Isopropyl Oil Help

[G33k Speak]

99 iso is bad, it has a little benzene inside. 95 is better, 5 is just a little water.

That doesn't make any sense.

 

[Monad]

I use 99% ALL the time.....whats this benzene??????

don't put ur stove on high, if you want it to evaporate faster:
-get one of those splatter screens for deepfrying/cooking with oil (to stop hair n debree from blowing into ur hash)
- and a nice big floor fan set on high

Just check the ingredient list on the bottle, mine is isopropanol 99%, it says

Medical Ingredient:99% isopropyl Alcohol
Non-Medical Ingredient:water

So im fairly sure the iso im using has no benzene, which is a known carcinogen.

it's just a question of physics: you can't make iso purer than 95% without benzene inside. It's like trying to light a joint without a fire.

They don't list it because it's in very small ammount, but still it is there...

No. Isopropanol alcohol is made by combining H2O and propene by either direct, or indirect hydration, no benzene at all. Benzene doesn't do a thing to remove more water from that chemical compound, it's a solvent itself. You have to use a desiccant and a vacuum to remove more water from Iso to make it more pure. The only reason you can't get 100% is because the alcohol absorbs that .1% of H20 from the atmosphere. If you could keep it under a vacuum it would stay at 100%.

Now if you were to have said Benzophenone, which is a desiccant, but not one you would use with isopropanol alcohol. That would be a different story, but still incorrect.

quoting wikipedia :

[...]

Isopropyl alcohol and water form an azeotrope and simple distillation gives a material which is 87.9% by weight isopropyl alcohol and 12.1% by weight water.[3] Pure (anhydrous) isopropyl alcohol is made by azeotropic distillation of the "wet" isopropyl alcohol using either diisopropyl ether or cyclohexane as azeotroping agents.

[...]

In chemistry, azeotropic distillation[1] is any of a range of techniques used to break an azeotrope in distillation. In chemical engineering, azeotropic distillation usually refers to the specific technique of adding another component to generate a new lower-boiling azeotrope that is heterogeneous, such as the example below with the addition of benzene to water and ethanol.

As i studied it in high school, azeotropic distillation has to be made with benzene.

Anyhow i'll be happy to be proven wrong, since the chemistry we studied was yet old.... in the past century!

 

[G33k Speak]

Do you have a label or MSDS to show benzene content???

 

[Monad]

the ISO I buy doesnt say sh*t on the bottle....wonder what they'd say if I gave em a call...

ya but your quote lists two other chemicals that are used instead, not benzene.

 

[gramsci.antonio]

usually they use ethanol or benzene (the ones that are listed). But since in most of the countries of the first world ethanol is heavily taxed, and since most of the azeo. distillation machine are built in the those countries thinking that they would have been used with benzene, the latter has became a standard de facto.

 

[Hashmasta-Kut]

no these are the ones listed in your top quote "diisopropyl ether or cyclohexane "

you just won one kudos my bad.

 

[dude06version]

yea that stuff in the coffee filter wont get you high... it smells good and taste horrible but itll just give you a headache...you arent wasting anything..all the good stuff was in the iso solution...trust me

 

[thinman]

surely people can't be so cheap, frugal, whatever....i have done it with iso/alcohol in different strengths....then i tried with everclear grain alcohol and it made all the difference in the world. i like to leave the oil made with everclear a little runny. it has a wonderful sweet flavor that everyone enjoys.
