Dissociation Constants:The dissociation constants pK1 and pK2 for terephthalic acid at 25 °C are 3.54 and 4.46, respectively.
Experimental Properties:Sublimes at 402 °C|Hydroxyl radical reaction rate constant = 1.2X10-12 cu cm/molec-sec at 25 °C (est)
Air and Water Reactions:Insoluble in water.
Reactive Group:Acids, Carboxylic
Reactivity Profile:TEREPHTHALIC ACID is a carboxylic acid. It donates hydrogen ions if a base is present to accept them. This "neutralization" generates substantial amounts of heat and produces water plus a salt. Insoluble in water but even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in it to corrode or dissolve iron, steel, and aluminum parts and containers. May react with cyanide salts to generate gaseous hydrogen cyanide. Will react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. Flammable and/or toxic gases and heat are generated by reaction with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. React with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. Can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. May initiate polymerization reactions; may catalyze (increase the rate of) chemical reactions.
Autoignition Temperature:925 °F (496 °C)|496 °C
Physical Dangers:Dust explosion possible if in powder or granular form, mixed with air.
