Chemical hazards with strong acids

ACRYLIC ACID, 2-ETHYLHEXYL-ESTER (103-11-7) CnHjoOj Combustible liquid. Forms explosive mixture with air [explosion limits in air (vol %) 0.8 to 6.4 flashpoint 180°F/82°C oc autoignition temp 496°F/258°C Fire Rating 2]. Unless inhibited, contact with heat, sunlight, contaminants, or peroxides may cause hazardous polymerization. Reacts violently ivith strong oxidizers, with risk of fire and explosions. Incompatible with strong acids, alkalis, aliphatic amines, alkanolamines, nitrates. The uninhibited monomer vapor may block vents and confined spaces by, forming a solid polymer material. On small fires, use AFFF, foam, dry chemical, or COj extinguishers. 

HAZARD RISK Non-combustible solid moderate fire hazard in the form of powder moderate fire hazard when exposed to flame or by spontaneous chemical reaction incompatible with halocarbons reacts incandescently with fluorine or chlorine decomposition emits toxic fumes of beryllium oxide reacts with strong acids and strong bases forming combustible gas forms shock sensitive mixtures with some chlorinated solvents including carbon tetrachloride and trichloroethylene NFPA code H3 FI RO. 

CHEMICAL PROPERTIES stable under ordinary condition of use and storage hazardous polymerization will not occur reacts with strong acids, oxidizing materials, chlorine, hypochlorite, halogenated compounds, and reactive organic compounds liberates ammonia vapor upon decomposition FP (-12°C, 10°F) LFLAJFL (1.7%, 9.8%) AT (312°C, 594°F) HF (-127.7 kJ/mol liquid at 25°C). 

CHEMICAL PROPERTIES generally very stable hazardous polymerization will not occur reacts vigorously with strong acids and strong oxidizers FP (NA) LFL/UFL (NA) AT (NA) HF (NA) HC (NA). 

EXPLOSION and FIRE CONCERNS combustible liquid and vapor NFPA rating Health 1, Flammability 2, Reactivity 0 explosive vapor-air mixtures may be formed above 48°C (118°F) flashback along vapor trail may occur closed containers may explode when heated sensitive to static discharge contact with strong oxidizers may cause fire may form explosive peroxides attacks some forms of plastics incompatible with strong acids, alkalies, and oxidizers hazardous decomposition products include carbon monoxide and carbon dioxide use alcohol-resistant foam, dry chemical or carbon dioxide for firefighting purposes. 

CHEMICAL PROPERTIES stable in cold in absence of air sensitive to light dark color does not affect purity air sensitive oxidizes in presence of air reduces warm ammonia-cal silver nitrate hazardous polymerization will not occur incompatible with strong acids and strong oxidizing agents FP (157 C, 315°F) LFL/UFL (data not available) AT (data not available). 

CHEMICAL PROPERTIES corrosive low ignition energy polymerizes exothermically hazardous polymerization may occur due to high temperatures or contamination with highly active catalysts, aqueous acids, bases, amines, and acidic alcohols reacts with strong acids, alkalies, salts, clay based absorbents, and combustible materials reaction with water may lead to a runaway reaction FP (-37°C, -35°F) LFL/UFL (2.3%, 36.0%) AT (465°C, 869°F) HC (-13,000 Btu/lb, -7221 cal/g, -302.3 x lO J/kg) HF (-122.6 kJ/mol liquid at 25°C).
