摘要：

The influence of organic solvents on the habit of organic crystals was examined experimentally. The differences in two physical properties such as heats of crystallization between the solution and the crystallizing component and dipole moments between the solvent and the crystallizing components were proposed as measures of the discrepancy from ideal behavior of the mixtures. The crystal shapes of m-chloronitrobenzene and 2-methyl-4-nitroaniline were classified into three types: one-dimensional (needle-like), two-dimensional (plate-like) and three-dimensional (prismatic) crystals. It was found that well defined three-dimensional crystals were formed from the solutions with solvents which provide ideal solubilities and possess similar values of dipole moments. © 1990, Elsevier Science Publishers B.V..
