| titleOfInvention |
Prevention of polymer formation in dehydrogenation of p-ethyltoluene |
| abstract |
In the catalytic dehydrogenation of p-ethyltoluene to p-methylstyrene, popcorn polymer forms and builds up in the condenser, shortly plugging it. This is prevented by adding minor amounts of H 2 S continuously to the gaseous product effluent entering the condenser. |
