no data available
10.3 Possibility of hazardous reactions
Combustible when exposed to heat or flame.1,2,4,5-TETRACHLOROBENZENE is incompatible with strong oxidizing agents. Reacts violently with sodium hydroxide in methanol. Several explosions have occurred during alkaline hydrolysis. (NTP, 1992)
10.4 Conditions to avoid
no data available
10.5 Incompatible materials
Serious accidents have occurred during the commercial preparation of 2,4,5-trichlorophenol by alkaline partial hydrolysis of 1,2,4,5-tetrachlorobenzene during the period 1949 to 1976 ... The earlier process used methanolic alkali under autogenous pressure to effect the hydrolysis, and on 2 occasions around 1949 the reaction at 125 deg C went out of control, one attaining 400 deg C. ... In a further incidents in 1953, the explosion was associated with the post reaction stage during distillation of methanol from the reaction mixture. The later process used ethylene glycol as solvent to effect hydrolysis with sodium hydroxide and operated essentially at or near atmosphere pressure. ... Violent decomposition could ... occur during the subsequent solvent distillation phase in the absence of effective temp control. A laboratory residue from vacuum stripping using electric heating (without knowledge of the liquid temp) exploded when the vapor temp had reached 160 deg C. In the Coalite plant incident in 1968, where the hydrolysis was run at about 180 deg C in a reaction vessel heated by circulating oil at 300 deg C, failure of the manually regulated oil heating system led to an uncontrollable temp incr during 50 min to above 250 deg C, when a violent explosion occurred.
10.6 Hazardous decomposition products

12.2 Persistence and degradability
Using the Warburg technique, 1,2,4,5-tetrachlorobenzene was not biologically-oxidized by benzene-acclimated activated sludge at a concn of 500 ppm over 192 hr of incubation(1). Microbial decomposition of 1,2,4,5-tetrachlorobenzene by a Pseudomonas sp. or by a mixed culture of soil bacteria yielded 2,3,5,6-tetrachlorophenol(2,3). An analysis of monitoring data from sediment cores indicated insufficient evidence to show occurrence of anaerobic dehalogenation of tetrachlorobenzene in Lake Ontario sediments(4). Anaerobic incubation of 1,2,4,5-tetrachlorobenzene with mixed primary sewage sludge for 32 days reduced its concn by 61%(5).
