Abstract
A method of synthesizing and isolating N-(bromoacetyl)-3,3-dinitroazetidine (ABDNAZ) by reacting DNAZ with bromoacetyl bromide and boron trifluoride etherate to produce a mixture comprising ABDNAZ and a salt of DNAZ. Water and a solvent are added to the mixture to form an organic phase comprising the ABDNAZ and an aqueous phase comprising the salt of DNAZ. The organic phase and the aqueous phase are separated to produce an ABDNAZ/solvent solution comprising the ABDNAZ and the aqueous phase comprising the salt of DNAZ. A nonsolvent is added to the ABDNAZ/solvent solution to produce an ABDNAZ/solvent/nonsolvent mixture. The ABDNAZ is subsequently recovered. A composition comprising ABDNAZ is also disclosed.
