XLogP3:3.33
Appearance:3,4-dichlorophenol appears as needles (from benzene, petroleum ether) or light brown and yellow crystals. Odor threshold 100 µg/L. Taste threshold 0.3 µg/L in water. (NTP, 1992)
Density:1.5±0.1 g/cm3
Melting Point:68 °C
Boiling Point:253 °C
Flash Point:109.1±15.8 °C
Refractive Index:1.594
Water Solubility:In water, 9,260 mg/L at 25 deg C
Storage Conditions:0-6ºC
Vapor Pressure:1.73X10-2 mm Hg at 25 deg C (est)
Explosive limit:During vacuum fractionation of the mixed dichlorophenols produced by partial hydrolysis of trichlorobenzene, rapid admission of air to the receiver caused the column contents to be forced down into the boiler at 210 deg C, and a violent explosion ensued. /Dichlorophenol mixed isomers/
Taste:Taste threshold in water: 0.3 ug/l
Henrys Law Constant:Henry's Law constant = 3.08X10-7 atm-cu m/mol at 25 °C (est)
Dissociation Constants:pKa = 8.63
Experimental Properties:Aqueous solutions of Fenton's reagent iron (2+)+ hydrogen peroxide have been used to affect the total decomposition of the chlorophenols: 2-chlorophenol, 3-chlorophenol, 4-chlorophenol, 3,4-dichlorophenol and 2,4,5-trichorophenol. The mineralization of these chlorinated aromatic substrates to carbon dioxide and free chloride has been studied as a function of iron (2+)+ hydrogen peroxide and perchloric acid. Increasing the concentration of iron (2+)+ hydrogen peroxide enhances the decomposition process, while an increase in the concentration of perchloric acid, inhibits the reaction. The presence of iron (3+) alone without any iron (2+) with hydrogen peroxide has no effect on the degradation of the chlorophenols. In all cases, the stoichiometric quantity of free chloride was obtained at the completion of the decomposition reaction; but the rates of disappearance of the chlorophenol and of the formation of the chloride are not similar.|Hydroxyl radical reaction rate constant = 6.99X10-12 cu cm/molec-sec at 25 °C (est)
Air and Water Reactions:Insoluble in water.
Reactive Group:Phenols and Cresols
Reactivity Profile:3,4-DICHLOROPHENOL is incompatible with acid chlorides, acid anhydrides and oxidizing agents. (NTP, 1992)
