Itaconic Acid Description: Physicochemical
characteristics:
Itaconic acid is unsaturated diprotic acid. It has unsaturated double bond
and active chemical properties. It is insoluble 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.

Use:
1 >The third monomer of acrylonitrile fibre ; The acrylonitrile
fibre, which takes itaconic acid as the third monomer, is easy to dye.
2 > 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 fibre. 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 fibre products. Adhesive
with itaconic acid, PVC monomer is also excellent adhesive for paper and
celluloid.
4 > Teeth adhesive: Teeth adhesive, made up of itaconic
acid, acrylic acid and metal oxide, has excellent compression resistance
and physiological adaption.
5 > Special lens: Polymer with itaconic acid has special
luster and transparency. It is suitable to the production of artificial
gem and special lens.
6 > Detergent: Polymer of itaconic acid and acrylic
acid is a kind of macromolecular chelating agent. It can be used in cleaning
boilers and cooling equipment.
7 > Itaconic acid and esters are excellent additive
for producing synthetic resin, cation exchange resin and surface active
agent.
8 > Pyrrolidone derivatives produced on the mixture
of itaconic acid and aromatic diamine are excellent additive for lubricant,
cleaning agent, drugs and herbicide.
9 > Itaconic acid is the material for producing citraconic
acid and mesaconic acid etc..
Precautions
Please flush eyes and mouth with water in case of contact.
