| abstract |
The invention discloses a synthesis method of piperazine pyrophosphate metal salt. The molecular structural formula of the piperazine pyrophosphate metal salt is shown in formula (I), wherein M is metal Mg, Zn, Ni or Al. Since the molecular structure of piperazine pyrophosphate and piperazine polyphosphate is rich in hydroxyl groups, it is easy to absorb moisture and agglomerate. The piperazine pyrophosphate metal salt of the present invention, especially the zinc piperazine pyrophosphate, has good initial decomposition temperature and water resistance. |
