Abstract
Abstract The dehydration of magnesium acetate tetrahydrate was studied by simultaneous TG—DTG—DTA under various sealed atmospheres (open, quasi-sealed, and completely sealed). It had been reported for this salt that dehydration was a single-stage loss of water. In the case of quasi-sealed systems (29.8, 60 and 100 μmφ tungsten wires), however, stable monohydrate was obtained Mg(CH 3 COO) 2 · 4 H 2 O → Mg(CH 3 COO) 2 · H 2 O + 3 H 2 O Mg(CH 3 COO) 2 · H 2 O → Mg(CH 3 COO) 2 + H 2 O Monohydrate is easily removed from the apparatus, and identified by means of X-ray diffraction.
