Itaconic acid 1. Properties Itaconic acid or methylene succinic acid MW: 130.1; MF: C5H6O4; Structural Formula: 2. Specification Appearance white crystal or powder Purity 99.7%min Melting point 165-168 °C Loss on drying 0.1% max Ignition residue 0.1% max Color 5 APHA max Iron(Fe) 5 ppm max Heavy metal 5 ppm max Chloride 5 ppm max Sulfate 20 ppm max Cu: 1 ppm max Mn:: 1 ppm max 3. Packing 1)25kg in woven bag inner-lined with plastic bag. 2)Upon customer's request.(such as 1000kgs or 500kgs bag) 4.UsageUsage of itaconic acid (CAS No.: 97-65-4): 1) As cross-linking agent: The copolymerization of itaconic acid and vinyl can produce polystyrene resin which has such advantages as light in weight, waterproof, anticorrosion and good plasticity. Filling in glass fiber, it can be produced as high-strength glass steel. It can also be coated with paper and the back side of carper.2) As intermediate of synthetic fiber: Acrylic fiber with itaconic acid as the third monomer has such advantages of good feeling and easy dyeing.3) As binding material: The acrylic emulsion of containing itaconic acid is excellent binder of non-weaving fiber. The monomeric PVC binder of containing itaconic acid is good binder of paper and celluloid.4) Applied to produce detergents: The copolymer of itaconic acid and acrylic acid is a polymolecular chelating agent which acts as detergent for boller and water-cool system preventing formation of basic calcium and magnesium filth.5) Producing adhesives: The acrylic acid emulsion made from itaconic acid is a better adhesive for non-woven fibers. PVC adhesives contains itaconic acid monomer has strong adhesive property to paper and celluloid.6) Producing dental sticker (adhesive): The cross linkage of itaconic acid acrylic acid and polyvalent metal oxide can be synthesized to dental stocker which has good pressure resistance and phystolotgic adaptability. Moreover, we can synthesize pyrrolldone derivative by itaconic acid and amine, which is one composition of lubricant, detergent, medicine and herbicide. Itaconic acid is a good additive to synthetic resin, ion-exchange resin and surface active agent, a good plasticizer in plastics, materials of mesaconic acid and its anhydrinde, citraconic acid and its anhydride.7) Production of carbon fiber 8) Production of styrene-butadiene latex carboxylated 9) Production of unsaturated polyester resin and ion exchange resin 10) Production of textile reagent and organic chemical reagent 11) Watermark printing and production of gluing agent, detergent, weed killer, anti-scaling agent for boilers and coolers and anti-scale agent for seawater flash off boilers 12) A mixture of itaconic acid features excellent shock reduction and extensibility and can be used in automobile shock reduction and extensibility and can be used in automobile shock absorbers 13) Production of polymers of acrylic acid emulsion, adhesives, lubrication liquids for drills, thickening agents and fiber dyeing agents 14) Production of quality coating or backing for carpet or paper, as it forms stable emulsions15) Cementing agent: The plastics and coating which are produced by using itaconic acid of 1 - 5% and styrene to coplymize possess the advantages of lightweight, easy to paint, isolation, waterproof and anti-corrosion; can be used to make glass fiber reinforced plastic of high strength or as coat of carpet and the face of paper.16) Used to process transparent materials: The polymer of itaconic acid has special luster and transparency, suitable for making artificial gems (diamonds) and special purpose lens. 5.Storage and transportation Keep away from moisture, sunlight, and rain.
