Chlorine‐Containing compounds as copper catalyst poisons
The effect of chlorine‐containing substances on the rate of the copper chromite‐catalyzed hydrogenation of soybean oil has been investigated. Using chlorinated soybean oil as a model substance, it was found that amounts corresponding to 25, 50 and 90 ppm Cl markedly decreased the rate of hydrogenati...

| Summary: | The effect of chlorine‐containing substances on the rate of the copper chromite‐catalyzed hydrogenation of soybean oil has been investigated. Using chlorinated soybean oil as a model substance, it was found that amounts corresponding to 25, 50 and 90 ppm Cl markedly decreased the rate of hydrogenation when added to a 0.5% Cu run at 170 C. Similar effects were found with various chlorinated alkanes. It was also found that the refined and bleached soybean oil contained noticeable amounts of an unknown catalyst poison. This made if difficult to calculate specific poisoning constants for chlorine (% Cu/ppm Cl). Attempts have been made to estimate minimal values for this constant. |
