The source of oil that we have titrates @ between 8.5 - 9.5 g/liter. Do you guys have a recommendation on the best way to process oil this acidic? thanks.

Use 22% methanol by volume ratio instead of 20% and process it like normal, your yield will be about 85%. The only other thing you can try is blend it with a lower titrating oil or add some glycol from a previous batch to bring the titration numbers down.

i wouldn't be worried if you are using NaOH. That is where a lot of oil I use titrates.
I use 25% methanol and process for ~ 90 minutes. always passes the 3/27 test.

We are using KOH. We are also looking @ mixing with less acidic oils, but right now this is the only source that we have. Never thought about adding glycerol from a previous batch, might be something to look at. We were thinking of using 22% methanol also.

It is reassuring that you are using oil that titrates that high also. The other place that we want to get oil from titrates @ 1.7 mg / ml, but he is locked into a contract until April.
thanks,
Trent

Trent, with KOH the base is 8. are you saying you need to add 9 grams to the base?

yes, unless we decide to use the acid-base method. This will be the first large batch for us, so I'm not too excited about trying something new, especially where H2SO4 is involved.

17 grams/liter is a lot. have you run another titration to be sure?

are you warming the methanol & oil when you are mixing them together?

I re-ran samples that I had done when I 1st made the solution and familiarizing myself with the process and got the same results, so I think the KOH solution is still good.
Sorry empiretc, the methanol reference made me think you were talking about the actual reaction and not the titration. I have been using Isoprophyl alcohol for titration.
