디플루오로인산, 무수물 화학적 특성, 용도, 생산

화학적 성질
mobile, colorless liquid; fumes in air [KIR78]
일반 설명
A mobile colorless strongly fuming liquid. Density 1.583 g / cm3. Corrosive to glass, fabric, metals and tissue.
공기와 물의 반응
Fumes in air. Reacts vigorously with water to form corrosive and toxic hydrofluoric acid and heat.
반응 프로필
DIFLUOROPHOSPHORIC ACID reacts exothermically with chemical bases (examples: amines, amides, and inorganic hydroxides). These reactions can generate dangerously large amounts of heat in small spaces. Reacts vigorously with water to form corrosive and toxic hydrofluoric acid and heat. Reacts with active metals, including such structural metals as aluminum and iron, to release hydrogen, a flammable gas. Can initiate the polymerization of certain alkenes. Reacts with cyanide compounds to release gaseous hydrogen cyanide. Generates flammable and/or toxic gases in contact with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and strong reducing agents. Additional gas-generating reactions occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and carbonates. May catalyze (increase the rate of) chemical reactions.
건강위험
Inhalation causes severe irritation of upper respiratory tract. Contact with liquid causes severe irritation of eyes and skin. Ingestion causes severe burns of mouth and stomach.
화재위험
Special Hazards of Combustion Products: Irritating and toxic fumes of hydrogen fluoride and phosphoric acid may be formed in fires.
Safety Profile
Toxic and corrosive material. Very irritating to the skin, eyes, and mucous membranes. When heated to decomposition it emits very toxic fumes of POx and F-. Used as a catalyst. See also PHOSPHORODIFLUORIDIC ACID, anhydrous.
