Production method

This is the product used in industry. The mixture of the product and its isomer, containing 76% of 2,4, 4-trimethyl-1- pentene, containing about 20% of 2,4, 4-trimethyl- 2-pentene[107-40-4], other octene accounts for 4%. Industrially from refineries or ethylene factory c4 fraction separated. The remaining part of butadiene after extraction from C4 fraction is used as raw material, and sulfuric acid is used. Selective absorption diisobutylene is then heated by sulfuric acid absorbing diisobutylene to separate and generate a polymer mainly composed of diisobutylene. After washing the polymer with sodium carbonate solution, the above industrial products are obtained by distillation and refining.
