Ionic Liquids

06/17/2009 2:54 PM

Ionic liquids are room temperature fluids composed entirely of ions,

typically large organic cations and small inorganic anions.

Ionic liquids have no detectable vapor pressure and do not emit volatile organic

compounds (VOCs), providing a basis for clean manufacturing – "green chemistry."

Some physical properties like wide electrochemical window, solubility, make them interesting as potential solvents in many chemical synthesis in organic and inorganic material.

At the last few years Ionic Liquids have been applied in application area such: Engineering:

Membran Technology, Extraction, Gas Separation, Rectification

Material process:

Metal Plating, Surfactant, Lubricant, Antistatics, Dispergents

Electrochemistry:

Photopholtaic Cell, OLED, Electrchromating, Phosphating

Mass Chemistry:

Pulping Process, Cellulose, PetroChemistry, Biomass conversion

FineChemistry:

Organic Synthesis, Inorganis, Catalysis, Fluorosinthesis, Enzymatic Catalysis

Mobile Chemistry:

Battery, Fuel Cell, ECDL Capacitor

Biotechnology:

Protein Purification, Buffer, Protein folding

So many people are optimistic its controbution by offering some green soluyion to many industrial sectors.

My interests for this huge thema are to collect some industrial problematic and intuitive solution in that way Ionic Liquid can probably solve problems or offer new alternative to be used. So we can perhaps open a good condusive and precise discussion or sharing.

sincerely yours,

rose line

Hi rose,

Could you give me a specific example of an "Ionic liquid"?

Mike

a prototipe of IL is of course table salt (NaCl), meltin gpoint ab. 800oC.

[EtNH3]-[NO3] has been known for many years. (mp 12 oC). ILs mean generally salts which are liquid at Room Temperature (RoomTemperatureIonicLiquid-RTIL)

Some of the new gen are known from cation type of Imidazolium, Pyridinium and may kind of anions like Triflat, Tetrafluoroborate, Hexafluorophosphate and much more. u c see by googling.

I just Googled Ionic liquid. Went ti Wiki. Have you been there?

You should go. Everything you want is there.

Thanks for ur info. Precisely I'm looking for people who has experiences workin' on ILs, in their bronxs of industry. So they can share what really works, what doesn't work. In that way I can probably share my input to them.

Hi, rose line!

Welcome to CR4! You're already making a great contribution, and I hope to see more of your particpation over time.

I noticed that in your original posting, you included: "Membrane Technology, Extraction, Gas Separation, Rectification" as applications for IL employment.

Does the application of ionic liquid technology hold out possible benefits for reducing/eliminating a CO2 remainder from exhaust gases? Is any ongoing research you are aware of addressing this concept?

Mark

Dear MarkTheHandyman,

First of all, apology for my belating reply. I was very busy last week with my job. Now I can come back to my
"hobbies".

Yes, There are many of researches working on this things. They found that in couple IL the CO2 gas has double so
high solubility as in water in ambient temperature. They made some research for
critical and supercritical condition, too. Some scientist investigate so far for potential replacement of IL as
"Green absorbent" compare to conventinal amine-based CO2 scrubber (low volatile, near to zero vapour pressure).

So I attache for you some paper about this things. You can actually find these kind of reports by googling:

Green Chem., 2009, 11, 185 - 192, DOI: 10.1039/b814246g


A potential ionic liquid for CO2-separating gas membranes: selection and gas solubility studies

Development of new gas separation methods using ionic liquids
- Technology for global warming with advantage of specific absorption phenomena of acidic gases -

Mitsuhiro Kanakubo
Research Center for Compact Chemical Process

under: Supported Ionic Liquid Membrane (SILM), Nanoporouse Membrane, Gas separation Ionic Liquid Membrane,
selectivity separation with IL membrane.


I hope this information makes a little contribute to what you"re looking for.
If any kind of discussion you will share to me, about what you're workin' on, I would love to
share with you. Don't hesitate to contact.

Ps: For case we see the needs of further consulting service, I'll refer you to our institution.

Can you give me your actual email adresse?

kindly regards,

Rose Line

Hi, rose line!

In the article, the IL process depended upon the solubility of the gas in the IL. What happens to the IL filter when saturated? Can it be recycled?

Are there any similar technologies that work using transfomation of CO2 rather than solubility to eliminate it from exhaust emissions?

Dear Mark,

Solubility behavior of CO2 makes the point interesting because they have high selectivity In compare to other gases, so they can apply this new comer of material in diff industrial process currently on going for separation process such steam reforming of fossil fuel, preparative function like gravimetric or to contribute alternative by transport process.

The energy involve by Separating Ionic Liquid Membrane (SILM) conclude the niveau of physical sorption I think, not the chemical sorption, the process don't cause any breaking of chemical bond/transformation. But I understand what you mean to get solution of exhaust emissions. I'll keep it inform for me and contact you again for this disscusion.

I have to actualize my knowing for the thema exhaust emission. You can tell my how the development any researcher in this area fro the "greener", environmentaler.

rgds,

roeslim/ rose line
