WebJun 22, 2024 · The flow-induced crystallization (FIC) is commonly encountered in the polymer industry as more than 70% of commercial polymers are crystalline, which needs to be processed before the final application.
WebJan 6, 2024 · On the other hand, crystallization-induced deracemization is simple to implement and to scale up because of its analogy with cooling crystallization processes (e.g., preferential crystallization). However, its productivity strongly depends on solubility and high product purity can be attained only if it is possible to avoid distomer nucleation. dyson dc24 brush bar not turningCrystallization is the process by which solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.
