Itaconic acid physicochemical characteristics: Itaconic acid is unsaturated diprotic acid.
Itaconic acid physicochemical characteristics:Itaconic acid is unsaturated diprotic acid. It has unsaturated double bond and active chemical properties. It is soluble in water, ethanol and other solvents. Being able to do various kinds of addition reactions, esterification reactions and polyreactions, it is important material for chemically synthetic industry as well as chemical production.Molecular weight: 130.1Specific gravity: 1.49Molecular formula: C5H6O4Quality certificate for itaconic acid Item: standardAppearance: white crystal or powder Purity: ≥99.6%Melting point: 165-168°CChroma: ≤5 APHAHeavy metal (pb) ≤1mg/kgIron (Fe): ≤1mg/kgSolubility, clarity (5% aqueous solution); clear, no turbidityAsh content: ≤0.01%Drying loss: ≤0.3%Sulphate (SO4): ≤20mg/kgChlorine (Cl): ≤10mg/kgUsage:1> The third monomer of acrylonitrile fiber; The acrylonitrile fiber, which takes itaconic acid as the third monomer, is easy to dye2> Adhesive: The plastic and coating with the application of 1%-5%itaconic acid and styrene complex have the features of light color, easy separation, waterproof and anticorrosion. It can be used in producing high intensity resin glass fiber. It is also used in carpet coating and book cover 3> Binding material: Acrylic acid emulsion with itaconic acid is excellent adhesive for non intertexture fiber products. Adhesive with itaconic acid, PVC monomer is also excellent adhesive for paper and celluloid4> Teeth adhesive: Teeth adhesive, made up of itaconic acid, acrylic acid and metal oxide, has excellent compression resistance and physiological adaptation5> Special lens: Polymer with itaconic acid has special luster and transparency. It is suitable to the production of artificial gem and special lens6> Detergent: Polymer of itaconic acid and acrylic acid is a kind of macromolecular chelating agent. It can be used in cleaning boilers and cooling equipment7> Itaconic acid and esters are excellent additive for producing synthetic resin, cation exchange resin and surface active agent8> Pyrrolidone derivatives produced on the mixture of itaconic acid and aromatic diamine are excellent additive for lubricant, cleaning agent, drugs and herbicide9> Itaconic acid is the material for producing citraconic acid and mesaconic acid Precautions:Please flush eyes and mouth with water in case of contactPacking, transportation:1. 25kg woven bag or compound brown paper bag with plastic lining2. 500kg or 1,000kg woven bag with plastic lining3.
