An organic compound which is discarboxylic acid also regarded with a molecule with two carboxyl groups is known as maleic acid. Maleic acid is mainly used as a precursor to fumaric acid and is very much to its parent maleic anhydride as it has few applications. Maleic acid is considered to be less stable than that of formic acid as because it is more soluble in water than that of fumaric acid. Maleic acid is majorly used for converting it into formic which is considered as industrial application or industrial use and also is an industrial raw material for the production of glyoxylic acid by ozonolysis.
Maleic acid is commercially available in crystalline material or as an aqueous solution in water as it may contain fumaric acid and water in the form of impurities. Maleic acid is mainly used for making maleate salts of bulk drugs which are used for preventing rancidity of oils. Maleic acid is employed in the manufacture of phthalic type of alkyd and polyester resins, surface coatings, copolymers, plasticizers, lubricant addictives and agricultural chemicals like adhesives and sealants. Maleic acid is made of hydrogen, oxygen and carbon and also is known as toxilic and malenic acid. Maleic acid must be stored in ventilated area which is very much grounded as flammable can cause a flash fire or explosion in case if electrostatic charge is emitted.
Effects of inhaling of maleic acid could even lead damage to the upper respiratory tract, causing sneezing, coughing and can also cause irritation in eyes enabling the eyes to become red and thus the eyes would pain. Maleic acid is soluble in acetone, alcohol and is considered to be an unsaturated organic dibasic acid. Maleic acid is widely used for the production of fumaric acid and also other chemicals which are carboxylating agents. Today maleic acid has become a new acidulent in food and beverage industry as it enhances the fruit aroma and improves the taste of food and beverage with which is used in syrups, orange juice.
