N,N-Diethyl Hydroxyl Amine (DEHA) – CAS 3710-84-7

This product is an advanced water treatment solution based on N,N-Diethyl Hydroxylamine (DEHA), typically supplied as an approximately 85% w/w aqueous solution. Designed as a highly effective oxygen scavenger, it diligently removes dissolved oxygen from boiler feedwater, significantly preventing corrosion and pitting. Its volatile nature ensures comprehensive protection throughout the entire steam and condensate system. Beyond oxygen scavenging, it acts as a passivator, forming a protective film on metal surfaces, and also aids in maintaining optimal pH levels. This clear, colorless to pale yellow liquid delivers robust corrosion inhibition and metal passivation for various systems.
