Preparation of trinitrosotrimethylenetriamine

Preparation of trinitrosotrimethylenetriamine

To a solution of 7 g of hexamethylenetetramine in 200 ml of ice and water, simultaneously a solution were added containing 15 g of sodium nitrite dissolved in 50 ml of water and 6 N hydrochloric acid at the rate required to maintain the pH 1. The mixture was held at 0° C for 30 min.  The precipitated trinitrosotrimethylenetriamine is collected washed with small amount of cold water yielding 50% of the product with melting point 106-107° C.

    Just tried this earlier and it worked great. Question- is this especially toxic or carcinogenic? I need to know for safety reasons.

        Sorry to bother, but one last thing.
        I couldn’t help but notice this molecule is quite similar to RDX (Exceptions obviously being the NO groups are NO2, and the nitrogens [+ the NO2 groups] are in the 2, 4, & 6 positions for RDX, as opposed to 1, 3 & 5 for this compound). Is there a possibility that the NO groups could be either converted or replaced to/with NO2 groups? Thanks!

          Thanks for your interest. Yes -NO groups could be converted to NO2 groups, however, the oxidation synthesis is complicated and performed with exotic chemicals (I believe with very concentrated hydrogen peroxide).
