Brown Hydrogenator generates catalyst in situ, operates at ambient pressure Simple, a u t o m a t i c h y d r o g é n a t i o n without high pressures and temperat u r e s — t h e s e are t h e o u t s t a n d i n g characteristics of the new Brown Hydrogenator. V a l u a b l e in o r g a n i c s y n t h e s i s , analysis, and studies of hydrogénation rates and catalysis, the unit was developed by Dr. H. C. Brown and C. A. Brown, a father-and-son team at Purdue University. The Brown unit provides in situ generation of platinum catalysts for hydrogénation, avoiding the hazards ordinarily involved in adding these highly active catalysts to organic solvents. After catalyst formation, the u n i t g e n e r a t e s h y J r o g e n for t h e hydrogénation reaction. A unique valve controls the rate of hydrogen generation to maintain the hydrogénation flask at essentially atmospheric pressure. The valve closes automatically when hydrogénation is complete. Two models of the unit are availa b l e : o n e p r o v i d e s g e n e r a t i o n of hydrogen directly in the hydrogénation flask; the other has a separate flask for generating hydrogen.
