Descripción del producto

​Itaconic acid is a white crystal or powder; The melting point is ******8 ℃, the specific gravity is 1.**2, and it is soluble in water, ethanol, and other solvents. Itaconic acid has active chemical properties and can carry out various addition reaction, esterification reactions and polymerization reactions.

​1. Itaconic acid and its polymers can be made into high-efficiency deodorants by adding a small amount of natural substances, which can react with acidic odors such as ammonia, amine alkaline odors, and hydrogen sulfide. They can also be made into a series of products such as paper and plastic films with deodorization functions.
2. The copolymerization of itaconic acid with styrene and butadiene can produce S.B.R latex, which can be used for paper coating, making the paper strong and durable, and printing patterns bright; Used for metal and concrete coatings, easy to stain and unaffected by natural conditions; Used as a paint additive to improve paint quality; Used for carpet sizing to make synthetic fiber carpets durable and durable.
3. Itaconic acid is polymerized with acrylic acid, methacrylic acid, or its esters to form a resin, which can be used for surface coatings and emulsion paints. As a leather coating, it can increase the plasticity of leather; Used as a coating for automobiles, electrical appliances, and cold storage, it has advantages such as strong adhesion, beautiful color, and resistance to harsh weather conditions; Used as an electrophoretic coating with excellent adhesion; Adding multivalent metal oxides can make dental adhesives with good extrusion performance, strong adhesion, and good physiological adaptability; Adding chloroalkyl dimethyl benzyl ammonium chloride can make water-soluble coatings, which can be used as food packaging materials to reduce bacterial contamination on the surface of packaging materials.
4. Itaconic acid esters can be used in paints, weakly acidic ion exchange resins, lubricating oil additives, adhesives and plasticizers, powder pressed plastics, and sealants.
5. Other derivatives of itaconic acid can be used as pharmaceuticals, cosmetic reagents, lubricants, thickeners, herbicides, and to improve the properties of silk and wool fabrics.
6. Itaconic acid ester is a raw material for the production of citric acid, citric acid, itaconic anhydride, etc.
