STUDIES ON THE REACTIONS OF SELENITE ION WITH 1,2-DIMERCAPTOETHANE OR THIOACETIC ACID

Article abstract of DOI:10.1016/0040-4020(82)87021-X

The reactions are reported between selenite and 1,2-dimercaptoethane (DME) or thioacetic acid (TAA) to form moderately stable derivatives having an enhanced absorptions in the 230-360 nm region in combining molar ratios 3:2 and 4:1, respectively.Both reactions invariably yield one product corresponding to the selenium-containing derivative of DME or TAA.The formation of products is a pH dependent process.The equilibrium constants of reactions between selenite and DME or TAA were measured.
