95% ethanol for carbon dosing
Is it OK to use 95% ethanol for carbon dosing? I used to dose vodka and it's getting too expensive with my massive system, experimented with diluted glacial acetic acid and the ph swing scared the hell out of me.

How expensive is vodka in Indonesia? In the U.S., 2 liters (half gallon) is $8-$12.

If it is 95% ethanol and 5% water, that is fine.

Thanks a lot!! Assuming we are dosing 0.6ml/100lt with 40% vodka we can just recalculate it for using 95% ethanol? As I remember majority of vodka doser ends up with 0.4 - 0.6 ml / 100lt? Please correct me if I am wrong?

To compute the dose for 95% ethanol, take the numbers for 80 proof (40%) vodka, and just multiply by 0.40/0.95, or about 40%.

If it's not meant for drinking, it's denatured (to avoid taxes encountered with drinking). There are two common ways it's denatured: with methanol/isopropanol or with benzene. You don't want to add benzene to your tank (methanol and isopropanol are fine).

Still, I won't be using it again - I found out one of our solvents here at work is 2-3% methanol, 2-3% IPA, 94-96% ethanol per my own GPC analysis and we get it in 500 gallon totes :P I was told I could take a quart or two any time I wanted to. |

For dosing, if you want to be very close, dose methanol at 70% the volume of ethanol you currently dose -- assuming both are at the same volume % (100%, 40%, etc). (They have essentially the same density, but their MWs are different). |

I'd consider it experimental to use methanol in a setting where everything is exposed to it, and acetate (vinegar) is a much more common part of the natural cycle of organic compounds in marine systems.
But it may work fine.

That'll be fine as long as it's ethanol and water.

It’s most likely denatured with a chemical compound such as benzene. If it states it is denatured I would just avoid it.
