Embodiment 1
[0014] Embodiment 1: the preparation of free 2,2'-bis[[4-(isopropoxy)phenyl]methylene]-diaminoguanidine:
[0015]
[0016] Take 100g of 2,2'-bis[[4-(isopropoxy)phenyl]methylene]-diaminoguanidine hydrochloride (water content about 15%), add 750ml of 95% ethanol, add 12.5g of NaOH, 2, 2'-bis[[4-(isopropoxy)phenyl]methylene]-diaminoguanidine gradually dissolved and NaCl was precipitated. Stir for 0.5h and filter with suction. The filtrate was added dropwise to 3L of water, and a solid was precipitated. Suction filtration, the obtained solid was dried at 45 degrees to obtain 70g product (2,2'-bis[[4-(isopropoxy)phenyl]methylene]-diaminoguanidine).
