11 Toward Industrialization of Ionic Liquids

15. There is a growing number of successful implementations in industry today, but
most are not visible to the public.
16. Ionic liquids are too difficult in handling, operation, and recycling.
17. Ionic liquids have the potential to revolutionize the world.
Figure 11.5 summarizes the results of the survey. Though more than 60% of the
survey participants agreed that ionic liquids “meet the technical requirements of
the industry” (statement 1), only 26% of participants totally or mostly agree with
this statement. Industry has not yet fully defined appropriate technical specifications
and standards (e.g., purity, electrochemical stability, rheology, and corrosion) to
implement ionic liquids [48]. During discussions regarding technical requirements,
several participants stated that the overall quality of commercial ionic liquids has
increased over the years, but individual batch quality remains a fluctuating problem.
Some participants believe that today’s ionic liquids are kind of “old fashioned,” and
new structures are needed.
