Claims
- 1. A process for isomerizing alkylthiophenes, which process is carried out in the gaseous phase at temperatures from about 300.degree.-450.degree. C., which comprises contacting an alkylthiophene or a mixture of alkylthiophenes with an acid zeolyte catalyst of the pentasil type.
- 2. The process as claimed in claim 1, wherein the alkylthiophene is a methylthiophene.
- 3. The process as claimed in claim 1, wherein the alkylthiophene is an ethyl thiophene.
- 4. The process as claimed in claim 1, wherein the catalyst is H-ZSM-5.
- 5. The process as claimed in claim 1, wherein the alkylthiophene is 2-methylthiophene.
