Isoprene is a valuable monomer for the rubber and most chemical industries.
Isoprene (C5H8) is a colourless liquid with an aromatic odour. It is insoluble in water, soluble in alcohol and because of its low vapour pressure and double bonds is very reactive
Isoprene is classified as a possible human carcinogen by the International Agency for Research on Cancer
Isoprene Feedstock is mainly used to produce isoprene and piperylene
Some of the methods for isoprene synthesis used on an industrial scale are
1. Synthesis from Isobutylene and formaldehyde.
2. Dehydration of isopentane.
3. Oxidative dehydration of isopentane.
4. Synthesis from propylene.
5. Synthesis from acetylene and acetone.
6. Recovery of isoprene from C5 fraction of liquid petroleum pyrolysis.
7. Liquid phase oxidation of hydrocarbons.
The rapid development of synthetic
rubber is a result of the huge demand for this material.
Isoprene prices in both, China and US have witnessed a downtrend since the beginning of the year 2013.
The polymerisation of isoprene using catalysts yields a synthetic rubber, polyisoprene, which closely resembles natural rubber. Polyisoprene is used in a wide variety of rubber applications
including medical equipment, baby bottle teats/nipples, toys, shoe soles, tyres, and elastic films and threads for golf balls or textiles. It is also used in adhesives and in paints and coatings
Isoprene is an important chemical with annual demand of over a million tons per year
