Storage Conditions:Refrigerator
Vapor Pressure:<0.1 mm Hg ( 55 °C)
Vapor Density:Relative vapour density (air = 1): 3.0
Toxicity:Oral-Rat LD50: 104 mg/kg; Oral-Mouse LD50: 105 mg/kg
Flammability characteristics:Inflammable in case of open flame, high temperature, oxidant; burning produces irritating smoke
Explosive limit:Explosive reaction with traces of alkalies, alkali earth hydroxides, halide salts, strong acids, mercury salts plus strong acids.
Henrys Law Constant:Henry's Law constant = 1.684X10-11 atm-cu m/mol at 25 °C (est)
Experimental Properties:SOLN IS STRAW TO AMBER COLOR|Hydroxyl radical reaction rate constant = 3.38X10-11 cu cm/molec-sec at 25 °C (est)
Air and Water Reactions:Soluble in water.
Reactive Group:Alcohols and Polyols
Reactivity Profile:Pure BUTYNEDIOL is non-explosive. Small amounts of certain impurities-alkali hydroxides, alkaline earth hydroxides, halides-may cause explosive decomposition upon distillation. Butynediol should not be treated with basic catalysts in the absence of a solvent at room temperature, and its stability is less with elevated temperatures. In strong acids, contamination with mercury salts can also result in violent decomposition. [NFPA 491M 1991].
Autoignition Temperature:335 °C
