From spirocyclic phosphate, 3,9-dichloro-2,4,8,10-tetraoxa-3,9-diphosphasprio [5.5]undecane-3,9-dioxide (SPDPC) and piperazine mixed in appropriate ratio in high speed universal grinder, no solvent and catalyst, spirocyclic piperazine phosphate was synthesized under the heat energy produced from the grinder rotating knife high-speed shear strength. The mole ratio of raw material and the mixing time were researched and the suitable reaction condition was identified. The result is SPDPC and piperazine were mixed 350 s in 1:2(n/n) and the fuzzy white powder yielded over 95%. The product’s structure was characterized by IR and NMR.
