Stability of dehydracetates of metals of the 2nd group

Stability constants of magnesium, calcium, strontium and barium complexes with dehydracetic acid were as certained by the method of pH-potentiometric titration. The complexes, as well as beryllium complexes, are isolated in solid form, their resistance to thermal effect and electron shock was considered. A high volatility of beryllium compound with a decrease in pressure was revealed. Its fragmentation under conditions of mass-spectrometric analysis differs from the one characteristic of magnesium dehydracetate
