<p>
</p><p class="MsoNormal"><font size="4"><span>While the first step
of chemical investigations is often the synthesis of a new product, a careful
analysis quickly forces us to deal with issues concerning the purity of the
product, the amount of product, or, especially in chemical engineering
contexts, the cost of the product obtained. Addressing these issues, directly
leads us to the formulation of one or more objective functions that need to be
optimized during the synthesis process. A common approach to solve such
problems consists in performing many experiments with carefully chosen sets of
synthesis parameters and then using statistical analyses to find optimal sets of
these parameters. However, in many cases, it is possible to write down
(phenomenological) rate equations that describe the processes involved in the
development of the chemical system. This allows us to formulate analytical
objective functions as function of state and control variables, casting the
optimization of the chemical synthesis into the language of optimal control.[1-4]</span></font></p><font size="4">

</font><p class="MsoNormal"><font size="4"><span>In this talk, I am
going to present a number of examples of the application of optimal control
methods to the optimization of chemical processes, such as the optimization of a
liquid-gas phase transition,[3] the optimal control of homogeneous nucleation
and growth of crystals,[4] and the optimal control of the transfer of a
chemical system between different crystalline modifications.[5]</span></font></p><p class="MsoNormal"><font size="4"><span><br></span></font></p><p class="MsoNormal"><font size="4"><span>
