Novel sulfonium corrosion inhibitors in aqueous acid solutions |
| abstract |
The corrosion of metal surfaces in contact with aqueous acid cleaning solutions is inhibited by sulfonium salt corresponding to the formula <IMAGE> <IMAGE> wherein n is 1 or 2; R1 is an electron withdrawing group; R2 is a hydrocarbyl radical or inertly-substituted hydrocarbyl radical of up to about 24 carbon atoms; R3 is alkyl of from 1 to 4 carbon atoms, inertly-substituted alkyl of 2-4 carbon atoms, allyl, phenyl or inertly-substituted phenyl; or R2 and R3 are joined to form a 5- or 6-membered heterocyclic ring; and A<-> is a compatible anion. These sulfonium salts are effective corrosion inhibitors even in the presence of ferric ions. |
