METHOD AND APPARATUS FOR THE PREPARATION OF TRIPTANE AND/OR TRIPTENE

摘要

A continuous or semi-continuous process for the production of triptane and/o r triptene from methanol and/or dimethyl ether in the presence in a reactor of an effective concentration of catalyst active for the conversion of methanol and/or dimethyl ether to triptane and/or triptene in which process co-produc ed water is separated from the catalyst as a vapour phase whilst the catalyst i s retained in a liquid or solid phase. Preferably, the catalyst comprises zinc halide and is maintained in said reactor in an active form and an effective concentration. Apparatus for use in the process may comprise a reactor havin g at least one reaction zone and at least one separation zone.
