environmental impact of BHO extraction

[illchemist]

Trust me, I love BHO and all that it offers: the supercritical fluid extraction, the look, the smell, taste, blastoff... but evaporating hydrocarbons into the atmosphere is one of the main sources of ground level ozone pollution. Why add to the problem?

Volatile hydrocarbons (solvents, gasoline, etc.) enter the atmosphere and react with the intense UV light up there. This creates a free radical that reacts with oxygen (O2) to make ozone (O3). This ozone is one of the main lung health concerns in major cities.

A solution to the problem would be to use another low-boiling, non-polar, solvent like pentane or hexane and recover the solvent by means of distillation. The solvent can then be recycled. However,you lose some of the ultra-selective benefits of the supercritical fluid. If you want to retain the selective benefits of supercritical fluid extractions, please use super-critical liquid CO2 as this is readily abundant and non-polar (maybe we could sequester the worlds CO2 output for CDHO production? ). It should produce similar results.

Or maybe just walk to the store instead of driving? A lifetime of that would probably offset any amount of BHO you'd make.

If I was making BHO for my whole town, I'd worry more about the damage to the environment, but I'm sure my car is a bigger problem.

Why not just tell everyone to stop driving cars..........why add to the problem right?

I dont think anyone here, and really anyone in general uses supercritical hydrocarbon extraction systems. supercritical conditions for hydrocarbons are deadly for most small organic molecules. (the temperatures are very very very high, much higher than for CO2, like 500 C instead of 30-80 C for CO2)

there is a well known area called "high pressure hydrocarbon extraction"

I am fairly certain that the main culprit in low atmosphere radical/ozone generation are nitrogen oxides (NOx), CO2, and PCAHs (polycyclic aromatic hydrocarbons). the added butane due to BHO essentially leaves the total hydrocarbon concentration in the air constant. BHO has little effect. In fact, I would be willing to bet that the biggest effect is from livestock and swamps (frozen or unfrozen).

also keep in mind that 99.99% of research institutions just blow all of the fumes RIGHT out of the roofs of their buildings.

one more thing:

never heard of a PPA analogue of mescaline. Shulgin writes in PIHKAl that the PPA analogues have "uninteresting" affects in rabbits and are overall inactive as stimulants.

is there a street name for this PPA analogue?

here is a quote from PIHKAl:

"What happens if you extend the chain to a third carbon? The parent system is called the phenyl--propylamine, and the parent chain structure, either as the primary amine or as its alpha-methyl counterpart, represents compounds that are inactive as stimulants."


also supercritical CO2 fucks up THC (high pressures and ridiculous excess of electrophilic carbons dont do well with nucleophilic moities)

I'm not cutting down my BHO making until they make some kinda of civilized standards for the livestock/ factory industry. they are the problem

If my factory was polluting the plant on a grandiose scale i might feel more apt to care. I don't feel it is right for you to impose artificial stresses on this community. If you want to make a difference do it on a large scale. It's good to plant a seed, but asking other's to abstain. So that large corporate America and World industry can fuck up on a global level. It's bigger than you or I. Take that info, make it applicable to industry. My bho's not hurting anyone, more than it's helping my community.

no so conducive to some peoples lifestyles. i tries the woods. not too many hot models wandering around needing to be photographed. killed the income.

12 cans of colibri

 

[Hashmasta-Kut]

how much weed for ten cans? i use about 15-20gs per can..

 

[Chiefsmokingbud]

^^^no doubt, me too

 

[coop]

i use even less hmmm looks at yeilds, maybe time to use more

 

[Verite]

I balance it out. Every batch of bho I make I then get real high and go out and flatten the tire on a Hum-vee.

 

[Chiefsmokingbud]

LOL, i was wait'n for verite to show up with the comedy

 

[Canabudz]

i used about 1 can per 15g

 

[Canabudz]

poof
!

 

[Hashmasta-Kut]

who is that masked zappa fan anyhow, i cant recall..

 

[Canabudz]

i had only seen pics of them maybe once or twice on this site, and i was pumped when i saw one. are those pieces available to the public in bc?

 

[Hashmasta-Kut]

i sent it to him. or he picked it up in person. he must frequent the internet to have acquired it, unless it was in person. its my design, and my sister does the glass work.

 

[Hashmasta-Kut]

ok i know who's vape that is. i got confirmation from the actual owner, who isnt possesing it right now.

trippy.
