| Hazard Information | Back Directory | [General Description]
Clear colorless to light brown liquid. | [Reactivity Profile]
2,4-D, N-BUTYL ESTER(94-80-4) is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. | [Air & Water Reactions]
Insoluble in water. | [Fire Hazard]
Flash point data for this chemical are not available. 2,4-D, N-BUTYL ESTER is probably combustible. | [Chemical Properties]
colourless liquid | [Uses]
2,4-D-1-butyl ester may be used as a reference standard for the determination of 2,4-D-1-butyl ester in soil samples by capillary high performance liquid chromatography with ultraviolet detection. | [Production Methods]
The commercial production of 2,4-D-butyl ester begins with purified 2,4-D acid, obtained via the standard phenoxyacetic acid route. The free acid is dissolved in water or a mixed solvent and then neutralised with butanol under controlled pH and temperature, forming the butyl ester. | [Mechanism of action]
Selective, systemic, absorbed through roots and increases biosynthesis and production of ethylene causing uncontrolled cell division and so damages vascular tissue. Synthetic auxin. | [Pesticide Type]
