Whitch naphta could be used for extraction..only petroleum ether or pait petroleum essence too? i asked for ether today but guy said me they've only 'petroleum essence' would it works? :roll:
thanks
 
petroleum ether should be equivalent to naphtha.. what makes you be "pretty sure" it wouldnt work well?

always check msds of the particular solvent you can find to see if it contains anything other than what is wanted (aliphatic hydrocarbons in this case)
 
Is freeze precipitation possible with pet ether? I have no idea what the XlogP is and would assume, probably wrongly, that it would be around ethyl ethers which is 0.9. That would make it to soluble, no?
 
No, as I said, pet ether = naphtha. It would have a much higher XlogP, as naphtha, so it would work for freeze precipitation.

Did you guys even bother doing a simple google search? It would also tell you that pet ether is like naphtha and that its not an ether.

In chemistry, you cannot suppose something is equivalent to some other chemical (for example pet ether = some other ether) just because of the name, you're bound to make serious mistakes like this. Please research :)

The only issue, which is regardless of being pet ether or naphtha or whatever, is that any new solvent being used might be pure or it might have additives or what not. Different solvents are sold for different purpouses so even if theoretically its something you want, it might have unwanted additives or mixes. For example some solvents sold as 'fuels' can have anti-rust inhibitors which might be toxic, or certain naphtha might have mixed in aromatics (like xylene) which will make it impossible to freeze precipitate and it will pull more stuff than just dmt, etc. So its not just because the main name on the label is familiar that you can automatically use it.

Thats why with every solvent you are using for the first time, you have to thoroughly check it in many ways (Evap test, read label, try to find msds of product, etc)

and thats exactly why we have this thread here and the links in the second post there: The official "Is this chem ok to use? / Where can I find ...?" thread - FAQ - All your basic questions and answers - Welcome to the DMT-Nexus

Please check thoroughly any solvent or chemical you are going to use.
 
Sorry bout that all. Hope my inexperience with other solvents didn't confuse or mislead. I've never used pet ether but was also curious as to how it would work in comparison to more common solvents. I probably could've googled it and wouldn't have even needed to ask :oops:
