nature
Colorless orthogonal acicular crystal or white crystalline powder. Soluble in water, acetone, benzene, chloroform and other organic solvents. Solubility (gllOOg) at 25ºC in the following solvents: acetone 227, ethyl acetate 112, chloroform 52.5 I benzene 50 I toluene 23.4; O-xylene 19.4; Carbon tetrachloride 0.60; Petroleum ether 0.25. Dissolve in alcohol to form esters. Dissolved in dioxane. Sublimation by heat. Risk of burning in high heat, open flame or contact with oxidants. It's corrosive. It is slowly hydrolyzed in cold water to produce maleic acid. Contact with strong oxidants can cause combustion and explosion. If the temperature exceeds 66ºC, the polymerization reaction will occur in contact with amines or alkali metals.
preparation
Malic acid reacts with acetyl chloride at a certain temperature, after the reaction is completed, it is distilled, and then recrystallized with trichloromethane to obtain pure maleic anhydride.
use
Reagent for the determination of organic compounds with conjugated double bonds. Also used in synthetic resins, coatings, pesticides, medicine, food, and lubricating oil additives.
