| Itaconic acid Usage And Synthesis |
| Chemical Properties | white to light beige crystalline powder | | Uses | Copolymerizations, resins, plasticizers, lube-oil
additive, intermediate. | | Uses | The major uses for itaconic acid are in copolymerizations,
resins, plasticizers, and as lube oil additives. | | Uses | Itaconic acid is used in the preparation of acrylonitrile-butadiene-styrene and acrylate latexes. It is also used to prepare poly-itaconic acid, resins biofuel components and ionomer cements. It finds application in the textile, chemical and pharmaceutical industries. It is also used as an additive in fibers and ion exchange resins to increase abrasion, waterproofing, physical resistance, dying affinity and better duration. Further, it acts as a co-monomer used in the preparation of acrylic fibers and rubbers, reinforced glass fiber, artificial diamonds and lens. In addition to this, it acts as a binder and sizing agent in non-weaving fibers. | | Definition | itaconic acid: A product of the fermentationof the flamentous fungusAspergillus niger. Itaconic acid is usedcommercially in the production ofadhesives and paints. | | Definition | ChEBI: A dicarboxylic acid that is methacrylic acid in which one of the methyl hydrogens is substituted by a carboxylic acid group. | | General Description | Itaconic acid, an unsaturated dicarbonic organic acid, is a metabolic product of Aspergillus itaconicus. | | Flammability and Explosibility | Nonflammable | | Purification Methods | Crystallise itaconic acid from EtOH, EtOH/water or EtOH/*benzene.
