The ternary system CH3CO2Na–Na4P2O7–H2O was investigated between 38 and 85°C. No double salt occurs in this temperature range. The saturated CH3CO2Na solutions can contain only small amount of Na4P2O7. The CH3CO2Na solutions have a very strong dehydrating influence on Na4P2O7·10H2O. So, the lowest formation temperature of anhydrous Na4P2O7 is about 47°C.
