Solvents For Use In The Extractive Distillation Of Piperylene Concentrate, Abdulhadi Sagga

Retrospective Theses and Dissertations

This report describes an evaluation of the effectiveness of different solvents and solvent-organometallic compound mixtures for use in the extractive distillation of a piperylene mixture, consisting of five carbon olefins and diolefins obtained as a byproduct from an ethylene feedstock production plant. The most effective solvent is judged to be the one which gives the best separation of the lowest boiling and highest boiling points of the key components in the mixture. In this study twenty solvents and solvent mixtures were tested. Acetonitrile was found to be the most effective solvent and nitromethane the next most effective.
