Photolytic. Peijnenburg et al. (1992) investigated the photodegradation of a variety of substituted aromatic halides using a Rayonet RPR-208 photoreactor equipped with 8 RUL 3,000- ? lamps (250–350 nm). The reaction of 1,3,5-tribromobenzene (initial concentration 10-5 M) was conducted in distilled water and maintained at 20 °C. Though no products were identified, the investigators reported photohydrolysis was the dominant transformation process. The measured pseudo-first-order reaction rate constant and corresponding half-life were 0.005/min and 140.5 min., respectively.
Chemical/Physical. 1,3,5-Tribromobenzene will not hydrolyze to any reasonable extent.

Crystallise it from glacial acetic acid/water (4:1), then wash with chilled EtOH and dry in air. [Beilstein 5 H 213, 5 IV 685.]
