Abstract
Tetrahydrodimethyldicyclopentadiene is catalytically isomerized to a liquid isomeric mixture having a suitable low temperature viscosity making it suitable as a missile fuel. The catalyst comprises an acidic alumina. Hydrogen is also present and in an amount sufficient to maintain the isomerization activity of the alumina. The elevated temperature is sufficient to cause isomerization.
Claims10
Process for the catalytic isomerization of endo tetrahydrodimethyldicyclopentadiene comprising:
- (a) contacting endo tetrahydrodimethyldicyclopentadiene with a catalytic amount of acidic alumina having isomeric activity;
- (b) having the contacting occur at an isomerization temperature in the range of from about 100.degree. C. to about 400.degree. C. and in the presence of sufficient hydrogen to maintain the isomeric activity of the alumina;
- and
- (c) continuing the contacting until the endo diene is isomerized to its exo isomer.
