Y zeolite catalyst |
| abstract |
A catalyst comprising a Y zeolite of which silica/alumina molar ratio ranges from 15 to 110, use of this catalyst for alkylation of monoisopropylnaphthalene and a method for preparation of this catalyst comprising treating a Y zeolite with an acid(s) to adjust the silica/alumina molar ratio to 15 to 110 are disclosed. A method for preparation of mono and/or diisopropylnaphthalenes comprising reacting naphthalene and/or monoisopropylnaphthalene with propylene in the presence of at least one saturated polycarbocyclic compounds and a catalyst comprising a Y zeolite having the silica/alumina molar ratio of from 10 to 350 are disclosed. This catalyst makes possible the production of β-monoisopropylnaphthalene in good yield by alkylation of naphthalene and the production of β-monoisopropylnaphthalene and/or 2,6- and 2,7-diisopropylnaphthalenes in good yield by alkylation of naphthalene and/or monoisopropylnaphthalene in good percent conversion. |
