Smectic phase (smectic) smectic liquid crystal structure is in a class with the closest of all the crystalline structure. Such liquid crystal, the rod-like molecules contained strong interactions rely vertical functional group provided to the major axis direction of the molecules, and are arranged in a layered structure and equal market butyl acrylate, molecular long axis perpendicular to the plane of the layer. In the layer, the molecular arrangement to maintain a large number of solid di orderly, but these layers are not 严格刚 of butyl acrylate, molecules may be present within the active layer, but can not travel between the layers, the results of such a flexible The two-dimensional molecular sheets can slide between each other, while the vertical direction of flow in layers will have difficulties. Thus, smectic liquid crystal generally in all directions are very viscous. For example: for azoxy anisole: CH3OC6H4 (NO) = NC6H4OCH3 In general, it should first select the prevailing conditions, so that the crystallization process can proceed to give crystals, and then optimize the conditions described above. The conditions are ripe, to conduct pilot and production. If it is the focus of theoretical studies may not be the same. If you are engaged in applied research, it is relatively difficult to select a solvent butyl acrylate purposes, the key point Chaka Salt Lake rock salt crystals that can be found through the use of this solvent butyl acrylate price saturation point, supersaturation point range is not good control. If you had a bad election saturation point, saturation is not enough or too difficult to crystallization, let alone raise the grain. Then you may want to consider the complex solvent, adjusted saturation range. So I think the main thing is the crystallization process crystallization process control at this time each condition is most important. Good control of the crystallization process, the crystallization process is completed about 60%.
