AI Article Synopsis
- Three different thiadiazole derivatives were synthesized to study their effectiveness as corrosion inhibitors for N80 carbon steel in CO-saturated oilfield produced water.
- The results showed that these compounds significantly reduced corrosion, with their effectiveness ranked as follows: BTT > BBT > BMT.
- The high performance of BTT is theorized to be due to its tautomeric transformation from thiol to thione.
Article Abstract
Three thiadiazole derivatives with different substituent groups, 2-(benzylthio)-5-methyl-1,3,4-thiadiazole(BMT), 2-(benzylthio)-5-(butylthio)-1,3,4-thiadiazole(BBT), and 5-(benzylthio)-1,3,4-thiadiazole-2-thiol(BTT), were synthesized and studied as the corrosion inhibitors for N80 carbon steel in CO-saturated oilfield produced water. It is found that the synthesized thiadiazole derivatives could effectively inhibit the corrosion of N80 carbon steel by chemisorption. The corrosion inhibition performance of the organic compounds is in the order: BTT > BBT > BMT. The theoretical calculations indicate that the tautomeric transformation from thiol-BTT to thione-BTT may be responsible for the high inhibition performance of BTT.
