as long as the dmt is a acid salt it will not migrate into naptha used for defatting. You can also defat by soaking bio mass in naptha as the first step in extraction. This method is easy as there is no seperation required. just soak the bio mass in naptha filter the solution. Then discard the naptha allow the bio mass to dry. Then proceed with normal A/B extraction or STB extraction.
Not sure how well the xylene would work it might leave behind some crap in your spice. Has anyone tried defatting with xylene?
If you can get naptha I would not use xylene.

ok that's good, just thought i would check. thanks for your quick reply!
the only reason i'm asking is that this person recently acquired a large amount of xylene and was looking to put it to some sort of use. especially since it is a lot cheaper than good naphtha.

As far as I'm aware, aromatics like xylene and toluene are preferred for defatting as they will pull more crap.
Watch it ! I thought Xylene was THE WORST, MOST-dangerous-to-your-health NP solvent ! Don't use it 'just because it's there' ..!>
There is NO need to de-fat MHRB ! You really won't change the result by much, and will just waste NP solvent and time - totally un-necessary with MHRB
Someone said Xylene is carcinogenic, but I can't find the link !

Here's a bit from Wiki -
"Xylene has an effect on the brain. High levels from exposure for short periods (14 days or less) or long periods (more than 1 year) can cause headaches, lack of muscle coordination, dizziness, confusion, and changes in one's sense of balance. Exposure of people to high levels of xylene for short periods can also cause irritation of the skin, eyes, nose, and throat; difficulty in breathing; problems with the lungs; delayed reaction time; memory difficulties; stomach discomfort; and possibly changes in the liver and kidneys. It can cause unconsciousness and even death at very high levels (see inhalants).
Studies of unborn animals indicate that high concentrations of xylene may cause increased numbers of deaths, and delayed growth and development.[citation needed] In many instances, these same concentrations also cause damage to the mothers. It is not yet known whether xylene harms the unborn fetus if the mother is exposed to low levels of xylene during pregnancy
Besides occupational exposure, the principal pathway of human contact is via soil contamination from leaking underground storage tanks containing petroleum products. Humans who come into contact with the soil or groundwater may become affected. Use of contaminated groundwater as a water supply could lead to adverse health effects.
Stay away from Xylene man ! .. And skip defatting MHRB .... Toluene on th eother hand intriges me, although with long exposures, it's not much better than xylene !

Yes it seems to be some nasty stuff you can smell it a mile away. I have used it cactus extractions but I am not smoking the result. I know some folks say they use it with good results. I once experemented with Goof Off. I could still smell the stuff in my basement a month later.

This is from El Ka Bongs link. There is no way in hell I would use this nasty stuff. Anyone who has been using it should consider the very real danger of this solvent. Remember it will be a few years before you will know if it has given you cancer or not.
Toluene: Toluene is readily absorbed via inhalation, ingestion, and somewhat through skin contact. In the liquid form, it causes mild skin irritation with a single exposure (PDIS: 4.8/8.0) and dermatitis following repeated exposures. Toluene also produces mild eye irritation (Draise score at 1.0 hour 13.7/110.0) which includes reversible corneal opacity and iritis. It is not a dermal sensitizer. Inhalation in humans has caused mild respiratory irritation (200 ppm), mild eye irritation (400 ppm), and lassitude and slight nausea (600 ppm). Drowsiness occurs at 800 ppm. Very high concentrations may result in paresthesia, dizziness, disturbances of vision, nausea, narcosis, and collapse. It does not induce the hematopoietic effects seen with benzene exposure. Rat oral LD50: 5000 mg/kg; rat inhalation LC50: 4000 ppm (4 hours).
Acute toxicity of benzene results primarily from depression of the central nervous system (CNS). Inhalation of concentrations over 50 ppm can produce headache, lassitude, weariness, dizziness, drowsiness, or excitation. Exposure to very high levels can result in unconsciousness and death.
Long-term overexposure to benzene has been associated with certain types of leukemia in humans. In addition, the International Agency for Research on Cancer (IARC) and OSHA consider benzene to be a human carcinogen. Chronic exposures to benzene at levels of 100 ppm and below have been reported to cause adverse blood effects including anemia. Benzene exposure can occur by inhalation and absorption through the skin.
Inhalation and forced feeding studies of benzene in laboratory animals have produced a carcinogenic response in a variety of organs, including possibly leukemia, other adverse effects on the blood, chromosomal changes and some effects on the immune system. Exposure to benzene at levels up to 300 ppm did not produce birth defects in animal studies; however, exposure to the higher dosage levels (greater than 100 ppm) resulted in a reduction of body weight of the rat pups (fetotoxicity). Changes in the testes have been observed in mice exposed to benzene at 300 ppm, but reproductive performance was not altered in rats exposed to benzene at the same level.
This product contains xylene. Xylene is readily absorbed through the skin. It is also absorbed when inhaled or ingested. Overexposure to xylene can cause eye and respiratory irritation, drowsiness, headache, fatigue, irritability, and gastrointestinal disturbances. Some liver damage and lung inflammation were seen in chronic studies in guinea pigs but not in rats. In rat reproduction studies, xylenes did not produce birth defects but were toxic to the embryo when toxicity to the mother was produced. In a mouse study, xylenes caused birth defects at doses that threatened the life of the mother. The doses which produced these effects were greatly in excess of the TLV. Rat oral LD50: 4300 mg/kg; rat inhalation LC50: 5000 ppm/4 hours.
Aspiration of this product into the lungs can cause chemical pneumonia and can be fatal. Aspiration into the lungs can occur while vomiting after ingestion of this product. Do not siphon by mouth.

Scary huh ..!? the stuff in many NP-solvents just seeps into you, through the skin, while it's lashing at your lungs ! Ever used alkyd paints ? They too are pretty toxic ...
So evaporate it ALL - naphtha, toluene, diethyl ether, DCM, ... the double distilled-'low odor'- painter's thinner ! And do it nowhere near you or anyone else ! But those LD-50's are still high compared to other chemicals, like pesticides - poor guinea pigs ! ... rats too, having to chug the stuff !
