Claims15
An aqueous composition for inhibiting the corrosion of metals placed therein comprising:
- (a) an effective amount of a corrosion-inhibiting compound having the formula:
- ##STR6## where R.sub.1 and R.sub.2 are independently alkyl C.sub.1 -C.sub.6 ;
- and (b) a non-oxidizing acid.
A compound of the formula:
- ##STR7## where R.sub.1 and R.sub.2 are alkyl C.sub.1 -C.sub.6.
A corrosion inhibitor for aqueous solutions of mineral acids consisting essentially of the reaction product obtained by the catalytic ethynylation of a di(higher)alkylamine ##STR8## where R.sub.1 and R.sub.2 are independently alkyl C.sub.1 -C.sub.6, and benzaldehyde, with acetylene.
