Maleic acid Chemical Properties,Usage,Production

Chemical Properties White solid General Description Maleic acid is a colorless crystalline solid having a faint odor. Maleic acid is combustible though Maleic acid may take some effort to ignite. Maleic acid is soluble in water. Maleic acid is used to make other chemicals and for dyeing and finishing naturally occurring fibers. Air & Water Reactions Soluble in water. Reactivity Profile Maleic acid is a colorless to white crystalline solid. Moderately toxic. When heated to decomposition Maleic acid emits irritating fumes and acrid smoke [Lewis, 3rd ed., 1993, p. 790]. Health Hazard Inhalation causes irritation of nose and throat. Contact with eyes or skin causes irritation. Fire Hazard Special Hazards of Combustion Products: Irritating smoke containing maleic anhydride may form in fire.
