107-39-1 - Uses and synthesis methods
application
2,4, 4-trimethyl-1-pentene can be used as surfactant, phenolic resin and epoxy resin modifier, synthetic rubber tackifier, ultraviolet absorber, PVC heat stabilizer, Plasticizer, etc., is a fine chemical raw material widely used in various fields. It can also be used as an intermediate in organic synthesis such as octylphenol and nonylphenol, and its role is becoming more and more important.
production method
The product used in industry is a mixture of the product and its isomers, containing the 76% of the product, containing about 20% 2,4, 4-trimethyl-2-pentene [107-40-4], Other octenes account for 4%. Industrially obtained from the carbon four fraction of a refinery or ethylene plant. The remaining part of butadiene extracted from the C4 fraction is used as raw material, and sulfuric acid is used to selectively absorb diisobutylene, and then the sulfuric acid that has absorbed diisobutylene is heated to separate and form a polymer based on diisobutylene. After washing the polymer with sodium carbonate solution, it is refined by distillation to obtain the above industrial products.
