WERKWIJZE VOOR HET CONTINU HYDROGENEREN VAN CYCLOPENTADIEEN.

摘要

There is disclosed a process for the preparation of cyclopentene from cyclopentadiene which comprises selectively hydrogenating cyclopentadiene in the liquid phase by continuously contacting cyclopentadiene with hydrogen while passing the mixture of hydrogen and cyclopentadiene through a highly dispersed form of nickel catalyst which nickel has been treated with ammonia.
