Hazard Predictions

ALUMINUM BROMIDE is deliquescent and fumes in moist air. The reaction with water is vigorous and exothermic and can destroy containers if water is added directly (Nicholson, D.G. et al. Inorg. Synth. 3, 35 1950). Experimental work at Argonne National Laboratory has determined that the expected production of HBr gas by hydrolysis of AlBr3 is actually quite slow; no gas was produced within the first 20 minutes of the experiment. This finding does not preclude the possibility of formation of HBr by a catalytic mechanism, but HBr production by direct hydrolysis was not observed in this experiment. However, formation of a hydrated AlBr3 complex was observed and it was a rapid and exothermic process. The heat evolved in this reaction could result in the production of acidic mists if a large quantity of aluminum bromide is spilled into a small quantity of water (Brown, D. F., et al. (2000) Development of the Table of Initial Isolation and Protective Action Distances for the 2000 Emergency Response Guidebook, ANL/DIS-00-1, Argonne National Laboratory, Argonne IL).

ALUMINUM CHLORIDE fumes in moist air and undergoes a vigorous reaction with water (Anon., Ind. Eng. Chem. (News Ed.), 1934, 12, 194). Experimental work at Argonne National Laboratory has determined that the expected production of HCl gas by hydrolysis of AlCl3 is actually quite slow; no gas was produced within the first 20 minutes of the experiment. This finding does not preclude the possibility of formation of HCl by a catalytic mechanism, but HCl production by direct hydrolysis was not observed in this experiment. However, formation of a hydrated AlCl3 complex was observed and it was a rapid and exothermic process. The heat evolved in this reaction could result in the production of acidic mists if a large quantity of aluminum chloride is spilled into a small quantity of water (Brown, D. F., et al. (2000) Development of the Table of Initial Isolation and Protective Action Distances for the 2000 Emergency Response Guidebook, ANL/DIS-00-1, Argonne National Laboratory, Argonne IL).

ANTIMONY PENTACHLORIDE, LIQUID fumes in air to form hydrochloric acid. The compound reacts with water to yield heat and antimony pentaoxide (Sb2O5) and hydrochloric acid (The Merck Index, Rahway (NJ), Merck and Co. Inc., 11th ed. 1989).

ANTIMONY TRICHLORIDE fumes in air to form hydrochloric acid (The Merck Index, Rahway (NJ), Merck and Co. Inc., 11th ed. 1989). The compound is decomposed by water to form hydrochloric acid and antimony oxychloride. The dry powdered oxide ignites on heating in air (Mellor, J.W. 1939. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 9, p. 425. Longmans, Green and Co Ltd.).

ARSENIC IODIDE, SOLID reacts slowly with oxygen from the air, liberating iodine. It is water soluble. Aqueous solutions are strongly acidic (pH of 0.1N solution about 1.1) and ultimately form HI and As2O3, although an equilibrium AsI3 + 3H2O = H3AsO3 + 3HI has been observed (The Merck Index, Rahway (NJ), Merck and Co. Inc., 11th ed. 1989).

BERYLLIUM CHLORIDE reacts with water with evolution of heat. The compound forms beryllium oxide and hydrochloric acid solution. It corrodes most metals in presence of moisture. Flammable and explosive hydrogen gas may collect in enclosed spaces (U.S. Coast Guard. 1999. Chemical Hazard Response Information System (CHRIS) - Hazardous Chemical Data. Commandant Instruction 16465.12C. Washington, D.C.: U.S. Government Printing Office. Available online at http://www.uscg.mil/directives/cim/16000-16999/CIM_16465_12C.pdf)

STANNIC CHLORIDE, ANHYDROUS fumes in moist air. The compound reacts with water to form hydrochloric acid in dense white fumes (The Merck Index, Rahway (NJ), Merck and Co. Inc., 11th ed. 1989).

TITANIUM TETRACHLORIDE reacts exothermically with moisture in the air to evolve dense white fumes containing hydrochloric acid (The Merck Index, Rahway (NJ), Merck and Co. Inc., 13th ed. 1996). Titanium tetrachloride reacts vigorously with water to generate gaseous HCl. In experiments at Argonne National Laboratory, in which it was mixed with water and stirred at room conditions, about 27 percent of the theoretical yield of HCl evolved as a gas within the first 5 minutes (Brown, D. F., et al. (2000) Development of the Table of Initial Isolation and Protective Action Distances for the 2000 Emergency Response Guidebook, ANL/DIS-00-1, Argonne National Laboratory, Argonne IL).

TITANIUM TRICHLORIDE is pyrophoric; it reacts vigorously with water or moisture in air to produce hydrochloric acid (The Merck Index, Rahway (NJ), Merck and Co. Inc., 11th ed. 1989). The compound ignites spontaneously on contact with air; it is decomposed by water and water vapor, forming HCl (Handling 365betÓéÀÖ Safely, Dutch Association of Safety Experts, Dutch Chemical Industry Association, Dutch Safety Institute, 1980, p. 905).

VANADIUM TETRACHLORIDE forms acid mists in moist air. The compound reacts with water to form corrosive fumes of HCl (Handling 365betÓéÀÖ Safely, Dutch Association of Safety Experts, Dutch Chemical Industry Association, Dutch Safety Institute, 1980, p. 952).

Boron tribromide fumes in air, evolving hydrobromic acid. It can react vigorously or explosively with water to generate heat and acidic HBr vapors (Mellor, J.W. 1946. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 5, p. 124. Longmans, Green and Co Ltd.). In experiments at Argonne National Laboratory, in which it was mixed with water and stirred at room conditions, nearly 100 percent of the theoretical yield of HBr evolved as a gas in the first 0.4 minutes (Brown, D. F., et al. (2005) Development of the Table of Initial Isolation and Protective Action Distances for the 2004 Emergency Response Guidebook, ANL/DIS-05-2, Argonne National Laboratory, Argonne IL).

Boron trichloride fumes on contact with water, including moisture in air and soil, to form hydrochloric acid. Reacts vigorously with water and forms hydrochloric acid fumes and boric acid (The Merck Index, Rahway (NJ), Merck and Co. Inc., 11th ed. 1989).

Phosphorus trioxide fumes in air. It reacts slowly with cold water to give phosphorous acid. The acid reacts vigorously with hot water to generate red phosphorus, phosphine gas, and phosphoric acid (Mellor, J.W. 1940. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 8, p. 897. Longmans, Green and Co Ltd.).
