アセチレン化合物の酸洗い抑制効果 (その2)

アセチレン化合物と界面活性剤との配合効果

抄録

The synergistic effect of some surface active agents on the corrosion inhibiting effect of two acetylenic compounds (i.e. propargyl alcohol and dipropargylthioether) in acid media were studied.
In the case of propargyl alcohol, it was found that the N-containing surface active agents, such as polyoxyethylene-amide and -amine, were most effective, and that non-ionic agents, such as polyoxyethylene-alkyl or -aryl ether and -sorbitane ester, were next to them and that anionic agents, such as SDS, DBS, aerosol-OT, were almost ineffective.
In the case of dipropargyl thioether, however, all of the surface active agents, if not decomposed in the corrosion environments examined, were found to be very effective.
Polarization characteristics also confirmed the experimental results.
