CONVERSION OF ETHERS Process of converting aliphatic ethers, particularly alkyl ethers, to other desirable products by contacting such with a crystalline aluminosilicte molecular sieve catalyst having a constraint index of about 1 to 12 and a silica to alumina ratio of at least about 12 at elevated temperature. The catalyst preferably has a crystal density in the hydrogen form of not substantially below about 1.6 grams per cubic centimeter. Products produced by such conversion vary with temperature, with conversion to aromatic rings and substituted aromatic rings predominating at higher temperatures of about 500 to 1000.degree.F. |
