Abstract
A method for treating in an industrial water treatment system for at least two of metal corrosion inhibition, scale inhibition, suspended matter dispersion, biocide efficacy, or biofilm removal/biofilm dispersion is taught by the use of at least one compound which is a salt derived from a thioamine or an oxyamine and an acid.
Claims5
A compound of the formula of Formula (IA) below:
- [R—X—R1—NH3+]zQ−z Formula (IA)
- wherein:
- R is a straight-chain or branched-chain C6-C24 alkyl or a straight-chain or branched-chain C6-C24 alkyloxy-C2-C3-alkyl;
- X is S or O:
- R1 is a straight-chain or branched-chain C2-C3 alkyl;
- z is a integer of at least 1 such that the compound of Formula (IA) is electrically neutral;
- and
- Q is an anionic moiety derived from an acid having one or more acidic hydrogens, and has three or more groups capable of coordination to metal cations or electron-deficient sites on a metal surface, selected from the group consisting of the anions from:
- (1-hydroxyethan-1,1-diyl)bis(phosphonic acid);
- provided that the compound of Formula (IA) is a solid wherein the compound of Formula (IA) is less soluble in water than its acid used to derive the Q anion.
