Isoprene separation technology

Thread Content

I would like to ask about the technologies used for the separation of isoprene in the following companies: 1. Shandong Yuhuang Chemical Industry, 2. Luhua Chemical Industry, 3. Puyang Xinyu Petrochemical Co., Ltd. Could you provide detailed information on this?

Industrially, thermal dimerization is generally used to separate cyclopentadiene, after which solvent extraction distillation or azeotropic distillation is employed to separate isoprene

DMF extraction distillation is used quite often, I think.

Luhua’s C5 separation is via DMF extraction
