Catalyst Screening During the Last Decade

The first uses of microtechnology for screening applications were presented recently. For instance, Watts and Haswell [2] presented first work on microfluidic combinatorial organic chemistry. Most of the examples described apply to glass, polymer or silicon reactors, which restricts their usage to low-pressure operation similar to pharmaceutical applications. They concluded that micro reactors could be a tool for rapid reaction development and process optimization. 

In the following, the major aspects of current screening in the sequence of its workflow will be discussed and unsolved issues are pointed out
