Value:
Method:
Test substance:
= 467 degree C
other: calculated from the entropy of formation of solid
(NH4)2SO4
other TS: 99.0% min Univar brand (NH4)2SO4 supplied by Ajax
chemicals, and 99.5% min Analar brand (NH4)SO4 supplied by
British Drug Houses.
Remark:
1) Boiling point of material of approximately 98.8% purity
(maximum boiling mixture). Impurities are (NH4)HSO4 and
H2SO4. Boiling point of pure material will be lower, as
will boiling point of material with increased impurity
content.
2) Literature reports of the boiling (or decomposition)
temperature vary from approximately 200 to 400°C, depending
upon the purity.
