XLogP3:2.70
Appearance:Crystals or white powder. (NTP, 1992)
Density:1.9671 (rough estimate)
Melting Point:112-114 °C(lit.)
Boiling Point:318.1±42.0 °C(Predicted)
Flash Point:146.2±27.9 °C
Refractive Index:1.5230 (estimate)
Water Solubility:1-5 g/100 mL at 21 ºC
Storage Conditions:Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
Vapor Pressure:0.004-0.081Pa at 25-40℃
PKA:11.91±0.10(Predicted)
Air and Water Reactions:Water soluble.
Reactive Group:Alcohols and Polyols
Reactivity Profile:A halogenated alkene and alcohol. The unsaturated aliphatic hydrocarbons are generally much more reactive than the alkanes, which are saturated aliphatic hydrocarbons. Strong oxidizers may react vigorously with them. Reducing agents can react exothermically to release gaseous hydrogen. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
Critical Temperature & Pressure:Storage temp. 2-8°C
