Prevention of polymer formation in dehydrogenation of p-ethyltoluene |
| abstract |
PREVENTION OF POLYMER FORMATION IN DEHYDROGENATION OF p-ETHYLTOLUENE ABSTRACT A method for the catalytic dehydrogenation of p-ethyltoluene to p-methylstyrene in which the formation of proliferous polymer in the condenser is prevented by adding minor amounts of H2S continuously to the gaseous product effluent entering the condenser. |
