| 摘要 |
Selective reactions of hydrocarbons and/or oxygenated hydrocarbons are conducted in the presence of catalysts comprising one or more zeolites characterized by a silica to alumina mole ratio of at least 12 and a constraint index in the approximate range of 1 to 12, said catalysts are contacted with bulky heterocyclic organic nitrogen compounds. Said nitrogen compounds have an effective critical dimension of greater than 6.2 Angstroms and a pKa of between about 3 and 9. The process of this invention is particularly useful in the production of dialkylbenzene derivatives low in the ortho-isomer. |
