i�cNvi L i uta vi r Strong Oxidizing Agent Known Catalytic Activity Water-Reactive Air &Water Reactions Reaction with water is negligible unless acid strength is above 80-90% then heat from hydrolysis is extreme, may cause severe burns [Merck, 11th ed. 19891.During sulfonation of mononitrobenzene by fuming sulfuric acid, a leak from an internal cooling coil permitted water to enter the reaction tank.A violent eruption occurred due to the heat of solution[MCA Case History 944 19631. Fire hazard It is highly reactive and capable of igniting finely-divided combustible materials on contact.When heated, it emits highly toxic fumes. Avoid heat;water and organic materials.Sulfuric acid is explosive or incompatible with an enormous array of substances. Can undergo violent chemical change at elevated temperatures and pressure.May react violently with water.When heated, it emits highly toxic fumes.Hazardous polymerization may not occur. (EPA, 1998) Health Hazard Corrosive to all body tissues. Inhalation of vapor may cause serious lung damage. Contact with eyes may result in total loss of vision. Skin contact may produce severe necrosis.Fatal amount for adult:between 1 teaspoonful and one-half ounce of the concentrated chemical. Even a few drops may be fatal if the acid gains access to the trachea. Chronic exposure may cause tracheobronchitis, stomatitis, conjunctivitis, and gastritis. Gastric perforation and peritonitis may occur and may be followed by circulatory collapse. Circulatory shock is often the immediate cause of death.Those with chronic respiratory, gastrointestinal, or nervous diseases and any eye and skin diseases are at greater risk. (EPA, 1998) Reactivity Profile SULFURIC ACID is strongly acidic.Reacts violently with bromine pentafluoride [Mellor 2 Supp. 1:1'72 1956]. Exploded with para-nitrotoluene at 80°C [Chem.Eng.News 27:2504]. An explosion occurred when concentrated sulfuric acid was mixed with crystalline potassium permanganate in a vessel containing moisture. Manganese heptoxide was formed,which explodes at 70°C [Delhez 1967].A mixture of acrylonitrile with concentrated sulfuric acid must be kept well chilled,otherwise a vigorous exothermic reaction occurs [Chem. Safety Data Sheet SD-31:8. 1949].Mixing sulfuric acid(96%)in equal portions with any of the following substances in a closed container caused the temperature and pressure to increase: acetonitrile, acrolein, 2- aminoethanol,ammonium hydroxide(28%), aniline,n-butyraldehyde,chlorosulfonic acid, ethylenediamine, ethyleneimine,epichlorohydrin, ethylene cyanohydrin,hydrochloric acid(36%),hydrofluoric acid(48.7%),, propiolactone,propylene oxide, sodium hydroxide, styrene monomer[NFPA 1991]. Sulfuric acid (concentrated) is extremely hazardous in contact with carbides,bromates,chlorates, fulminates,picrates,and powdered metals [Haz. Chem.Data 1966].Allyl chloride may polymerize violently under conditions involving an acid catalyst, such as sulfuric acid [Ventrone 1971].React exothermically with sodium hypochlorite to produce chlorine gas. Mixing chlorosulfuric acid and 98% sulfuric acid may evolve HCl [Subref: Anon,Loss Prev.Bull. 1977, (013),2-3].Zinc iodide reacts violently with H2SO4. (Pascal, 1962,Vol. 5, 168). Belongs to the Following Reactive Group(s) Acids;Strong Oxidizing Potentially Incompatible Absorbents Use caution:Liquids with this reactive group classification have been known to react with the absorbents listed http://l27.0.0.1:54673/report?key=CH5193 4/15/2015
