AMMONIUM SULFATE CAS N°: 7783-20-2

OECD SIDS
AMMONIUM SULFATE
2. PHYSICO-CHEMICAL DATA ID: 7783-20-2
DATE: 18.04.2006
2.1 Melting Point
Decomposition:
yes at >= 150 - 280 degree C
Remark:
On heating in an open system, the compound begins to
decompose at about 150 °C, yielding ammonium bisulfate
(NH4HSO4), and releasing NH3.
Complete decomposition at 336 to 357 °C.
Reliability: (2) valid with restrictions
data from standard reference book
Flag:
Critical study for SIDS endpoint
