<p>Crystallization of a crystallizable material is achieved through heat exchange in a plate heat exchanger is disclosed. A mixture or solution comprising a crystallizable material passed through a plate heat exchanger at an appropriate temperature and pressure such that the material is selectively crystallized. The processes are particularly useful in the production of para-xylene, dimethylnaphthalene, aromatic carboxylic acids, and aromatic anhydrides.</p> |
