5.Trichlorotert-butanol is volatile and easy to sublimate.It can be catalyzed by hydroxide ion in aqueous solution.
6.The stability is good at pH3, but decreases with increasing pH.The half-life of trichlorotert-butanol stored at 25ºC at pH7.5 is about 3 months.
7.At room temperature, 0.5% (W/V) of trichlorotert-butanol solution is nearly saturated, and if the temperature drops, crystals may be precipitated from the solution.
