Crystallization fit是什么
WebThe rate of crystallization should not exceed values that cause too much uptake of solvent via inclusions. For a cooling crystallization, natural cooling profiles should be avoided, as most of the material crystallizes too fast. Linear cooling rates are a first approximation. The rates can be classified as slow, realistic, fast and crash ... WebFeb 2, 2011 · Crystallization is used industrially in a wide variety of processes. Typical applications include bulk chemicals, such as salt, sugar and fertilizers; high value-added products such as specialty chemicals and pharmaceuticals; and difficult separations such as ortho- and para-xylene.

WebAll crystallization processes are aimed at creating a supersaturated solution or melt. The su-persaturation is the driving force under whose in uence new crystals are formed and present crystals grow. This is illustrated in gure 1 where a typical cooling crystallization experiment in shown together with the solubility line. WebApr 7, 2024 · Along with increased purity, a slow crystallization process also encourages the growth of larger crystals. Figure 3.17 shows crystallization of acetanilide from water with two different rates. The crystals grown in Figure 3.17a were formed much more quickly, and are smaller than the slower grown, larger crystals in Figure 3.17b.
