Difasol utilities

Difasol An improvement on the Dimersol process for dimerizing propene or butenes. The process utilizes an ionic liquid based on imidazoliniumaluminate and a nickel-based Dimersol catalyst. Developed by IFP in 1999, but not commercialized by 2005. 

The Dimersol-Difasol arrangement ensures more efficient overall catalyst utilization and an increase in the yield of octenes by about 10 wt.% (Table 5.4-4). Table 5.4-5 shows a simplified mass balance comparison for the Dimersol process and... 

BASIL [Biphasic Acid Scavenging utilizing Ionic Liquids] A range of catalytic processes for synthetic organic chemistry. These processes use ionic liquids as solvents, from which it is easy to recover the catalysts. Developed by BASF from 2002 and first commercialized in 2004 for the synthesis of alkoxyphenyl phosphines. Awarded the Entec Medal for safety and environmental innovation in 2005. See also Difasol.
