摘要
The control of crystal shapes by melting are attempted, and melting phenomena of the organic compound crystals in a melt with the secondary components are discussed. The melting rates of an m-chloronitrobenzene (CNB) mother crystal in an m-/p-CNB melt were measured for various p-CNB compositions in a melt, and the shapes of a melted m-CNB mother crystal were observed. The melting rates of an m-CNB mother crystal for various directions were not zero and fluctuated with experimental duration. The ratios of the melting rate of an m-CNB mother crystal for they direction relative to x direction were varied with the p-CNB compositions in an m-/p-CNB melt. Adsorption and desorption of p-CNB occur on the surfaces of the m-CNB mother crystal in the m-/p-CNB melt during melting, and the difficulty of adsorption and desorption of p-CNB changes according to the respective faces of the m-CNB mother crystal.
