ABSTRACT:
The plugging of conduits containing a mixture of low-boiling hydrocarbons and water in inhibited by adding to the mixture an effective amount of at least one alkylated compound of the general formula formula ##STR1## wherein R.sub.1 and R.sub.2 each are independently chosen from normal or branched alkyls containing a chain of at least 4 carbon atoms,
R.sub.5 is an organic moiety containing a chain of at least 4 atoms,
X is S, N--R.sub.4 or P--R.sub.4,
R.sub.4 is H or an organic substituent, suitably an alkyl or alkenyl group having from 8 to 20 carbon atoms, and
Y-- is an anion.
