The unit processes directly apply to industry connecting, H E seventh Symposium on Unit Processes was held under as they do, basic chemistry with equipment and economics. the auspices of the Division of Industrial and Engineering CHEMICAL This chemical engineering aspect has been well supported by Chemistry at the Buffalo meeting of the AMERICAN SOCIETY.The fundamental object of these symposia is to researchers in a number of our university laboratories, as gather sufficient data to place a more quantitative foundation exemplified by most of the papers presented a t these symposia. The paper by Weinrich (page 264) is particularly under industrial chemical procedures. It would be desirable to have formulas into which, by substitution of the proper data welcome because it is a contribution from one of our large and evaluation thereof, answers would be forthcoming to industrial organizations. It is to be hoped that more of the give an indication of the proper procedures for the manuchemical companies will study and publish in these fields. Contributions from industry might well present the facture of chemicals. It is too much t o hope for such formulation in the very near future, but it is a t least the goal of general principles underlying the choice of equipment for a given unit process, such as design and applicability of the many working in unit processes. The unit process conception enables much related knowlapparatus for carrying on the unit process. This tie-in of chemical change with equipment needed to commercialize the edge to be classified under its appropriate head of alkylation, oxidation, hydrogenation, and the like. Perhaps when reaction, brings in the other member of the partnership beenough data have accumulated, certain formulation can be tween unit processes and unit operations, laying emphasis upon heat transfer, agitation, and other physical changes. attempted. At least we can hope for this goal in the kinetics and equilibria of the basic chemistry involved. R. NORRISSHREVE 263
