Isobutane and Stability....

[Gtir]

Stopped the system at 10, 20 and even 30 psi(Dont Do That), to try to pour soup....

By the time your at 0 psi, its super fluff and unpourable....

2"X36" molecular sieve.....


Took a pic as I was flipping slabs last night...

So you're having nice stability w the new mix?

Is it possible that's just a result of new solvent w less water in it?

My initial run with isobutane was the first time I used it after distilling, and could not get stable...

Now with the added propane its perfect stability. Between hard shatter and pull n snap...

Easy to carry in your hand and easy to snap little pieces off, but still pliable....

12.95 ISO / 48.8%

7.95 prop / 30%

5.6 N / 21.1%

I will try this tommorow, I've been experimenting w solvent mixes for a while now. You bought the 70/30 ISO/propane from ecogreen right? They don't sell a ISO/n

How did you mix the solvents? Did you move them w the liquid side or vapor side? Because if you moved by pulling vapor then that changes the mix.

What is your pressure/temp of your solvent tank?

Moved by pulling vapor....

I dont have a pressure or temp gauge on my tank, upgrading to a SS one here soon...

I notice running this mix, it seemed about 20psi higher then straight nbutane. Where as the oil at 20psi with this mix, looks like 0 psi with nbutane...

You mentioned 70/30 ISO, is that this https://ecogreenindustries.net/product/isobutane-custom-blend-7030-99-97-purity/

If so an you didn't pull all of it from the vapor, you changed the ratio

I sure did...

Hello, I only use isobutane (white clipper not the yellow one) as it is the only ultra refine gas available here. I have made great shatter with it, very stable with good color made from buds only

Usually canned butane is a mixture of propane, isobutane, and butane. Without a little propane there's not enough pressure to keep a flame going at cold ambient temperatures.

You can test what you have yourself with a thermometer, squirt some into a container, and observe the boil off temps,

Propane boiling point −42.25 to −42.04 °C; −44.05 to −43.67 °F; 230.90 to 231.11 K

and then,

Isobutane boiling point −11.7 °C; 10.9 °F; 261.4 K

and finally,

Butane boiling point −1 to 1 °C; 30 to 34 °F; 272 to 274 K

What solvent are you using now? I'm around an hour from the bay can you recommend me a good supplier? Thanks.
