Abstract: | The cobalt(II) salts of some alkanemono- and disulfonic acids have been prepared; all are new and most of them crystallized with six molecules of water. Their behaviour under heating has been studied by thermogravimetric analysis (TG) and differential thermal analysis (DTA). Most of them lose their water in several steps and some anhydrous salts melt; the decomposition begins at a temperature which depends upon the structure of the organic anion and it leads to residues, the composition of which depends on the surrounding atmosphere. |
