Nitroethane Quantity?

demax - 31-5-2007 at 22:50

Hi all,

I have 2L container labelled as containing 60% nitroethane.

There is no further information and the company seems no longer to exist.

Wanting to recover this nitroethane from the solution i will attempt to distill it out. All i have is a simple distillation setup no vacuum and no fractionating column.

I will attempt this in 250ml portions becuase i am a litle frightened, collecting everything that distills over at 114C

How ok is it to proceed in this manner?

Can any body suggest some tips or safety proceedures that i should take into account?

I dont want to burn my eyebrows off!

thanks,

Demax

There was no need to open another thread on this issue.
Next time please UTFSE before posting:

Are there any advanced search options for TFSE? Could we get some?

(and, or, near, exact phrase, wildcards, etc.)

There are no such options and there won't be any until/unless the XMB developers add them. For better searching put your query into Google with "site:sciencemadness.org" at the end; they thoroughly and regularly crawl the site.

This is what i did today;

I placed 200ml of my solution containing nitroethane and im unsure what else into a flat botom flask and attached a regular distillation set up to the flask.

I turned up the heat and nothing distilled over until the temp reached 100/01 deg. C.

At this temp the drip rate was 5-6 drips every 10 seconds.

I then increased the temp to 114 C and the drip rate increased to 14 drips per 10 seconds. The solution seemed to sit confortably at this temp.

Is anyone able to give me some insight into what is happening?

It seems that this nitroethane solution is devoid of low boiling solvents etc and that it may perhaps contrain some nitromethane due to the distillate coming over at 101C or could this be some type of forerun of the nitroethane? Or is this just water distilling off, I forgot to smell it.

I contacted the supplier and they said that the percentage of nirtoethane in this proiduct is not fixed but could give no further details on what else it could contain.


thank you,

max

Yeah, I need some nitroethane too. Not nitromethane, nitroEthane, understand, Sprechen die Deutsch?

No, si parlo italiano?

Hi All,

Someone at the local uni can perform some gas chromatography analysis on this supposedly nitroethane containing solution.

Would this provide exact details of what this solution contains and the % of any substances that make up the total solution?

Can GC provide summary and detail of an azeotrope?

Are there any other tests that a professional lab could undertake apart from GC to help determine what this solution exactly is or is GC the best and only way to go?

thank you,

Max

I'd say IR and 1H NMR spectroscopy are better.

Does anyone know of or have any of the chemical nitroethane. It is the one from hundreds that i cannt obtain.

I can get LiAlH4, Dextromethorphan, THF, Benzene, 2,5-dimethoxybenzaldehyde and many more but no
nitroethane, also if anyone has it or any other interesting chemicals and is willing to trade please PM me.

Thanks, Jamie
