Bisulfite reaction
WebThe reaction of bisulfite with oxygen is typically faster at higher temperatures and can be facilitated by transition metal ion catalysts, e.g. Cobalt (II). Applications. The most common applications of oxygen scavenger in oil and gas production are for seawater injection facilities, hydro-testing, and acid stimulation. WebOct 16, 2024 · In the present work, the bisulfite reaction with Ψ was explored to identify six isomers of bisulfite adducted to Ψ. We found four of these adducts involved the heterocyclic ring, similar to the reaction with other pyrimidines. The remaining two adducts were bonded to the 1' carbon, which resulted in opening of the ribose ring.
