cis-1,2,3,6-tetrahydrophthalic anhydride; >98% usage and synthesis
general description clear colorless to light yellow slight viscous liquid. highly toxic and a strong irritant to skin, eyes and mucous membranes. corrosive to skin and metal. used in making polyester, alkyd resins, and plasticizers.
air & water reactions reacts exothermically with water to form memtetrahydrophthalic acid.
reactivity profile cis-1,2,3,6-tetrahydrophthalic anhydride; >98% is combustible. reacts with oxidizers. reacts exothermically with water. these reactions are usually slow, but can become violent when local heating accelerates their rate. acids accelerate the reaction with water. incompatible with acids, strong oxidizing agents, alcohols, amines, and bases.
health hazard toxic; inhalation, ingestion or skin contact with material may cause severe injury or death. contact with molten substance may cause severe burns to skin and eyes. avoid any skin contact. effects of contact or inhalation may be delayed. fire may produce irritating, corrosive and/or toxic gases. runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
fire hazard non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). contact with metals may evolve flammable hydrogen gas. containers may explode when heated.
