Petroleum Ether
    #5354065 - 03/01/06 04:16 PM (17 years, 10 months ago)

I am wanting to extract LSA form Hawaiian Baby Woodrose seeds, and i am haveing the problem with Petroleum Ether.

When I googled a search for petroleum ehter i came up with a few things. The biggest thing was engine degreaser, so i am assuming that this is where i get my petroleum ether.

The top 2 choices were
?Lectra Clean&II Non-Chlorinated Heavy Duty Degreaser, 15 Wt Oz - CRC02120
?Heavy Duty Degreaser II, 15 Wt Oz - CRC03120

Are these what i am looking for to make an extraction, or am I looking in the completely the wrong direction?

If these are what I am looking for, which one is better for extracting LSA?

go to wikipedia. if i am not mistaken petroleum ether is benzine.

and ether used to start diesels is diethyl ether with some other additive.

It's spelled Benzene, and no... I am reasonably certain that it is NOT benzene. Nobody would want to use benzene to extract something they planned to consume. Benzene is one of the most dangerous carcinogens known to man. Even trace amounts of it can readily cause cancer. Benzene is nasty, nasty shit. Do not mess with Benzene.

Also, ether is NOT petroleum ether, either. Diethyl Ether is actually an ether, whereas pet. ether is NOT an ether, it is merely called one. Petroleum ether is one of the most volatile substances that is refined from raw petroleum. It boils at very low temperatures, it evaporates very quickly, and it has a very low flash point (which means it is exceptionally easy to produce an accidental inferno or explosion with it). It's a fairly expensive petroleum product, I doubt it would be sold in any sort of pure form inside of a consumer product. That wouldn't be very economical.

The ingredients in the thing you listed just happened to hit the two search terms, but that's just because they contain two different ingredients, one has the word petroleum in it and the other has ether in it. Using as a solvent without even realizing that is a pretty silly way to endanger your health.
Ingredients of item 1: Petroleum Distillate/Glycol Ether "petroleum distillate" could refer, VERY literally, to every single distilled petroleum product known to man. For all you know that bottle contains 10 different petroleum products, most if not all of which are toxic.
Ingredients of number 2: Petroleum Distillate/Glycol Ether -- the same thing.

Both of them are not pet. ether. Even if they may have petroleum ether in them, they're still 100% useless unless you happen to have a cracking tower or a fairly expensive fractional distillation apparatus. Buy those if you need your engine degreased. Don't buy them for any other reason.

If you're looking to buy solvents, you're probably best off buying them from chemical companies, so that you get just the solvent and not any other additives. When you buy from a chemical company, it is fairly pure, and the label should show you the percentages of other things present. When you buy consumer goods that just happen to contain the solvent you want, you're at a significant risk of having large amounts of poisonous or just unwanted chemicals present.

BTW, isn't petroleum ether a substance that is watched by the DEA?

All these years I thought that "benzine" was a mis-spelling of benzene, when it's actually a totally different chemical. Well, you learn something new every day! :tongue:

The similarities of their names seems stupid, though. The pronounciations are identical. If you asked to buy "benzine" verbally, someone might sell you benzene instead, and that's not a good thing.

Also, I did defiitely misunderstand you about diethyl ether. You never suggested it was petroleum ether :blush:

*edit*

And, again... I recommend buying it from a chemical supplier. Spectrum Chemical sells reagent grade "Ligroin", which is laboratory quality petroleum ether. They have several different qualities of it, this one has a residue of 0.001%, which is utterly insignificant.
http://www.spectrumchemical.com/retail/p...ct%5Fid=2994924

They have a 500mL container available for $29.20. However, be aware that shipping costs will be significant due to a mandatory hazardous-materials fee. This fee would apply to any petroleum ether you had to have shipped.

Do not get benzene or naptha. Naptha has many additives that will remain after evaporation. Petroleum ether is made up of several varied hydrocarbons. Theres heptane, hexane, pentane,and many more, anything like that is highly volatile and nonpolar. These can be obtained from many chemical suppliers and online retailers in their pure form.

He's right you know, naptha is actually pretty common. All of my local hardware stores carry it. I'm lucky to have a well-managed ACE Hardware just around the corner though. They have naptha, xylene, acetone, toluene, red devil lye, and so on. It's my one-stop clandestine chemistry shopping center :tongue:
