STRONG ODOR OF HYDROGEN CHLORIDE

Fumes in moist air (forms a large amount of hydrogen chloride gas). Reacts with active metals in the presence of moisture to produce hydrogen and HCl gases. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Chloride gas will be created in 0.02 minutes.

Acids, Strong Non-oxidizing

Known Catalytic Activity

ALUMINUM CHLORIDE behaves as an acidic salt. Self-reactive. After long storage in closed containers, explosions often occur upon opening [Chem. Abst. 41:6723d 1947]. Can cause ethylene(also other alkenes) to polymerize violently [J. Inst. Pet. 33:254 1947]. Causes ethylene oxide to rearrange and polymerize, liberating heat [J. Soc. Chem. Ind. 68:179 1949]. Can catalyze violent polymerization of allyl chloride [Ventrone 1971]. Addition to nitrobenzene containing about 5% phenol caused a violent explosion [Chem. Eng. News 31:4915 1953]. Mixtures with nitromethane may explode when organic matter is present [Chem. Eng. News 26:2257 1948].|ALUMINUM CHLORIDE, SOLUTION is an aqueous solution of an acidic salt. Reacts exothermically with bases. May cause ethylene (also other alkenes) to polymerize violently [J. Inst. Pet. 33:254 1947].
