Thermal behaviour of pharmacologically active lithium compounds

The thermal decompositions of a series of simple lithium compounds (carbona te, sulfate, acetate, citrates, aspartates and glutamates) currently used i n the treatment of manic-depressive psychosis and related disorders were in vestigated by means of TG and DTA measurements in oxygen atmosphere. Pyroly sis residues were characterized by infrared spectroscopy. The stabilities o f the hydrates and intermediate phases generated during the degradation pro cesses are discussed.
