Abstract
A series of high-density 7-(N-methyl-N-alkylamino)-1,3,5 triazaadamantanes re prepared. The preparation involves first adding the alkyl group to the parent amine by reacting the amine with a suitable aldehyde and hydrogen in the presence of a platinum catalyst and then reacting the thus produced secondary amine with formaldehyde and hydrogen in the presence of a nickel catalyst to produce the final product. The series represents a new class of fuels which is particularly useful in volume-limited applications.
Claims2
A compound represented by the formula:
- ##STR3## wherein R is an alkyl selected from the group consisting of C.sub.2 H.sub.5, C.sub.3 H.sub.7, C.sub.4 H.sub.9, C.sub.5 H.sub.11, C.sub.6 H.sub.13, and C.sub.7 H.sub.15.
A method for preparing 7-(N-methyl-N-alkylamino)-1,3,5-triazaadamantanes comprising the steps of:
- 1. preparing 7-nitro-1,3,5-triazaadamantane by adding nitromethane and paraformaldehyde to a refluxing solution of ammonium acetate in ethanol;
- 2. preparing 7-amino-1,3,5-triazaadamantane by reacting 7-nitro-1,3,5-triazaadamantane with hydrogen in the presence of a rhodium-charcoal catalyst;
- 3. preparing 7-(N-alkylamino)-1,3,5-triazaadamantane by reacting 7-amino-1,3,5-triazaadamantane with an aldehyde and hydrogen in the presence of a platinum catalyst;
- and
- 4. preparing the final product by reacting 7-(N-alkylamino)-1,3,5-triazaadamantane with formaldehyde and hydrogen in the presence of a nickel catalyst.
