    After reading your posted links, I have to wonder why you want the information your asking for? I don't see any practical application for the average people on the street.

    KJK, thanks for your post... we'll be starting on this tomorrow, so I'll get the scoop then. But do you know of any low temp ionic liquids?

    What do you mean by inexpensive?
    What do you mean by fairly easy to make?
    What do you mean by low temp?

    Could you be a little more specific.:shrug:

    Saline is cheap because salt and water don't cost much.

    However using gold electrodes is expensive.

    So is anything that uses substantial amounts of copper.

    This is true, but what does this have to do with your original questions?

    This is also correct, but again what does this have to do with your original questions?

    Huh? New houses use a substantial amount of copper in the form of wiring and water pipes.

    Are you serious? Is this another add on to try to boost your post count for whatever reason?


    I asked my question in my op....

    OK let me be more specific.

    You asked:
    Is anyone aware of low temp ionic liquids that are inexpensive and at least fairly easy to make in the lab?

    I asked you:
    You replied
    Ionic liquids are essentially molten salt (this is what your link talked about). In other words if you raise NaCl to a high enough temperature it will melt an become a liquid - about 800C.

    So I do not understand what salt water has to do with your question.

    Are you saying to use gold electrodes to melt the salt? These are expensive and I certainly would use a different electrode material. The electrodes would be a small part of the cost of the entire setup

    Are you still discussing the electrode material or some sort of copper salt? If this is about the electrodes they are certainly cheaper than gold. Electrodes can be purchased from a furnace supply outfit that would be reasonably priced.

    Sorry, I still do not have a feel for what you mean by low temp, inexpensive and fairly easy to make?

    I need answers like this to help:

    1. I want to make an ionic liquid that melts at 300C

    2. I do not want to spend more than $5000

    3. I have never worked in a lab, so the preperation of the salt should be no more difficult than making 4 alarm chili.

    I was hoping something that would stay liquid at room temp (>20C)

    I don't want to spend more than $1-5 per liquid liter in raw materials

    I have burners, high temp flasks, etc. - basic chem lab in my home - so no spinning u238 here!

    You can use them to make solar panels, which some people do as a hobby...

    I think you are out of luck. Ionic liquids with melting temps at the level are generally dangerous (poisonous and/or carcenogenic) and really expensive.

    A friend was able to make hexaflorophosphate and Sodium (Na+ and PF6-) ...are these too expensive to make?

    Sorry for my noobish question... I've never worked with these before!

    There isn't allot of material readily available on the net about this (at least to my poor eyes!)... any thoughts would be hugely appreciated

    Make an eutectic Aluminum Chloride with Potassium Chloride

    Ir go into phase diagram books and select an eutectic point material then melt it the outcome could be a low tem ionic material.

    good lock

    I don't know what are you attempting to use

    There are some floiroborate which are relatively liquid

    If you explain the use then perhaps I can help you, I have some experience wirh Borates and some eutectic mixtures.

    Thanks for your reply!

    Attached is a copy of the paper.

    Essentially, we're trying to make a PN junction using two ionic liquids. Maybe one ionic liquid that is separated will work just fine. Naturally, the liquids should be at room temperature.

    Another good link: http://en.wikipedia.org/wiki/P-n_junction

    You can lock into Boron triflouride BF3 you can experiment by adding ammonium biflouride F
    BF3 is liquid , NH4BF4 wil be formed

    I don't Have a phase diagram book at home . You will find them in a University library and Check some Halogen salts combination , and some Boron compounds , Zinc Chloride is an other possibility
