  • Selective alkylation of xylenes with ethylene
    Patent number: 4584422
    Abstract: A process for the production of 3,4-dimethyl-1-ethylbenzene by selective alkylation of dimethylbenzene with ethylene. The process is carried out in the presence of a crystalline zeolite catalyst having a silica to alumina mole ratio of at least about 12 and a Constraint Index of greater than 2 and up to about 12.

  • Selective alkylation of aromatic hydrocarbons using a mixed ethylene/propylene alkylation agent
    Patent number: 4387259
    Abstract: Aromatic hydrocarbons are selectively alkylated using an alkylating mixture containing both ethylene and propylene. By employing a zeolite ZSM-12 based alkylation catalyst, essentially only the propylene from the olefin-containing alkylation mixture will react with the aromatic hydrocarbon to thereby form both an alkylaromatic product enriched in propylated alkylaromatic and a propylene-free residual olefin-containing mixture enriched in the unreacted ethylene.
