Abstract
Aminoethers are used as corrosion inhibitors in boiler systems in which a working fluid comprising water with an aminoether corrosion inhibitor is circulated from a heater to a utilization site at which the working fluid gives up energy and decreases in temperature. A preferred class of aminoethers are the alkoxytriethyleneglycol-tert-alkylamines such as methoxy triethyleneglycol-tert-butylamine.
Claims6
A closed loop boiler system having a circuit in which a working fluid comprising water and an aminoether corrosion inhibitor is circulated from a heater to a utilization site comprising a radiator and/or a heat exchanger at which the working fluid gives up energy and decreases in temperature in which the aminoether corrosion inhibitor comprises a diamino ether and an aminoether alcohol represented by the respective formulae:
- where x is an integer ranging from 2 to 6.
