摘要：

Conditions in which a composite chromium tanning agent can be obtained in the presence of glyoxal were studied. It was found that the expenditure of the aldehyde and sulfuric acid affects the reduction kinetics of hexavalent chromium. Spectrophotometry and conductometry were used to examine the composition of composite tanning agents. It was shown that chromaldehyde tanning agents can be applied in manufacture of leather and fur.
