Itaconic酸

Features (itaconic acid): 1) Properties:a) Itaconic acid or methylene succinic acidb) M.W.: 130.1c) M.F.: C5H6O4 2) Applications:a) Itaconic acid and its polymers can be made into effective deodorant by adding a little natural substance, to react with alkaline or acidic odor, including ammonium, amine, and hydrogen sulfide. This acid can also be used in paper and plastic thin film with deodorant functionsb) Itaconic acid can copolymerize with styrene and butadiene to prepare SBR latex, which is widely used for paper coatings, metal and concrete paint; it is used for paints to improve quality and used as fiber carpet sizing agent to make carpet more ndurablec) Itaconic acid can react with acrylic and methacrylic acid or esters to prepare for resins, which can be widely used for emulsion coating,leather coating and coatings for car, refrigerator and other electrical appliances to improve adhesion, color and weather resistance. This acid can also be used for electro-coating with excellent adhesion, in dental binder with the helpof metal oxides. With chloroalkyl dimethylbenzylammonium chloride added, it can be used for preparing for water soluble coating for food packaging to reduce bacteria contaminationd) Esters of itaconic acid can be used for paint, ion-exchange resin, lubricant, binder, plasticizer, sealant and plastics moldinge) Some other itaconic acid derivatives are used for medicine, cosmetics, lubricant, thickener, herbicide and wool modifier Specifications: 1) Appearance: white crystal or powder 2) Purity: 99.7% (min.) 3) Melting point: 165 - 168oC 4) Loss on drying: 0.1% (max.) 5) Ignition residue: 0.1% (max.) 6) Color: 5 APHA (max.) 7) Iron (Fe): 5ppm (max.) 8) Heavy metal: 5ppm (max.) 9) Chloride: 10ppm (max.) 10) Sulfate: 30ppm (max.)
