Reaction Engineering Approach to Crystallization: Rate Process Intensification in Dissolution-Crystallization Reactions

这一建议努力表征的溶解和结晶的机制，当一个少溶性盐是由颗粒物质的溶解产生。特别是，这项工作的重点是通过使用微相来加强这一私人过程。最近的研究表明，非常小的颗粒或晶体的存在可以提高从一个相到另一个相的传输速率。这项工作的独特之处在于不会添加外部产生的微相，而反应本身会产生微相。这个过程被称为反应结晶；反过来，它属于一种叫做“过程强化”的研究。从反应工程的观点来研究结晶是一种趋势的一部分。另一个挑战是对所涉及的复杂相互作用进行理论分析，然后将其应用于溶解沉淀过程的设计。

This proposal strives to characterize the mechanism of dissolution and crystallization when a sparingly soluble salt is produced from the dissoultion of particulate material. In particular, the work focuses on the intensification of tis prate process by the use of microphases. The presence of very small particles or crystallites has been recentl shown to enhance the rate of transport from one phase to another. The unique aspect of this work is that no externally produced microphase will be added, and the reaction itself will produce the microphase. This process has been termed reaction crystallization; and it, in turn, falls under a class of research called "process intensification". It is part of a trend to approach crystallization studies from a reaction engineering point of view. On additional challenge to develop theoretical analysis of the complex interactions involved and then apply them to the design of dissolution - precipitation processes.
