Conclusion
It should be stressed again that successful hydrogenation depends upon the careful preparation and handling of all materials, the accurate control of the reaction, and the use of efficient equipment and operating procedures. Our understanding of the reaction and the chemistry involved is far from complete and present methods of controlling the results are, by necessity, indirect and time-consuming.
The critical problem of hydrogenation has to do with the selectivity of the reaction. Improvements in the process therefore will depend largely upon the preparation of better and more selective catalysts. Perhaps when catalysts are developed which will provide very precise selectivity, continuous methods for hydrogenation may be used to much greater advantage.
