chains shortened decrease spacing OHM better than expected given the growth and crystal habit . In this paper, benzene as solvent solution cooling method cultivate a 60mm × 40mm × 3mm large size HHM crystal ; Also discussed HHM in the growth behavior of carbon tetrachloride solution , the solution cooling method cultivate a 20mm × 20mm × 1mm longer- large size single crystal with a stereomicroscope dynamic cycle determined observation method different supersaturation in the major crystal faces exposed normal growth rate , the greater the degree of supersaturation within the investigated surface diffusion of the BCF screw dislocation growth mechanism . Theoretical studies using PBC theory HHM crystal morphology, analyzed and discussed the difference between the actual shape . Finally starting from the solution structure of HHM explored in different solvents crystal nucleation behavior, and changes in solute effect on nucleation .
