2-sec-butyl-4,6-dinitrophenol, compound with 2,2'-iminodiethanol (1:1) Chemical Properties, Uses, Production
Production Methods
Dinoseb diolamine was manufactured through the same foundational sequence used for other dinoseb salts, with the distinguishing step being neutralisation by a secondary amine rather than ammonia or alkali. Producers first generated technical grade dinoseb by mixed acid nitration of 2 tert butylphenol, followed by removal of tarry by-products and residual acids to stabilise the nitrophenolic intermediate. The purified dinoseb was then reacted with diethanolamine in a controlled, typically aqueous or hydroalcoholic medium. This step formed the diolamine salt through simple acid-base neutralisation, with process conditions tuned to prevent oxidative darkening and to keep the viscous amine manageable. The resulting dinoseb diolamine was subsequently formulated.
Mechanism of action
Inhibits respiratory electron transport, and uncouples oxidative phosphorylation - membrane disruption. Selective, non-systemic. Contact action.
Pesticide Type
Herbicide
