Process of inhibiting scale formation with mixtures of thio-, oxygen or thio-oxygen phosphates and pyrophosphates

摘要

Mixtures of Thiophosphates, pyrophosphates containing both oxygen and sulfur, and oxygen phosphates are effective as scale inhibitors. The mixtures are synergistically more effective as scale inhibitors than each component individually.PPThese synergistic mixtures are also effective for other uses such as for inhibiting corrosion, particularly in aqueous and/or oxygenated systems.
