Description

Maleic Anhydride

maleic anhydride , often referred to as maleic anhydride. Colorless crystal, strong irritating odor, freezing point 52.8℃, boiling point 202℃, easy to sublimate. It is mainly produced by the oxidation of n-butane or butene in benzene or C-4 fraction. It is the raw material for the production of unsaturated polyester and organic synthesis.

Colorless orthogonal acicular crystal or white crystalline powder. Soluble in water, acetone, benzene, chloroform and other most organic solvents. Solubility (gllOOg) at 25℃ 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 ignition in contact with high heat, open flame or oxidant. It is corrosive. It hydrolyzes slowly in cold water to produce maleic acid. Contact with strong oxidants can cause combustion and explosion. If the temperature exceeds 66℃, contact with amines or alkali metals will occur polymerization reaction.

Reagent for the determination of organic compounds with conjugated double bonds. Also used in synthetic resins, coatings, pesticides, medicine, food, and lubricating oil additives.
