Itaconic acid is a white crystal or powder; Melting point is 165-168°C, Specific gravity is 1.632
Uses
1, If adding a small amount of natural materials, Taconic acid and its polymer can be made into high efficient deodorant, which can react with ammonia, amine alkaline, hydrogen sulfide and stench acid, also can be made into have paper, plastic film, with deodorization functions.
2, The copolymer of Itaconic acid , styrene and butadiene can be made into S.B.R emulsion, and can be used in paper coating; Used for metal, concrete coating, can make them easy to coloring and hard to be affected by natural conditions ; Used in paint additives, it can improve the quality of paint; Used for carpet sizing, it can make the carpet of synthetic fiber durable.
3, The polymers of Itaconic acid and acrylic acid or methyl acrylic or its esters can be used to produce resins, which can be used for surface coating and emulsion paint. As leather coating, it can increase the leather plasticity, Used in automobile, electric appliance, cold storage coating , it has strong adhesion, beautiful color and lustre and good resistance to bad climate etc; Used for electrophores is coating, it has excellent adhesion; If adding polyvalent metal oxide, it can be made into dental adhesive with good extrusion performance strong cohesive force and good physiological adaptability; Add chlorine alkyl dimethyl benzyl ammonium chloride, it can be made into water soluble paint, used in food Packing material, can reduce the bacterial contamination of Packing surfaces.
4, The esters of Itaconic acid can be used in paint, weak acidic ion exchange resin, additives of lubricating oil, binder and plasticizer, powder pressure plastic and seal adhesive.
5, Itaconic acid's derivatives can be used as medicine, cosmetics reagent, lubricant, thickener, herbicide and used to improve the performance of silk and wool fabrics.
6, Itaconic ester is material for the production of Citraconic acid, mesaconic acid and Itaconic anhydride, etc.
