Diethylhydroxylamine (DEHA) - 85%

DEHA 85% solutions is available as a yellow liquid with an amine-like odor. DEHA products are manufactured by the reaction of a triethylamine and a peroxide, followed by purification and distillation. Eastman manufactures DEHA Anhydrous and DEHA 85%.

Both DEHA Anhydrous and DEHA 85% function primary as radical and oxygen scavengers.


DEHA is used in boiler water treatment applications, as an oxygen scavenger for medium and high pressure boilers. DEHA also functions as a free radical scavenger in polymerization, it is a short stopper in the production of styrene butadiene rubber.


Beyond its application as scavenger, DEHA is also used in refinery chemicals and other niche markets, such as:


- Microelectronics industry: for example, DEHA is formulated to remove residual photoresist and other residue from microelectronic parts.

- Photographic industry: DEHA is blended with other chemicals to produce good color development.
