Air and Water Reactions:Water soluble.
Reactive Group:Acids, Strong Oxidizing
Reactivity Alerts:Strong Oxidizing Agent
Reactivity Profile:TOLUENE SULFONIC ACID, LIQUID, WITH MORE THAN 5% FREE SULFURIC ACID reacts exothermically with chemical bases (for example: amine, amides, and inorganic hydroxides). The reactions can generate dangerously large amounts of heat in small spaces. Dissolution in water or dilution of concentrated solutions with water may generate significant heat. Reacts with sodium hypochlorite to produce chlorine gas. Can react with active metals, including iron and aluminum, and also many less active metals, to dissolve the metal and liberate hydrogen and/or toxic gases. Can initiate possibly violent polymerization in certain alkenes such as allyl chloride. Reacts with cyanide salts and compounds to release gaseous hydrogen cyanide. Flammable and/or toxic gases are also often generated by reactions with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and weak or strong reducing agents. Additional gas-generating reactions may occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and carbonates: the carbon dioxide gas from the last is nontoxic but the heat and spattering from the reaction can be troublesome. Can catalyze (increase the rate of) chemical reactions. May burn but not ignited readily. Incompatible with carbides, bromates, chlorates, fulminates, picrates, and powdered metals [Haz. Chem. Data 1966]. Produces highly toxic fumes of oxides of sulfur when heated to decomposition.
