Isoprene CAS 78-79-5
Sinochem is a major Isoprene supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China Isoprene.
An important organic chemical raw material, colorless volatile liquid at room temperature and pressure, with pungent odor. Slightly soluble in water, can be miscible in ethanol, ether, acetone and other organic solvents. Polymerization is easy to occur, oxidation and polymerization are easy to occur in the storage process, often add a small amount of stabilizers such as hydroquinone, etc., mainly used to make styrene butadiene rubber and cis-polyisoprene rubber.
- Highly reactive
- Used as a chemical raw material in organic synthesis
- Rubber modifier
- Solvent for coatings and adhesives
Isoprene Description
NAME: Isoprene

Flashing point: -48 ºC
Appearance: The colorless liquid has an aromatic smell.
Solubility: Insoluble in water, soluble in ethanol, ether and other organic solvents.
Properties: Colorless, volatile, irritating oily liquid. Insoluble in water, soluble in benzene, easily soluble in ethanol, ether, and acetone. Forms explosive mixture with air.
Storage: Maintain storage in a cool and well-ventilated facility, ensuring that the ambient temperature remains below 29℃. It is essential to keep the material away from any sources of ignition and heat. The packaging must be sealed and kept free from air exposure. Additionally, it is crucial to store the material apart from oxidizing agents, acids, halogens, and similar substances to prevent any potential reactions. Large quantities should not be stored, and long-term storage is discouraged. Utilize explosion-proof lighting and adequate ventilation systems. Avoid using mechanical devices and tools that could generate sparks. Moreover, the storage area must be equipped with emergency leak response materials and appropriate containment solutions.
Safety Protection: High concentrations of vapor have an anesthetic effect and can damage internal organs if taken orally. The maximum allowable concentration in the air is 0.04 mg/L. The workplace should be well ventilated and operators should wear masks. Vapors and liquids can irritate the eyes, skin and respiratory system.

Isopentadiene Applications
1. It is primarily utilized in the production of synthetic isoprene rubber, with its output trailing only behind styrene-butadiene rubber and butadiene rubber, thereby securing the position of the third most prevalent synthetic rubber.
2. It serves as a copolymer with synthetic butyl rubber to enhance the vulcanization characteristics of butyl rubber, albeit in minor quantities, of isoprene.
2. It finds applications in the synthesis of synthetic resin and liquid polyisoprene rubber, among others.
3. Its uses also extend to the production of pesticides, pharmaceuticals, flavoring agents, and adhesives.
