| Abstract: | Investigations into the efficiency of benzyl-n-propyl sulfide as a corrosion inhibitor in acid solutions Investigations made so far into thioethers have shown that benzyl and phenyl sulfides, though being comparable from a structural point of views, may have very different inhibiting effects in the system iron-mineral acid. An attempt has therefore been undertaken to obtain further information about sorption and inhibition processes by using benzyl-n-propyl sulfide labelled with 35S. The protective effect of benzyl-n-propyl sulfide has been determined in sulfuric and hydrochloric acids under varying conditions of concentration, time, temperature and anions present, and the amount of inhibitor adsorbed to the metal surface was simultaneously measured. Other measurements were concerned with the adsorption of labelled anions from pickling acids with and without inhibitor. |
