Abstract
Hide powder was tanned with various kinds of masked chromium chloride solutions and components separated from the masked chrome solutions. T he thermal stability of the tanned hide powders was studied by DSC. Th e thermal stability varied with the bind and amount of chromium comple xes fixed by hide powder. Formato- and acetatochromium complexes with charges corresponding to +2 and +3 had a much greater effect on the th ermal stability. Cationic oxalatochromium complexes also had a conside rable effect, but anionic oxalatochromate complexes had little effect.
