Hi,
I have a customer wanting to use the CDA12 instead of pure ethanol. Have any of you had any issues when testing? Did you run into any issues with residual solvents?
Thanks,
thc Extraction oil ethanol
Do you have a content list ?
Cda12 Ian not familiar with
But if you can specifie the compounds used as denaturant I might be able to help
MEK,bitrex , heptane , methanol, isopropyl are often used
Hi,
It’s like a dirty ethanol and much more affordable then totes of pure 200 proof ethanol atm.
CDA12 - Completely Denatured Alcohol (CDA) 12A-1, which is 200 proof.
Ethanol, 200 Proof 95.24% (v/v)
n-Heptane 4.76% (v/v)
Water Content .2% (wt/wt)
Thanks for looking at my question.
O your good to go
Heptane is a good denaturant for extraction and should not give any isseu s with your extract
I would check all gaskets to make sure non is silicone and swap these to viton
If possible
As for water content the use of molecular sieves might be needed mostly dependent of extraction temperature

Hey,
If it is of any help, a large majority of my clients (Cannabis extractors) utilize CDA12-A (95%/5% Blend of 200PF Ethanol and N-Heptane). They have not run into any issues with testing or residual solvent, as long as the client’s separation and solvent recovery processes are up to par there should be no issues. Let me know if you would like to chat further, or if you would be interested in sourcing CDA from us, I have a strong feeling I can beat the price you currently pay, if you do not source direct from an Ethanol plant.
Hope this helps!

Not all 12-A is created equal. When using 12-A, keep an eye on your end- product analysis for oddball / unexpected hydrocarbons.
US alcohol and tobacco taxing division defines CDA 12-A as ethanol denatured by either heptane OR toluene.
Besides allowing either heptane or toluene as the 12-A denaturant, the definition doesn’t specify n-heptane. Many aren’t aware of the not so subtle difference between n- heptane and heptane. N-heptane = only the straight chain hydrocarbon. Heptane = n-heptane + some or all of it’s many isomers.

Wow, that’s amazing. And might explain some odd things i’ve seen.
