Summary
-
1.
It has been shown that it is possible to bring about the isomerization of ethylcyclopentane into methylcyclohexane in the vapor phase in contact with aluminum chloride deposited in charcoal with a yield of 92% of the theoretical amount.
-
2.
At a space velocity of 0.3, the optimum temperature for this reaction lies in the range 120–125°.
-
3.
When the isomerization is carried out on petroleum ethylcyclopentane concentrated in the suitable gasoline fraction, the nature of the later has no significant effect on the course of the isomerization.
-
4.
On the basis of this observation, a method has been found for the catalytic synthesis of methylcyclohexane from petroleum ethylcyclopentane.
-
5.
Dry hydrogen chloride aids in the maintenance of the isomerizing propensity of aluminum chloride deposited on activated charcoal.
