What's so great about d-limonene?

[red_lego_spaceman]

I've been doing A/B extractions with success, but I'd like to find an alternative to naphtha in the interest of limiting my exposure to carcinogenic chemicals. I live in a cold rainy place, so I'm often working indoors with limited ventilation and trying to evap residual naphtha in 50-degree rain sucks.

I'm very interested in d-limonene, but it seems to come with its own set of limitations. Mainly (from what I understand) you can't freeze precip with it because the DMT stays in solution when cold, and you can't just evap the limonene, because you end up with brown goo instead of crystals. So limonene seems to necessitate extra steps involving fumeric acid and then figuring out how to convert the resultant salt back to freebase.

If I'm going to do all that, what advantage does limonene have over olive or vegetable oil? Wouldn't the process be the same?

Also- to anyone who has done the conversion from dmt-fumerate to freebase, is it a difficult process? It seems like it would be- trying to separate a solid from a volatile solvent seems considerably easier than trying to dry a mixture of sodium carbonate water or alcohol-paste and freebase. Wouldn't the material you use to basify end up in your final product?

Seems like people are getting pretty good results with sunflower / safflower oil salted out with vinegar and evaporated.

what is your reasoning that naphtha has carcinogenicity?
do you have any references that would support this theory?

 

[red_lego_spaceman]

sunflower / safflower oil sounds excellent! I will try this.

Also, I'm going to burning man this year and might try to bring back playa dust to use as my base, just because it would be awesome if it worked.

I have no research to support the theory that naphtha is carcinogenic- I just assumed that all volatile petroleum based solvents were. Is this not true? I mean, I'm sure the occasional extraction isn't a big deal, but I thought it was common knowledge that long term prolonged exposure to such things was to be avoided. Especially, as I said, if you're regularly working in an enclosed space with limited ventilation.

 

[benzyme]

no, it's not true.
but you're certainly right in observing that sufficient ventilation is a good safety practice.

I advise you to check out Q21Q21's Tek. It will give you all the answers you need Good luck my friend.
